Agri-cultural Heritage: An Interdisciplinary Field with Development Prospects

Traditional agricultural heritage research has a very long history. Programme on “The conservation and adaptive management of Globally Important Agricultural Heritage Systems (GIAHS)” initiative launched by FAO in 2002, aimed at not only preserving agricultural heritage system, but also applying the principle of dynamic conservation to promote rural development to benefit local community, to assure food security and maintaining the ecosystem. Since then, many more scientists have been enrolled in the new field focusing on the function and value, application and management, conservation and development and other aspects of these traditional agricultural systems which facilitate an emerging cross-discipline. In this paper, based on the concepts and characteristics of GIAHS and China Nationally Important Agricultural Heritage Systems (China-NIAHS), the author specifies that Agri-cultural Heritage is a compound heritage that integrates the characteristics of natural, cultural and intangible cultural heritage, and a typical social-economic-natural complex ecosystem composed of economic, biological, technological, cultural and landscape components. For their conservation and development, the joint efforts of scientists from economics, ecology, geography, history, management sciences, culturology, ethnology, sociology and other subjects are needed. Based on progresses studies and perspectives of the field, the author felt that although a good start of the research on Agri-cultural Heritage has been made, there is still much room for development which show a steady growth trend and suggested 32 priority areas in research; a new subject of Agroheritology could emerge in the near future.     

Progresses and Perspectives of the Resource Evaluation Related to Agri-cultural Heritage Tourism

The scientific evaluation of tourism resources is not only an important prerequisite for the development of agri-cultural heritage tourism (AHT), but it can also promote the conservation and management of Important Agricultural Heritage Systems (IAHS). With the goal of providing scientific support for the sustainable management of tourism resources, this review systematically analyzes the overall situation, research regions, developmental timeline trends, key fields and hot topics of resource evaluation research related to AHT over 2005-2020. With a comprehensive perspective that incorporates both traditional literature review and quantitative literature review, the study revealed four important aspects of AHT research. (1) Relevant articles could be divided into two phases, a development-oriented period (2005-2012) and a conservation-oriented period (2013-2020). (2) GIAHS accounts for the absolute majority (about 66.7%) of relevant studies. In particular, Longji Terraces System, Hani terraces system and Dong’s Rice-Fish-Duck System were the research hotspots IAHS, and Yunnan, Zhejiang and Guangxi were the research hotspot provinces. (3) Terraced landscapes and tea culture were the most popular themes in tourism resource evaluation, while sports tourism, tea culture tourism and study tours are becoming the new trends in IAHS sites. (4) Research methods have undergone a shift from qualitative to quantitative approaches, and a combination of these two in an interdisciplinary manner is becoming a new research trend. By reviewing and prospecting the relevant literature, this study not only makes a unique contribution to the tourism resource evaluation of IAHS, but also helps to enrich the relevant evaluation theories and further promote the sustainable development of heritage tourism from theoretical and methodological perspectives.     

Conservation of the Important Agricultural Heritage Systems in the Economically Developed Area：Experiences,Problems and Solutions—A Case Study of Zhejiang Province

Zhejiang Province, located in the Yangtze River Delta region, is representative of China's economically developed areas. It enjoys superior natural conditions and a long history of agriculture, and is a comprehensive agricultural area with integrated development of agriculture, forestry, animal husbandry and fishery. It has nurtured the farming culture represented by Hemudu culture and Liangzhu culture, which have given rise to numerous precious Agricultural Heritage Systems. At present, Zhejiang Province has three of the world’s Globally Important Agricultural Heritage Systems (GIAHS) and 12 China Nationally Important Agricultural Heritage Systems (China-NIAHS), so it not only has the largest number of heritages in China, but it has also attained remarkable achievements in heritage conservation. Taking Zhejiang Province as an example in combination with the rural revitalization strategy, this paper summarizes the achievements in the protection of Important Agricultural Heritage Systems (IAHS) in Zhejiang Province during the past 15 years from the aspects of increasing farmers’ income, cultural Inheritance and industrial upgrading, as well as the conservation experiences in government promotion, community initiative, enterprise participation, technology driving and social linkage. Further, in view of the problems that exist in the current heritage protection,such as imperfect management of heritage sites, low participation of community residents, lack of special protection funds, and imperfect provincial management system,the following countermeasures and suggestions are put forward: (1) Improve the management mechanism for the conservation and development of Agricultural Heritage Systems; (2) Develop regional public branding of agricultural products in Agricultural Heritage System sites; (3) Increase the Agricultural Heritage System science education as well as cultural and creative product development; (4) Carry out the evaluation and recognition of IAHS at the provincial level; and (5) Provide substantial support and input to the conservation and utilization of IAHS. This study can provide some guidance for the conservation of IAHS in Zhejiang Province and it provides important reference for IAHS in the economically developed areas in China.     

农业文化遗产地文化关键种的概念、内涵和意义

包括联合国粮农组织(FAO)认定的全球重要农业文化遗产(GIAHS)和一些国家农业部认定的国家重要农业文化遗产(NIAHS)在内的农业文化遗产是一种新的遗产类型,通常具有丰富的生物多样性、多元的传统知识、独特的资源利用技术、杰出的文化景观,是一个典型的社会-生态系统。文化关键种作为塑造了一个地区的社会文化特征的重要物种,可以作为研究社会-生态系统保护与恢复力提升的一种独特视角和方法。本文通过系统梳理文化关键种概念的起源与内涵,分析了它们与生物文化多样性和社会-生态系统保护之间的关系,并结合农业文化遗产的基本特征和保护需求,尝试对农业文化遗产地文化关键种给出了定义,即"在农业文化遗产系统内,由生物资源和文化实践紧密结合,对当地社会文化的稳定性产生重要影响且能够促进农业文化遗产保护目标实现的生物文化复合体"。在此基础上,进一步分析了识别农业文化遗产文化关键种对农业文化遗产保护的主要意义:一是通过文化关键种的识别与保护有助于遗产地关键要素的识别和保护;二是利用文化关键种社区认同度高的优势可以调动社区参与遗产保护的积极性;三是以文化关键种的识别与保护为切入点,有助于更好地实现全球或国家重要农业文化遗产保护目标,即保障食物与生计安全、保护生物多样性、促进传统知识与技术体系传承以及维持景观特征等。     

The Role of Local Knowledge in the Risk Management of Extreme Climates in Local Communities: A Case Study in a Nomadic NIAHS Site

In the context of climate change, research on extreme climates and disaster risk management has become a crucial component of climate change adaptation. Local communities, which have been facing extreme climates for a long time in their production and daily life, have developed some locally applicable traditional knowledge that has played an important role in their adaptation to extreme climate and disaster risk management. Therefore, this research aims to link Local knowledge (LK) to community extreme climate disaster risk management in order to construct a conceptual model. It then takes the extreme climate adaptation strategy of traditional nomads in a temperate grassland of China as an example to analyze the role of LK in extreme climate adaptation using the proposed theoretical framework. The main research objectives of this study are: (1) To construct a conceptual model to illustrate the relations among extreme climate events, risk management, LK, and farmers' adaptation strategies; (2) To apply the theoretical framework to a field case to reveal context-specific extreme climate adaptation mechanisms with LK as a critical component; (3) To test the framework and provide suggestions for the extreme climates adaptation, and the conservation of LK related to climate change adaptation. The results show that from the perspective of disaster risk management, local communities could manage extreme climates as a disaster risk through adaptation strategies formed from LK, because as a knowledge system, LK contains relevant knowledge covering the whole process of disaster risk management.     

中国农业文化遗产研究的进展与展望

中国农业文明历史悠久,勤劳智慧的劳动人民在长期的生产实践过程中一直在探索适应不同自然条件的农业生产方式,创造了灿烂的农业文化遗产。当今农业发展所面临的面临生态系统退化、面源污染严重、遗传资源丧失、食品安全问题严重等问题,促使人们转而学习传统农业的智慧与经验。本文从基于文献的传统农业文化遗产研究和基于实践的动态保护与适应性管理研究两个方面,较为系统地回顾了中国农业文化遗产研究的主要进展。指出,积淀深厚、成果丰富的农业历史和农业考古研究,为农业文化遗产保护实践和发展生态农业奠定了坚实的基础。2002年联合国粮农组织（FAO）发起的全球重要农业文化遗产（GIAHS）项目,则极大地提高了人们对农业文化遗产价值的认识,使农业文化遗产保护研究与实践进入了一个新阶段,在农业文化遗产的概念与内涵、农业生物多样性、多重价值、替代产业发展以及法律与政策保障等方面都有新的探索。未来研究中应进一步丰富研究内容,改进研究方法,深入开展农业文化遗产的保护和利用的探索等。     

中国重要农业文化遗产可持续发展面临的挑战与应对(英文)

2012年农业部启动中国重要农业文化遗产发掘工作以来,通过两批申报与评选,有39个传统农业系统入选中国重要农业文化遗产,其中涉及林业19项、种植业14项、农业复合系统4项、其他2项。从遗产系统的起源来看,历史在1000年以上的农业系统有24个。从民族特征来看,20个遗产系统位于少数民族聚居区。当前,农业文化遗产地普遍面临着生态系统的退化与破坏,传统农业技术和农业景观的遗失与废弃,农业规模化与产业化发展滞后,农户的利益分享与激励不足等问题。相对其他遗产类型,农业文化遗产的保护与发展更为复杂和困难。为实现农业文化遗产的可持续发展,要充分发挥政府的主导作用和财政扶持功能,探索农业文化遗产保护与发展的市场化途径与适应性管理,建立多方参与和惠益分享机制,加强农业文化遗产的基础研究工作。     

全球重要农业文化遗产(GIAHS)保护与适应性管理(英文)

世界各地世代居住的农牧民,以多样化的自然资源为基础,通过因地制宜的生产实践活动,创造、形成并保持着许多独具特色的农业系统和景观。这些在本土知识和传统经验基础上所建立起来的农业文化遗产巧夺天工,充分反映了人类及其文化多样性和与自然环境之间深刻关系的演进历程。这些系统不仅维持并适应了具有全球重要意义的农业生物多样性,形成了丰富的本土知识体系,而且更为重要的是,还为人类持续提供了多样化的产品和服务,保障了食物安全和生计安全,提高了人们的生活质量。但是,许多这样的农业生产系统正面临着包括全球化在内的多种影响因素的威胁。2002年,联合国粮农组织发起了一个国际合作计划"全球重要农业文化遗产(GIAHS)保护与适应性管理"。这一全球性倡议旨在建立这些农业文化遗产及其有关的生物多样性、食物与生计安全、景观与文化的保护体系,并在世界范围内得到认可,实现动态保护和可持续管理。     

Ecological Benefit Evaluation of Agricultural Heritage System Conservation—A Case Study of the Qingtian Rice-Fish Culture System

In order to better understand the developmental conditions and trends of the biodiversity at agricultural heritage sites, the structure and function of the ecosystem and ecological environment in Qingtian Rice-Fish Culture System is examined in the decade since the implementation of the GIAHS project. Through the collection of historical data and sample-plot survey, this study collates the data from 2005 to 2013 related to the heritage site to evaluate the ecological benefit of the Agricultural Heritage System conservation. The results show that: (1) Since the implementation of heritage conservation, the variety of traditional rice grown at the heritage sites basically remains stable, the varieties of other crops basically remain unchanged and the varieties of fruit trees and medicinal plants have developed at faster rates. As the ecological environment at the heritage sites gradually improved, the species and richness of the biodiversity in the ecosystem have increased, especially the increasing growth of egrets and boars. (2) From 2005 to 2013 in the Fangshan Town of Qingtian County, the ecosystem areas identified as river, forest, urban and bare land have increased. The increased area of the urban ecosystem is the largest one of them, which is up to 20.30 ha; while the area of the forest ecosystem has increased to 7.29 ha. The areas of wetland, reservoir, farmland and grassland have been reduced, and the area of grassland ecosystem has been reduced the most with a reduction of 28.87 ha. From the changes in the values of the ecosystem services of different ecosystem types, the values of forest ecosystem services have achieved the most growth, reaching up to 92000 yuan yr^-1 and the growth of the river and bare land ecosystem service values are not obvious. (3) Over nearly a decade, the soil nutrients and the water quality of rice fields at the heritage site have not obviously changed and the plant diseases and insect pests in the rice fields have not been aggravated. The monitoring indexes are far better than the standard values. With the great support of the local government, the production and living conditions and the living environments of farmers in the villages of the heritage sites have been greatly improved through road reconstruction, water improvement, toilet enhancements and the greening, brightness and beautification of the villages.     

Perceptions of Local People toward Wild Edible Plant Gathering and Consumption: Insights from the Q-method in Hani Terraces

Wild edible plants (WEPs) can provide a variety of provisioning services and cultural services but they are currently under-utilized. Understanding farmers’ perceptions of the collection and consumption of wild edible plant resources is essential for promoting local socio-ecological system resilience and local wild plant resource use. This paper uses the Q-method to investigate the main perspectives of farmers toward collecting and consuming wild edible plants in the Honghe Hani Terraces region of Yunnan Province. This analysis identified four main perspective types among the farmers, including market-driven, household user-driven, cultural service seekers, and tradition followers. It revealed the main factors that limit and facilitate farmers’ WEP collection and consumption, including limitations due to loss of traditional knowledge, and changes in socioeconomic conditions that negatively affect WEP collection and consumption; while, on the other hand, the demand for WEP-related cultural services and the presence of a strong culture slowed down changes in dietary structure, which in turn have maintained WEP collection and consumption. The Q-method can help in identifying the relationship between community residents and local wild plant resource use in rapidly transitioning areas and in identifying the barriers that affect the resilience of local socio-ecological systems.     

Design and Application of the Annual Report of Globally Important Agricultural Heritage Systems (GIAHS) Monitoring

Scientific and effective heritage monitoring can not only realize the conservation of the heritage itself and the maintenance of its values, but it can also realize the sustainable development of the heritage site. In order to promote the conservation and management of Globally Important Agricultural Heritage Systems (GIAHS), this study proposed a design for the annual report of GIAHS monitoring under the overall framework of the GIAHS monitoring system, and explored the application of the annual report in the first GIAHS site in China: the Qingtian Rice-Fish Culture System. In the design scheme of this study, the GIAHS annual monitoring report is composed of 24 monitoring items, with each of them logically related. It is to be filled in by the bureaus of the heritage site and reported through the GIAHS dynamic monitoring system. The results of an analysis of the annual reports of Qingtian Rice-Fish Culture System for four years showed that Qingtian County has taken a series of conservation and development measures which have reduced the area of abandoned paddy, enhanced the unit benefit of agri-products, and increased the farmers’ income. At the same time, the heritage site is faced with various challenges and threats, such as the weakening of the tourism attraction, the aging of the heritage practitioners, and the limitation of the heritage-themed agri-products and tourism income, which need to be addressed with proper measures. The results can also provide guidance for other GIAHS based on indications that heritage sites should improve the development of cultural products, the construction of social organization and the cultivation of spontaneous publicity, and an exchange and learning mechanism should be established among them in the future. The design and application of the GIAHS annual monitoring reports can not only provide specific guidance for conducting the GIAHS monitoring, but also lay the foundation for evaluating the effectiveness of GIAHS conservation and management. This study is expected to help enrich the theory of GIAHS monitoring, further promote China’s GIAHS monitoring work, and also provide China’s experience for the benefit of international GIAHS monitoring efforts.     

Calculation of Ecological Compensation Standards for the Kuancheng Traditional Chestnut Cultivation System

Kuancheng Traditional Chestnut Cultivation System is located in the Beijing-Tianjin-Hebei Water Containment Function Area. The Traditional Chestnut Cultivation System is characterized by agroforestry compound, and some studies have shown that the compound planting of chestnut has better ecological benefits than the single chestnut planting mode. However, most of the local farmers in Kuancheng are mainly engaged in single chestnut cultivation. Through ecological compensation, farmers are being encouraged to change their chestnut planting mode, which can achieve the purpose of inheriting China’s important agricultural heritage and improving the ecological benefits. This paper introduces preference coefficients to correct for opportunity costs, and through interviews and questionnaires, we obtained the input and output of the single chestnut cultivation, chestnut-maitake, chestnut-millet, and chestnut-chicken and the income of laborers working outside the home in the Kuancheng area. Through analysis and calculation, we obtained the following results: (1) Although the net income of the three chestnut composite modes is higher, their economic input is higher than that of a single chestnut planting mode, and the return on unit investment is lower. (2) The average income of young and middle-aged workers who work outside is higher than that of the local farming industry, so the local chestnut agroforestry plantation has a higher opportunity cost. (3) The final calculation shows that the chestnut-chicken agroforestry operation mode needs no compensation, the chestnut-maitake plantation mode is compensated at least 1608.5 USD ha^-1 yr^-1, and the minimum compensation for the chestnut-millet plantation mode is 198.3 USD ha^-1 yr^-1, which can guarantee that farmers receive the full value of their creations. Ultimately, farmers are incentivized to revive the traditional agroforestry production mode to achieve both economic and ecological benefits while inheriting agricultural heritage.     

The Significance of Traditional Culture for Agricultural Biodiversity—Experiences from GIAHS

Agricultural biodiversity has a high importance in social-cultural, economic, and environmental aspects, and can help in adapting to and withstanding climate change. Conserving the GIAHS sites and the important components within them can help conserve the agricultural biodiversity and traditional agricultural culture of the whole country. This study considered Ifugao Rice Terraces, Dong’s Rice-Fish-Duck System, and Hani Rice Terraces System as three examples which show that traditional culture can be used to protect agricultural biodiversity, while as a carrier of traditional culture, agricultural biodiversity also conveys and protects the traditional culture of the nation. According to the analyses, through several years of efforts, the status of agricultural biodiversity and traditional culture in them has improved. Then, to further promote agricultural biodiversity conservation and traditional culture protection, several suggestions are made, such as establishing community seed banks; documenting and preserving traditional farming methods, techniques, and tools and developing participatory activities which encourage more farmers to participate in the protection work.     

日本虎杖覆盖对连作的影响——日本西阿瓦陡坡土地农业系统传统耕作评价

禾本科物种(例如银草、芦苇)在日本传统的地膜覆盖农业中普遍使用,西阿瓦地区是全球重要的农业遗产系统(GIAHS)所在地。传统上,这里的农民使用银草覆盖农业土壤。但当地农民从长期的经验中了解到,日本虎杖覆盖更适合该地区茄科作物的种植。目前尚不清楚日本虎杖覆盖物为何对茄科作物的种植有益。在本项研究中,我们假设日本虎杖覆盖物可能会有效避免连续种植马铃薯的危害。因为过去每年都会种植两次本地马铃薯,因此,我们调查了日本虎杖覆盖对连续种植马铃薯以及番茄种植后对马铃薯产量的影响。在2018年进行的田间试验中,我们首先在连续马铃薯栽培的土壤和未耕种的土壤中比较了日本虎杖覆盖、银草覆盖和无草覆盖(对照)对马铃薯产量的影响,结果表明日本虎杖覆盖减少了马铃薯产量的降低程度。其次,我们比较了番茄种植后的土壤和未耕种的土壤中的虎杖覆盖和无草覆盖对马铃薯产量的影响,结果再次表明了日本虎杖覆盖减少了马铃薯生长和产量下降的程度。这些发现表明用日本虎杖覆盖有助于避免连续种植马铃薯的风险。     

Tameike灌溉池塘农业文化遗产:以大分县国东半岛为例（英文）

本文以于2013年5月被认定为全球重要农业文化遗产(GIAHS)试点的国东半岛为例,探讨了日本tameike灌溉池塘成为农业文化遗产的潜力。"tameike"是这个地区主要用来储存泉水或者短小急流的一种小型池塘。国东的tameike建造与当地的水稻种植和林业发展关系密切。许多现存的灌溉池塘均建于江户时期(1603–1867),直到战后这些池塘都是通过传统农业技术进行管理。然而,随着经济发展,这些灌溉池塘的用途和生态系统功能迅速减少。目前,灌溉池塘的总数只有明治维新前的近三分之一。GIAHS项目试图重新评估这些灌溉池塘的生态系统功能和相关知识体系以振兴当地农业。本文基于文献调查和实地研究,提出合理管理灌溉池塘可以成功使这种资源循环利用的文化恢复生机,而这正是国东地区作为农业文化遗产的意义。     

Suppressive Effects of Traditional Mulching Using Japanese Knotweed (Fallopia japonica) on Solanaceae Crop Diseases

Poaceae plant species, such as silver grass, are commonly used in mulching activities Japan. In contrast, local farmers have traditionally used Japanese knotweed (Fallopia japonica) mulch in the cultivation of solanaceous crops in the Nishi-Awa area of Japan, which is a Globally Important Agricultural Heritage Systems site. We have previously evaluated the positive effects of Japanese knotweed mulching on solanaceous crops, such as eggplants, tomato, and potato. In the present study, we observed that the naturally occurring diseases in the solanaceous crops tended to decrease when the knotweed mulching system was adopted, in comparison to when Poaceae mulch was adopted. In eggplants, leaf mold and powdery mildew decreased under Japanese knotweed mulching. We further evaluated the effects of Japanese knotweed mulching by inoculating test plants with Pseudomonas cichorii. We observed suppression of bacterial disease and tomato mosaic virus under Japanese knotweed mulching and following spraying with Japanese knotweed extracts. In addition, disease-resistance genes were expressed at high levels in Arabidopsis thaliana, a model plant, following treatment with Japanese knotweed extracts. The results suggest that Japanese knotweed has potential applications in future sustainable agriculture activities.     

Protecting Important Agricultural Heritage Systems (IAHS) by Industrial Integration Development (IID): Practices from China

With Globally Important Agricultural Heritage Systems (GIAHS) increasing in number around the world, their conservation has become a new international research theme. From the perspective of combining theoretical analyses and practical case applications, this study examines the Important Agricultural Heritage Systems (IAHS) conservation pathways and operation mechanisms through industrial integration development (IID). First, the theoretical framework of IID in IAHS sites was constructed according to the requirements of IAHS conservation, which include analyses of the connotation and basic principles of IID, the necessity of IID for IAHS sites, the resource conditions, and the IID pathways. And then based on the theoretical framework, the IID of Longji Terraces in Guangxi, Honghe Hani Rice Terraces System in Yunnan (HHRTS), Aohan Dryland Farming System in Inner Mongolia (ADFS), and Huzhou Mulberry-dyke & Fish-pond System (HMFS) in Zhejiang are analyzed systematically. The main finding is that IID is an effective pathway for IAHS conservation. However, the IID in IAHS sites must stress the ecological and cultural values of the resources; IID should be based on local resource advantages; and IID should attach importance to the combination of different policies and coordination between different stakeholders.     

The Evaluation of Food and Livelihood Security in a Globally Important Agricultural Heritage Systems (GIAHS) Site

Based on the basic selection criteria of Globally Important Agricultural Heritage Systems (GIAHS) and food and livelihood security research trends, this paper established an evaluation framework and indicator system for food and livelihood security in GIAHS and selected the first GIAHS site in the Qinghai-Tibet Plateau as a case for empirical evaluation. The results demonstrate that the food and livelihood security of farmers at this site was at a medium level, with an average evaluation value of 2.91, which still lagged behind the level of better food and livelihood security. Specifically, the average values of farmers’ evaluation of food security and livelihood security were 1.43 and 1.48, respectively, which show that farmers’ food security in the study area was at a medium level and that of livelihood security was relatively good. Simultaneously, the more simple a farmers’ economic activities (i.e., agriculture-oriented economic activities or non-agriculture-oriented economic activities), the worse their food and livelihood security; while the more diversified the economic activities (i.e., engaged in part-time economic activities), the better the food and livelihood security.     

全球重要农业文化遗产(GIAHS)经济评估概念框架:以中国稻鱼共生系统为例（英文）

全球重要农业文化遗产(GIAHS)项目是2002年由联合国粮农组织(FAO)发起,旨在建立全球重要农业文化遗产及其有关的景观、生物多样性、知识和文化保护体系,并在世界范围内得到认可与保护,使之成为可持续管理的基础。农业文化遗产地往往被认为比非遗产地更具经济价值,但目前还没有经济学分析来证明这一点,也没有任何针对农业文化遗产地的复杂的经济性能标准来长期监测其经济功能。本研究的目的在于建立一个经济评价方法,可用于遗产地与非遗产地之间比较。为此,本文选择了成本效益分析(CBA)方法。鉴于数据可得性的限制,经济分析的框架应该包括分析的方向、假设和数据要求,由此指导未来对GIAHS的经济评价。本研究选择中国青田稻鱼共生系统作为案例,根据数据可得性并针对不同活动(旅游,国内和国际市场的销售产品)以及相似系统间比较进行计算。     

Conceptual Framework for Key Element Identification in Important Agricultural Heritage Systems (IAHS): Case of Honghe Hani Rice Terraces System in China

With the continuous emergence of global development problems, the dynamic conservation and sustainable development of Important Agricultural Heritage Systems (IAHS) have been assigned greater importance. However, due to the complex structure, multi-component, dynamic, and open characteristics of IAHS, there are neglected problems which need to be solved in conservation practice, such as component element ambiguity, obscurity of the conservation redline, etc. This study defined the concept of key elements (KE) of IAHS, put forward a conceptual framework of KE identification, conducted empirical research by taking Honghe County of Honghe Hani Rice Terraces System (HHRTS) as an example and analyzed the level of recognition motivations for different stakeholder groups. The following conclusions were drawn: 1) The KE of HHRTS are grain crops, rice species biodiversity, terrace construction and maintenance technique, Hani traditional festivals, Hani traditional foods, and virgin forest; 2) The reasons behind the KE priorities of farmers, businessmen and tourists were at the micro level, the reasons of officers were at the middle level and the reasons of researchers were at the macro level. The empirical study conducted in HHRTS showed that the proposed conceptual framework could identify KE of IAHS effectively, and provided a theoretical perspective for the structuring of and essential need for IAHS research. Moreover, the KE recognition levels of different stakeholder groups reflected their potential action strategies. We should focus on the coherence of policies and measures in both the microscale and macroscale to balance the diversified demands of stakeholders, and to stimulate their enthusiasm for participation in the conservation in order to improve the management level of IAHS sites.
