基于生态系统服务价值评估的我国集中连片重点贫困区生态补偿研究

本文基于2010年Landsat TM/ETM+数据,HJ-1卫星CCD数据,MODIS17A3净初级生产力数据和土壤,气候的地面实测数据,采用以生态系统服务价值为基础的区域差异化生态补偿估算方法,对中国14个集中连片贫困区生态补偿标准进行了估算.研究结果表明,2010年中国14个集中连片贫困区生态系统服务总价值达20 627.4亿元,与同年该区域GDP总量 22 096.2亿元大体相当,在南疆三地州,四省藏区和西藏片区3个西部片区,每年的生态系统服务总价值为GDP总量的2-12倍,这对保障中国生态安全具有重要意义.在14个集中连片特困区,生态补偿所需资金每年约为1971.0亿元,平均每县约为2.9亿元.目前,国家给予的生态补偿资金与此相比严重不足,即使是接受一般性财政转移支付的国家重点生态功能区,其各县市平均每年接受补偿资金也仅为0.94亿元,不到所需金额的1/3.生态补偿资金不足不但给各片区扶贫工作带来巨大压力,也带来了严重的生态风险.因此,生态补偿资金增量的投入可能是解决集中连片特困区贫困问题关键所在,在此增量补偿资金基础上,集中连片特困区可建立以国家购买生态产品为主,开发性扶贫增长为辅的可持续经济增长模式,这可能是彻底解决中国集中连片特困地区贫困问题的基本途径.     

Policy and Practice Progress of Watershed Eco-compensation in China

The ecological protection of the watersheds in China is being confronted with a lot of problems such as soil and water erosion, water pollution at present. Therefore watershed eco-compensation is becoming a question of common interest. Based on the analyses of the major problems and their origins in the watershed protection in China, the paper discusses the concerned policies including relative rules and laws, financial policies and water right transaction policies. Simultaneously the paper reviews the practices carried out in China, including the ecological construction project in the western China, the trans-provincial eco-compensation practice and the small watershed eco-compensation practice. According to the present situation of eco-compensation practices and the future policy requirement, this paper finally puts forward four key problems to be solved in the watershed eco-compensation of China in the future.     

Regional distribution and sustainable development strategy of mineral resources in China

This paper summarizes the distribution and production layout of the major mineral resources in China,including coal,iron ore,copper and bauxite,from a national perspective.It also identifies the incompatibility between the mineral resources distribution and regional economic development.Significant issues with China’s mineral resource industry cause challenges for the sustainable development of both the mining industry and the national socio-economy.The sustainability of regional mineral resources and the environmental pollution by mining in the western China were also analyzed.Results show that the distribution of China’s mineral resources is misaligned with its regional layout of economic development.China’s mineral resources have been over-exploited,and the mineral resources production in the eastern China is unsustainable.The continuously expanding production of mineral resources in the western China has heavily endangered the ecological environment.We propose strategies to boost the sustainable development of mineral resources,including measures to accelerate economic development and enhance the sustainability of domestic mineral resources.We also offer suggestions for scientifically planning the mineral resource prospecting and exploitation and regional economic layout,as well as for proactively undertaking industry transfer in the eastern China and raising the environmental benchmark requirements for the mineral industry in the central and western China.     

区域可持续发展的指标、标准和限制

世界各国包括俄罗斯在内已经出版了大量关于可持续发展的理论研究方面的书籍。但总体而言,在不同结构层次(全球、国家、区域和地方)的可持续发展模型中,区域水平上的模型可能是最复杂和最基础的层次。本文在构建可持续发展模型的框架下,给出了一个区域经济、社会和生态发展的指标体系、标准和限制,并建立了一套评价区域自然资源潜力及其动态变化的方法。首先,对区域层次上达到可持续发展的条件和内容进行分析。其次,给出一个区域经济、社会和生态发展的框架。其中区域发展的经济质量是指其自身资源状况所带来的区域发展能力;区域发展的社会质量是指由区域的人口潜力和社会结构所带来的在一个长时期内稳定的区域人口以及由此提供的高标准生活质量的能力;区域发展的生态质量是指在一个长时期内区域保持其自然资源潜力和高质量环境的能力。区域可持续发展是在一个长时期内(10年)区域高质量的发展,在区域发展质量水平上进行可持续性和平衡性的评价是必要的,为此建立三者之间适当的比例关系。第三,为反映区域间发展的差异,对区域内的经济、社会等进行自然-经济区划以及对每个分区进行相应的指标的计算。这些绝对和相对的可持续发展比率反映了一定时期内实际的状态距离标准值的程度,刻画了区域发展的质量特征。如果这种比率发生变化,或者相对标准值发生动态改变,那么这些比率就可以评估发展的稳定性,以及同时反映了区域发展在质量上的提高或者降低。第四,区域自然资源潜力及其动态变化的评价。第一步是进行局部自然资源分区和把国土自然资源系统作为最复杂的评价对象进行整体考虑。然后对每一个自然资源系统进行动态平衡的计算(这种平衡反映了自然资源的动态和状态)。自然资源潜在的变化可以用实际的或者预测的数据进行计算。

The regional development in a multi-cultural background

China is a country with many nationalities. Each of them has formed its own special culture, which is different from the mainstream of majority Han nationality, by adapting to geo-environment during history. Due to different backgrounds, the regional developmental model of minorities in the western China is different from the Han nationality and western countries. Combining a knowledge-based civilization and sustainable development, the minority areas can seek the systematic integration of culture-economy-ecology. Based on this, the paper suggests that the minority areas in western China should take the way of emphasizing developmental quality rather than developmental quantity for a harmonious system of culture-economy-ecology. Some approaches for developing minority areas in western China have been put foreword. Foundation item: Under the auspices of the National Natural Science Foundation of China (No. 49261001).

STUDY ON URBAN LAND SAVING IN THE ECONOMICDEVELOPED COASTAL REGION OF CHINA

In China, the land resource per person is poor withregard to the huge number of population. According tothe recent data from the National Land Bureau, theaverage land per person is 0. 11 ha, much less than0. 25 ha, the average land per person in the world(FAN, 1997). On the other hand, a large scale ofrural land is to be transmitted into urban land upon thefast proceeding of urbanization. At present, the urbanpopulation occupies about 30% of the total in China.

A study on marine region carrying capacity and eco-compensation

With the using up of land resources, people are beginning to pay attention to the exploitation of the ocean and the use of marine resources is becoming more and more intense. Whether and how the ocean can be sustainably exploited as it is being exploited is an academic hot topic. This question is addressed in this paper based on the theories of carrying capacity of a marine region and marine eco-compensation, and the amount of the loss is calculated by the method of Time Value of Capital. This thesis covers the study of eco-compensation between two specific subjects with clear compensation objects, and as a defined approach and standard, the proposed method has good operability and positive practical significance in the good use of the ocean.     

Regional ecological security and diagnosis of obstacle factors in underdeveloped regions: a case study in Yunnan Province,China

In order to clarify regional ecological security status and formation mechanism of regional ecological security barriers in underdeveloped regions of China, we took Yunnan province as a case to evaluate its regional ecological security by using entropy matter-element model, comprehensive index and GIS spatial method, and we diagnosed its obstacle factors through obstacle degree model. We found a low overall level of regional ecological security in Yunnan. Only Kunming fell into the good level, 68% of the regions were below the critical safe level. For the vast majority of regions in Yunnan, their regional ecological security was unstable. The indexes related to per capita resources, geological and topography environment, economic, and technology were at the unsafe or dangerous level. The indexes related to urban expansion, level of income, cultivated land quality were at the level of critical safety. The indexes concerning urban management capacity, air quality and water environment were at the good or ideal level. Yunnan’s regional ecological security was not good due to natural obstructive environment itself, simultaneously lower backward economic and social level restricted the ability of ecological security response to manage ragile ecological environment. The results of the composite index were roughly consistent with those of the entropy weight matter-element model. The mean values of the classification index, from high to low, were: the state index > the response index > the pressure index. The state index and the response index had a significant mutual promotion to each other. The regions with good composite index, state index and response index mainly distributed in the central regions of Yunnan Province. Spatial autocorrelation of regional ecological security level in Yunnan was not obvious. Water resources, economic and social development were main obstacle factors of the regional ecological security. When distinguishing with obstacle type, Kunming belonged to natural ecological environment barrier type, while other regions belonged to economic and social barrier type.     

Evaluation of the production-living-ecology space function suitability of Pingshan County in the Taihang mountainous area,China

A rational utilization of land is a matter of importance in sustainable development of mountainous area. The land function in mountainous areas has a close connection with space structure of ecology, production and living. To promote a harmonious development of the relationship between people and nature in mountainous areas, it is necessary to coordinate their relationships of space functions. Suitability evaluation of basic unit function associated with multi-scale space analysis is a prerequisite to a reasonable optimization of land function structure. In this study, an optimized evaluation index system of combination functions was introduced into the assessment of ecological spatial functional suitability in ecological fragile regions by adding three indicators, namely, soil erosion sensitivity, landscape ecological risk and ecological sensitivity. The principle of "taking high"(referred to a function with high suitability to be regarded as the main function of an evaluation unit) and ecological priority(referred to the case, supposing the suitability of a unit's three functions is consistent, the main function is determined to be the ecological function) were used to determine the main function of an evaluation unit. Pingshan County, China, located at the eastern foot of the Taihang Mountain, was targeted in this case study. The production-livingecology space(PLES) function in Pingshan was identified by applying our improved valuation indexes. Further, the functional suitability distribution of the combination of elements was obtained by using overlapping comprehensive analysis method, considering the tradeoff of the functional suitability of combination elements. The regions suitable for production/living were distributed in relatively flat piedmont plains, whereas the regions suitable for ecology were distributed in the mountain areas of middle and low altitudes. Therefore, to maintain a sustainable development in mountainous areas, an improved scheme of development for Pingshan should be to delineate ecologically fragile areas, to build ecological industrial parks near existing scenic spots, to protect basic agricultural production areas, and to increase investment in science and technology, including reasonable ecological compensation. This study can provide reference for the planning of sustainable development in the Taihang Mountain area and similar regions.

The “Valley Economy” Model of Regional Development: A Case Study of Mountain Areas in Beijing,Northern China

A case study is presented of a regional development model for valley economies in the mountain areas of Beijing, China. The nature and framework of the valley economy model are described and the development of the model, which is specific to the mountain areas of Beijing, is analyzed. Five different valley economy models applied in the Beijing mountain areas are compared. The major purpose of the valley economy model is to develop the regional economy, including the selection of appropriate industries, the allocation of industrial space, the establishment of supply chains and the integration of various industries. Pilot experiments using the valley economy model have been conducted in seven counties（districts） in Beijing： Pinggu, Huairou, Changping, Mentougou, and Fangshan districts, and Yanqing and Miyun counties. Five models for developing the Beijing mountain areas have been explored, including： creative cultural industries, characteristic industry clusters, the promotion of large tourist areas, natural scenic tourism and folk cultural tourism. Each model has its own unique features and potential to help in the regional development of mountain areas.

基于SOFM网络的景观功能分类——以北京及周边地区为例

 景观多功能性是景观生态学研究的热点领域,需要一种既能体现景观多功能整体性,又能表征各功能间独立性的表达方法。本文以北京及其周边地区为研究区,以500m栅格为最小评价单元,使用空间化的统计数据表征物质生产功能,使用植被生物量与土壤含碳量之和表征碳汇功能,使用潜在水土流失量与实际水土流失量的差值表征土壤保持功能,使用生态系统服务功能的评估结果表征生境维持功能,使用人口空间化数据表征居住功能。在计算5种景观功能强度后,通过自组织特征映射模型将土地栅格进行聚类分析。研究结果表明:景观功能强度具有空间异质性。景观功能强度可分为以农地为优势景观,以物质生产为主要功能的农业功能区域;以农地和城市用地为优势景观,以居住和碳汇为主要功能的城市功能区域;以林草地为优势景观,以土壤保持和生境维持为主要功能的生态功能区域;以及优势景观不明显,各项功能均衡发展的过渡功能区域4类。该分类方法既可较好地表达多功能景观的功能分异和空间分异,又能为其研究土地利用和生态管理实践提供理论依据。     

Ecosystem Health: Assessment Framework,Spatial Evolution,and Regional Optimization in Southwest China

Regional ecological health,the core of comprehensive ecosystem assessments,is an important foundation for regional exploration,environmental conservation,and sustainable development.The mountainous areas in southwest China are backward in economy,but industrialization and urbanization have been rapid in recent years.This study assessed the ecosystem health of the Sichuan and Yunnan provinces in China using a pressure-state-response(PSR)model.Spatiotemporal patterns of regional ecosystem health were analyzed from 2000 to 2016,including overall characteristics as well as local characteristics.Ecosystem health in most regions was improved over time(Y=0.0058 X–11.0132,R2=0.95,P<0.001),and areas with poorer ecosystem health decreased from half to one-third of the total area.Analysis of the primacy ratio and the variation coefficient confirmed that the gap in health scores between regions has gradually expanded since 2007,but there are more high quality regions overall(Z of Moran’s index<1.96,P>0.05).Overall,the regional ecosystems to the east of the Hu line-an imaginary line dividing east and west China into roughly equivalent parts-were healthier than those to the west.The pressure and state scores of ecosystems were determined by physiographic condition,and the response scores by government policies and social concern.The spatiotemporal patterns of ecosystem health were dominated to a greater extent by natural than anthropogenic factors,which explains why the shift in the patterns aligned with the direction of the Hu line.Dividing regions into key management areas based on natural geographical conditions and socioeconomic development could contribute to the formulation of a reasonable ecological and environmental protection policy,guaranteeing ecosystem services in the long run.     

Evaluation of water resources conserved by forests in the Hani rice terraces system of Honghe County,Yunnan, China: an application of the fuzzy comprehensive evaluation model

The Hani Rice Terraces System, based on gravity-flow irrigation, is one of the Globally Important Agricultural Heritage Systems(GIAHS) pilot sites selected by FAO in 2010. The water resource plays an important role in the sustainable development of this system. The value of water conserved by the forest is influenced by natural, economic and social factors. In this paper, the water quality, per capita water resources, per capita GDP and population density are chosen as indices to construct an index system for a comprehensive evaluation of water resources value. The weights of these indices are 0.443, 0.31, 0.141 and 0.106 respectively, which are determined by the analytic hierarchy process(AHP) method. The water resources value has been assessed by the fuzzy comprehensive evaluation model. The results show that the water resources value in the Hani Rice Terraces System is 4.25 RMB/m~3. Evaluating the value of water resources in the Hani Rice Terraces System can provide a reference for ecological compensation, for raising public awareness of the importance of protecting the system, and ultimately achieving its sustainable development.
