“一带一路”倡议的理论论述——从新自由主义全球化到包容性全球化（英文）

An international consensus is emerging around the Belt and Road Initiative(BRI) proposed by the Chinese government, with a growing number of countries seeing it as a way of jointly exploring new international economic governance mechanisms. Meanwhile, with the crisis of neo-liberalism, economic globalization has arrived at a crossroad. In particular, incessant voices speak out against globalization, making the quest for a new way of promoting global development a major challenge. In this context, more and more political elites and scholars consider that the BRI opens up a possible new globalization path, amongst which inclusive globalization warrants exploration. On the basis of a brief analysis of the course and mechanism of global economic expansion and the limitations of neo-liberal globalization, along with the putting into practice of the BRI, this paper outlines some of the core features of inclusive globalization, i.e., inclusive growth with effective and efficient government regulation; inclusive infrastructure development; inclusive development paths chosen nationally that suit national conditions; inclusive participation; and cultural inclusiveness. Although these features are not sufficient to characterize fully inclusive globalization, they do identify some directions for future research, and provide elements of a discursive construction of the BRI.     

“一带一路”生态系统服务消耗格局与演变（英文）

生态系统服务消耗研究对于生态系统保护与可持续发展具有重要意义,已成为生态学研究的热点。本研究基于FAOSTAT数据,以生物量消耗为主要指标,动态研究"一带一路"沿线全域及分区生态消耗格局、构成及其演变规律,揭示该区域生态消耗模式主要类型、分布格局与演变态势。得出以下结论:(1)全域生态消耗主要来自农田消耗,其次为草地消耗;生态消耗整体呈波动增加,消耗总量从2000年的12911.89Tg增加到2016年的16810.00Tg,年人均消耗量从2000年的332.28万g增加到2016年的363.92万g。(2)生态消耗及其变化在国家间、分区间及生态系统类型间差异显著,人均生态消耗以蒙古国最高,分区尺度以中东欧最高,东南亚最低,这是区域资源禀赋、生态消耗模式及生活水平等共同作用的结果。(3)农田消耗为主是该区域主导生态消耗模式,约占总面积的76.71%,其次为农草消耗,约占总面积的19.0%,仅少数国家为草地消耗为主、森林消耗为主或农林草消耗并重,这可能与该区域人口密度大且多为发展中国家有关。因此该区域在依据自身资源优势发展农林牧产业时,应扩大贸易,互惠共赢,优化生态消耗模式,促进区域社会、经济与生态可持续发展。     

“一带一路”国家贸易关系结构与演进（英文）

Trade facilitation is one of the five main agendas of the Belt and Road Initiative(BRI). Social network analysis has helped understand the complexity of trade networks, but existing studies tend to overlook the fact that not all bilateral trade relations are equally important to a country. To fill this gap in the literature, this paper focuses on the top 2 trade relations networks to illuminate the structure and evolution of BR trade relations, the relative positions of different countries, and changes in the composition of trade communities(e.g., the community leaders) and the changing patterns of trade between them. We find rich dynamics over time both inter-and intra-communities. The overall international trade networks of BR countries experienced a leadership change from Russia to China on one hand, some temporary communities experienced emergence, disappearance(e.g. the Kuwait-and Thailand-led communities) or reemergence(e.g. Poland-led community), and a community membership was generally consistent on the other hand. Since the future impacts of China's BRI will depend on the degree of integration of the connected regions, some countries with stable and high centrality indices(e.g. Russia, Singapore, Serbia, Greece, Turkey, Iran, Poland, Hungary and Romania) could be selected by China as strategic regional partners, and countries with a strategically important geographical position but weak trade links(e.g. Myanmar, Pakistan, and Belarus) should be prioritized.     

基于可持续发展目标（SDGs）的“一带一路”农业可持续性分析（英文）

"一带一路"国家需要在顶层谋划方面做出努力,方能确保农业的可持续发展。而这需要对"一带一路"沿线国家农业可持续性有一个准确的评判。本文在"一带一路"可持续农业概念认识与可持续发展目标(SDGs)中农业目标解读的基础上,借助统计回归分析、趋势预测等方法,预测了2030年"一带一路"沿线国家经济增长和城镇化等社会经济发展的趋势,以及这些发展趋势相应地对农业资源环境的冲击。结果表明,"一带一路"沿线国家农业资源环境前景不容乐观,且难以支撑起该地区未来对粮食安全需求的保障,只有采用积极应对政策和措施,并在战略上进行规划和布局,才能确保该地区2030年粮食安全这一农业可持续发展目标的实现。为此,"一带一路"沿线国家需要从构建农业合作平台、设立专项基金,以及创新农业合作模式等三个方面进行战略合作,推动"一带一路"沿线国家的农业实现可持续发展。     

“一带一路”沿线区域耕地格局变化（英文）

The Belt and Road Initiative(BRI)–a development strategy proposed by China – provides unprecedented opportunities for multi-dimensional communication and cooperation across Asia,Africa and Europe.In this study,we analyse the spatio-temporal changes in cultivated land in the BRI countries(64 in total) to better understand the land use status of China along with its periphery for targeting specific collaboration.We apply FAO statistics and Globe Land30(the world's finest land cover data at a 30-m resolution),and develop three indicator groups(namely quantity,conversion,and utilization degree) for the analysis.The results show that cultivated land area in the BRI region increased 3.73×10~4 km~2 between 2000 and 2010.The increased cultivated land was mainly found in Central and Eastern Europe and Southeast Asia,while the decreased cultivated land was mostly concentrated in China.Russia ranks first with an increase of 1.59×10~4 km~2 cultivated land area,followed by Hungary(0.66×10~4 km~2) and India(0.57×10~4 km`2).China decreased 1.95×10~4 km~2 cultivated land area,followed by Bangladesh(–0.22×10~4 km~2) and Thailand(–0.22×10~4 km~2).Cultivated land was mainly transferred to/from forest,grassland,artificial surfaces and bare land,and transfer types in different regions have different characteristics:while large amount of cultivated land in China was converted to artificial surfaces,considerable forest was converted to cultivated land in Southeast Asia.The increase of multi-cropping index dominated the region except the Central and Eastern Europe,while the increase of fragmentation index was prevailing in the region except for a few South Asian countries.Our results indicate that the negative consequence of cultivated land loss in China might be underestimated by the domestic-focused studies,as none of its close neighbours experienced such obvious cultivated land losses.Nevertheless,the increased cultivated land area in Southeast Asia and the extensive cultivated land use in Ukraine and Russia imply that the regional food production would be greatly improved if China' "Go Out policy" would help those countries to intensify their cultivated land use.     

“一带一路”地区的生态承载力与绿色发展（英文）

20世纪70年代以来,全球性资源危机、环境污染和生态退化问题凸显,增长的极限始终是一个重要的理论与政策问题。承载力评价、预警与调控在自然资源利用、环境管理和生态保护中都有巨大的应用潜力。本文梳理了承载力演变历程及生态承载力的概念,将已有生态承载力评价方法归纳为生态足迹法、综合指标体系法、生态系统服务法、净初级生产力人类占用分析法等4类。分析了当前生态承载力研究中问题,并展望了未来发展趋势。结合"一带一路"地区的生态承载力与绿色发展专辑,从生态承载力评价方法与应用、生态系统服务供给与消费、资源利用与环境变化等方面对"一带一路"地区的生态承载力研究进展做了介绍。建议"一带一路"地区生态承载力研究应深入刻画生态承载力的时空异质性及动态变化,模拟生态过程与人类活动的相互作用,将气候变化、人类活动及生态产品与服务流等因素纳入生态承载力评价体系与模型中,提高评价结果的精度和可靠性,提升生态承载力研究对相关决策的支撑能力。     

“一带一路”陆域地理格局与环境变化风险（英文）

Building the Belt and Road is initiatives of China to promote win-win international cooperation in the new era, aiming at green, health, intellect and peace and the joint development with people of the countries along the route. Systematic analysis on environmental characteristics, evolutionary tendency and future risks are certainly the scientific fundamentals of sustainable development for the Belt and Road construction. Applied remote sensing monitoring, statistical analysis, this paper investigates the regional characteristics of climate, topography, soil, hydrology, vegetation cover and terrestrial ecosystems production, as well as socio-economic conditions. Based on the regional characteristics, the Belt and Road is divided into 9 sub-regions: Central and Eastern Europe sub-region with cold and humid climate, Mongolia and Russia sub-region with cold and arid climate, Central and West Asia arid sub-region, Southeast Asia sub-region with warm and humid climate, Pakistan arid sub-region, Bangladesh-India-Myanmar sub-region with warm and humid climate, Eastern China monsoon sub-region, Northwest China arid sub-region and Tibetan Plateau sub-region. Combining modeling simulation with scenario projections, natural disaster assessment methodology is used to assess the risk of extreme events including heat waves, droughts and floods in the coming 30 years(2021–2050). Results show that, on the basis of the regional framework, the western Eurasia would be a warming trend; both sides of Qinghai-Tibet Plateau in high temperature and heat waves risk; Central and Eastern Europe sub-region with cold and humid climate in high drought risk; Bangladesh-India-Myanmar sub-region with warm and humid climate as well as Eastern China in high risk of flooding.     

“一带一路”倡议下东北地区粮食产业转型升级路径

采用逻辑思辨的方法分析了"一带一路"倡议下东北地区粮食产业转型升级的重要价值与驱动,在"一带一路"倡议下东北地区粮食产业发展问题研判的基础上提出了其粮食产业转型升级的优化路径。主要结论如下:①新结构经济学通过要素禀赋的内生驱动,产业梯度转移通过竞合效应与传导机制,顺向投资通过效率寻求型顺向投资、市场寻求型顺向投资和资源寻求型顺向投资,进出口贸易通过贸易自由化竞争效应、贸易结构先导效应、市场规模扩张效应共同驱动粮食产业优化升级;②东北地区粮食产业发展面临粮食增长不稳定、增速不可持续性、种植结构需要继续优化以及种植质量和农产品效益亟需提升的问题;③未来东北地区需要以创新驱动为动力、以粮食产业链价值增值为着力点、以顺向投资为重要途径,以进出口贸易为突破口推动粮食产业转型升级。     

“一带一路”沿线地区隐含碳流动研究（英文）

In the past few decades, economic globalization has driven rapid growth of cross-border trade and a new international division of labor, leading to increasing inter-country embodied carbon flows. Multi-region input-output(MRIO) analysis is used to identify embodied carbon flows between major world regions, including seven regions along the Belt and Road(BR), and the spatial distribution of production-and consumption-based carbon intensities. The results show that current embodied carbon flows are virtually all from BR regions to developed countries, with more than 95% of world net embodied carbon exports coming from BR regions. Consumption in the United States and European Union countries induce about 30% of the carbon emissions in most BR regions, indicating that the former bear a high proportion of consumers' responsibility for the carbon emitted in the latter. For this reason, measuring environmental responsibilities from consumption rather than a production-based perspective is more equitable, while developing countries should be given a louder voice in the construction through dialogue and cooperation, in part in the context of the Belt and Road Initiative, of an inclusive global climate governance system.     

中国“一带一路”倡议的包容性开放效应——基于“一带一路”沿线国家HDI指数的经验分析

与以往发达国家主导和推动的经济全球化不同,中国“一带一路”倡议由于秉持着人类命运共同体先进理念,不仅为更多发展中国家融入全球价值链分工提供了更多机会,而且力图改善其分工地位,从而推动经济全球化朝着更加具有包容性开放的方向发展,让开放发展的成果能够更多地惠及世界各国尤其是其他发展中国家。在理论分析基础上,以人类发展指数（HDI）作为包容性开放效应的表征变量,基于2010—2019年ADBMRIO数据库中60个国家的经验数据,采用双重差分模型进行实证分析及稳健性检验,分析“一带一路”倡议的包容性开放效应。结果表明,“一带一路”倡议显著促进了沿线国家HDI提升,表现出较好的包容性开放特征,并且上述效应主要通过提升沿线国家全球价值链参与度和改善分工地位2个作用机制产生,理论假说得到了较好的逻辑一致性计量检验结果。据此可见,秉持人类命运共同体先进理念的“一带一路”倡议,不仅有着坚实的理论基础,而且实践经验证明中国已经走在推动包容性开放道路上,包容性开放效应在“一带一路”沿线国家初步显现。     

“一带一路”倡议下中国与中亚合作的战略支点选择

中亚在“一带一路”倡议中具有重要地缘价值,而中国与中亚的合作需以战略支点为依托。相关研究多关注国家尺度和定性方法,较少深入到对区域尺度战略支点及其空间结构的分析中,可能导致支点范围较大、针对性较弱。故本文主要从区域尺度入手,基于对各类空间要素的综合评价,对战略支点的空间结构进行分析。研究表明,乌鲁木齐等中国城市、阿拉木图等中亚城市以及霍尔果斯等边境口岸在各类节点中具有综合优势。基于可达性和城市网络分析结果,结合中国与中亚合作现状,可将“乌鲁木齐-阿拉木图经济走廊”作为战略支点,采取“两核四轴四带”的空间结构。创新点在于从区域尺度认识战略支点并分析其空间结构,有利于通过尺度上推进一步撬动高尺度合作。     

“一带一路”贸易网络及其与全球贸易网络的拓扑关系分析（英文）

Unimpeded trade is one of the cooperation priorities in the Belt and Road Initiative proposed by China. On 15 May 2017, the Joint Communique of the Leaders Roundtable of the Belt and Road Forum for International Cooperation reaffirmed the participants' shared commitment to build an open economy and ensure free and inclusive trade. The Belt and Road Initiative(BRI) is not only China's new action to drive its open and global development, but also a platform for an increasing number of countries to explore free and inclusive trade and promote a universal, rule-based, open, non-discriminatory, and equitable multilateral trade system. It is therefore important to examine the topological relationship between the BRI and global trade networks. More specifically, this article first analyzes the community structure of trade networks using a community detection algorithm, and then estimates the topological relationship between different trade communities. The findings of this article are as follows. First, this research identified three trade communities and two sub-communities in the BRI trade network, in which China is the core, Russia is the sub-core of the biggest trade community, and India, United Arab Emirates, and Saudi Arabia are cores of the second trade community(South Asia-West Asia). Second, it identified five trade communities in the global trade network, centred on China, USA, Russia, India-United Arab Emirates, and Germany-Netherlands-France-Britain and other European developed countries. Third, the topological analysis indicated that in the global trade network, most BRI countries are attracted by the core nodes of the BRI regions, such as the China, Russia and India-United Arab Emirates core nodes, and have strong trade contacts with BRI countries. Most Central-East European countries are mainly attracted by Germany-Netherlands-France-Britain and other developed European countries with a low penetration of BRI trade. Although some Southeast Asian countries are incorporated into the Asia-Australia-South Africa community with China as the core, they still need to strengthen trade linkages with BRI countries.     

安伊高铁项目与一带一路倡议——有效协商、制度协调与区域发展（英文）

This article contributes to a small but growing body of multi-sited and multi-scalar research on the Belt and Road Initiative. We focus on relations at the national, regional and international scales, and present original research from China and Turkey, to show how the Istanbul-Ankara high-speed railway has served as a testing ground for China's Belt and Road Initiative(BRI). Its construction was initially funded by the European Investment Bank, but it is now part of the backbone of the Turkish Government's Middle Corridor plan which enhances west-east connectivity and integration with the Caucasus and Central Asia. We show that in contrast to multinational corporations from the OECD that seek to remain footloose, Chinese state-owned enterprises(SOEs) seek to adapt to, apprehend and ultimately shape local institutions. In the case of Turkey this proved difficult given its institutional alignment with the European Union. Thus, while the railway project was completed successfully by a consortium led by a Chinese SOE, Turkey's dynamic and complex regulatory environment discourages Chinese SOEs in the infrastructure sector. We conclude that the Turkish and Chinese governments are currently pursuing complementary territorial visions yet their cooperation is project-based and pragmatic.     

基于虚拟水理论的“一带一路”沿线国家水资源承载力分析（英文）

"一带一路"沿线国家大多面临水资源短缺情况,水资源能否支撑其经济社会发展关系到"一带一路"倡议的顺利实施。本文构建水资源承载力评价指标体系,对各评价指标进行分级和权重分配,并对沿线65个国家的水资源承载指标进行了计算,同时结合虚拟水理论,分析中国重点大宗类农产品国际贸易的净进口虚拟水含量。对沿线一半以上的国家来说,他们的水资源将无法支撑他们的经济发展,而经济发展是实现该倡议目标所必需的。中国作为水资源承载力不足的国家,在虚拟水贸易中属于虚拟水净进口国家,虚拟水贸易有利于中国提高水资源支撑能力,对未来保障中国水资源安全、食物安全都有积极意义。     

“一带一路”倡议下中国对东盟研究的智力支持

东盟作为“21世纪海上丝绸之路”的重要枢纽,在“一带一路”倡议中扮演着愈加重要的角色。通过梳理东盟研究智力支持与“一带一路”倡议“五通”的作用机理,运用文献计量及空间分析的方法,分别对东盟国家的研究机构、研究人才、研究方法、研究成果、语言专业培养以及联系机制等进行多角度解析,旨在揭示“一带一路”倡议下东盟研究的现状和问题,并提出相应对策措施。结果表明,东盟研究智力支持现状与问题如下：1）面向东盟的智力支持机构数量少、基础不足、地域分布不均;2）智力支持人才建设不足,以国内平台为主,呈现“相对集中,宏观分散”的特征;3）智力支持方法与成果,关注面相对窄、学科分布不均衡、定量方法运用较少;4）语言智力支持方面,非通用语学科建设不足、语言学术衔接不畅、语言人才培养较少;5）智力支持联系机制缺乏平台建设,受地缘环境主导思维影响大等。立足于东盟研究智力支持的现状与问题,依次提出：整合优化组织机构、重视人才培养与就业相对接、打破学科壁垒,优化成果质量、加强非通用语人才培养与衔接、建设有效沟通平台等相应针对性对策建议。     

“一带一路”建设模式研究——基于制度与文化视角（英文）

There is a gap between the great vision and high-quality targets of the Belt and Road Initiative(BRI) and Western recognition of them, which challenges Chinese and Western scholars. This gap should be narrowed by conducting in-depth case studies and comparative studies at the project level. In recent years, the international academic community has paid increasing attention to Chinese outward foreign direct investment(FDI), but Belt and Road construction is much broader in scope, comprising not only FDI projects but also China-financed projects and emerging mixed projects. Our investigation, observation, and examination of the BRI projects find that compared to their Western counterparts, Chinese enterprises have less experience in doing business in other countries and often pay less attention to institutional and cultural differences between China and the host countries. Thus, revisiting the institutional and cultural turn in economic geography and employing its ideas to analyze the BRI projects and summarize their construction modes may contribute to the development of both economic geography and the BRI. This paper first briefly reviews the background and research trends of the institutional and cultural turn and then summarizes three major modes of Belt and Road construction, namely, EPC(Engineering Procurement Construction)-based projects, concession-based projects, and FDI; finally, it draws on the institutional and cultural turn to classify the BRI projects according to the two indicators of "Breadth and Depth of Territorial Embeddedness" and "Destructive Effect of a Project and/or Technology" into four types: transformative, supportive, ordinary projects and overseas industrial cooperation parks. Different institutional and cultural sensitivity can be observed for each type of project. The preliminary theorization proposed in this paper may offer a potential framework for further research on the BRI.     

“一带一路”倡议下中国陆海运输的空间竞合格局

在“一带一路”倡议全面实施的背景下,中欧班列的建设明显提升了中国与欧洲的陆上集装箱运输量,但陆运较之于海运是否具有比较优势以及形成怎样的空间竞合格局,是当前非常值得研究的经济地理课题。采用中欧班列、中国铁路货物运费及海运数据,将不同价值的集装箱在时间成本中产生的利息纳入运费计算,构建陆海运输平衡线与集装箱价值平衡点模型,刻画中国大陆至欧洲的陆海运输空间格局。研究表明：不考虑时间成本时,陆海运输平衡线位于西北地区,考虑时间成本后,平衡线向东南沿海迁移;以通辽—沈阳—北京—石家庄—襄阳—重庆—丽江—保山为界,形成陆运优势片（阿拉山口区、满洲里区和二连浩特区）和海运优势片（环渤海区、长三角区和珠三角区）,构成“两片六区”格局;考虑未来陆路运价可能降低,以南通—南京—南昌—岳阳—贵阳—昆明—普洱为界可以构建“两片五区”新的陆海运输格局。在此基础上,中国大陆至欧洲的集装箱陆海运输竞合格局可进一步划分为面积占比70.9%、12.9%和16.2%的陆运区、海运区及陆海区。研究说明可以通过陆运运价的调整以及货运集散地的优化布局,来获取中国大陆所需要的陆海平衡线分布,从而谋划基于陆海竞合基础上的中欧集装箱运输的最优联动格局。     

基于生态承载力视角的中国与“一带一路”国家农牧产品贸易流特征（英文）

在全球生态超载的背景下,贸易成为弥补国家或区域生态赤字的重要手段之一。本研究以"一带一路"国家为研究区,分析了中国与"一带一路"沿线国家(地区)的生态承载力与生态足迹变化特征,从生态承载力视角探究了贸易流动特点,采用虚拟土地的进出口量评估贸易对中国耕地与牧草地的资源缺口的弥补作用。主要结论有:1)2005–2014年绝大多数"一带一路"国家超载程度增大。中国生态承载力占比最大的是耕地,生态足迹以碳足迹为主。2)中国大陆的农牧产品贸易流具有进口量增大、出口量降低的趋势,加大了对特定区域的依赖。3)2005–2014年,中国大陆对"一带一路"沿线国家(地区)谷物和油料作物贸易一般为净进口,与"一带一路"沿线国家(地区)的谷物贸易所占比重逐渐提高,油料作物贸易比重迅速降低。4)进口贸易在一定程度上缓解了生态赤字,本研究选择的代表性农牧产品分别弥补了中国1.03倍的耕地赤字和0.65倍的草地赤字。本研究深化了对中国与"一带一路"国家(地区)土地资源利用与农牧产品国际贸易关系的认识,可为减少生态赤字、优化土地资源利用及推进中国与"一带一路"沿线国家(地区)合作共赢提供决策支持。     

“一带一路”倡议下欧亚大陆陆海运输的空间均衡分析

在“一带一路”背景下,解析欧亚大陆陆海运输成本竞合基础上形成的空间均衡格局,是兼具理论与现实意义的重大经济地理问题。以北京和柏林为欧亚大陆两端终点,基于现有铁路路网,采用可达性分析方法,构建了陆海运输空间均衡分析模型,勾划出了欧亚大陆陆海运输平衡线,理清了“一带一路”背景下欧亚大陆的陆海运输空间竞合格局。研究发现,仅比较运费成本时,海运运输方式具有绝对优势,陆海运输平衡线沿俄罗斯近波罗的海区域—哈萨克斯坦—土库曼斯坦—塔吉克斯坦—中国西北部—蒙古—俄罗斯远东地区,将欧亚大陆划分为占比约1∶2的陆海运输空间竞合格局;考虑时间成本后,陆海运输空间竞合的平衡线向沿海地区明显推移,以德国柏林—黑海北岸—里海南岸—土耳其—青藏高原—中国宝鸡—大兴安岭—俄罗斯丘米坎为界,陆海运输基本形成了占比约1∶1的空间均衡态势。上述基于陆海运输成本角度的欧亚大陆陆海运输平衡线,与地缘政治学中陆权论和边缘地带论的相关结果在空间上高度吻合。基于此,本文进一步给出了欧亚大陆内陆区（陆运优势区）、海洋区（海运优势区）和陆海复合区的空间分区方案。由此,陆海运输空间均衡关系的综合分析可以成为探讨欧亚大陆地缘政治与经济空间格局的新视角,并为“一带一路”倡议的实施提供扎实的地理学科学基础。     

“一带一路”沿线地区关键生物多样性区域生态变化特征（英文）

KBA (Key Biodiversity Areas)是由IUCN提出并被国际社会认可的生态保护优先区域,评估其生态变化特征对生物多样性保护与自然保护地建设至关重要。“一带一路”沿线地区生态系统类型丰富,生物多样性保护价值极高,而沿线KBA更应该成为生态保护的核心目标。本文利用土地覆盖、归一化植被指数（NDVI）和夜间灯光数据（NTL）,从植被覆盖度和人类活动方面分别对沿线KBA的生态状况及其时空变化特征进行分析,得到以下结论：（1）KBA内的土地覆盖长期保持稳定,林地、荒野和草地是主要的土地覆盖类型;（2）KBA内NDVI总体上呈现增加的趋势,表明植被覆盖度在不断提高,少数植被退化的KBA主要分布在中南半岛、青藏高原以及西亚地区;（3）KBA内NTL总体上处于很低的水平,表明人类活动对自然生态系统的干扰程度十分有限,极少数分布于中东欧、印度、中南半岛以及地中海附近国家的KBA具有较强的人类活动且呈现出增加的趋势。本研究结果强调在KBA生态保护中充分利用生物群落演替规律,同时限制人类活动对自然生态系统的干扰,以推动沿线地区生物多样性保护与自然保护地建设。
