跨界保护区网络构建研究进展

跨界保护区网络是生物多样性保护网络的一种特殊形式,对保护国家或地区边界线附近丰富的生物多样性具有重要意义。构建跨界保护区网络已被列为《生物多样性公约》(Convention on Biological Diversity)框架下"保护区工作组"的一项战略任务,涉及生态、环境、经济、政治等多个领域,成为全球保护区研究领域的热点问题之一。然而,目前我国对跨界保护区的研究尚处于起步阶段,在如何构建不同尺度的跨界保护区网络等方面的研究仍有待进一步加强。在分析了全球、洲际、两个或多个国家和地区之间等不同尺度跨界保护区网络研究的基础上,综述了国内外基于"节点"-"廊道"模式的跨界保护区网络构建研究进展,并结合我国跨界保护区网络建设的实际情况,对我国未来跨界保护区网络构建研究进行了展望。

A review oftransboundary protected areas network establishment

Current rate of biodiversity loss has been far greater than the natural rates from fossil record. The most common conservation strategy is the establishment of protected areas network. As a special form of biodiversity conservation networks, the transboundary protected areas (TBPAs) network is designed to protect key ecosystems and high biodiversity areas among different countries or regions. The establishment of TBPAs network had been listed as one of the major goals of the Convention on Biological Diversity, which concerned both ecological/environmental issues and social/political issues. The TBPAs network may span international, interprovincial, or regional boundaries, which is normally composed of transboundary nodes and corridors. However, the establishment mode of TBPAs network in different scales (e.g., the global scale, the continental scale, and among different countries or regions scale) is still poorly reviewed. And studies on TBPAs network in China is still in its initial stage. In this paper, wereview related studies on TBPAs network in different scales, and methodological studies on the TBPAs network establishment based on the "node - corridor" mode. In general, the node of one TBPAs network should be areas with high conservation value, high species richness, more endangered species, or key biodiversity resources. And the development of transboundary corridor can connect different transboundary nodes into a TBPAs network, which can facilitate the flow of gene, energy, and substance. We also discuss the TBPAs network status across China, such as the TBPAs among China, Russia, and Mongolia in the northeast, the TBPAs among China, Russia, Kazakhstan, and Mongolia in the northwest, and the TBPAs among China, Laos, Myanmar, Thailand, Cambodia, and Vietnam in the southwest. Finally, we recommend potential studies on TBPAs network in China: 1) enhancing the TBPAs network studies in larger scales; 2) proposing TBPAs network method and management model suitable to China; 3) evaluating the effectiveness of TBPAs network; 4) studying new issues related to the TBPAs network; and 5) developing integrated policy and institution of the TBPAs.
