| 摘 要： | 自工业革命以来，全球环境发生深刻变化。生态脆弱区生态系统稳定性差、抗干扰和自我恢复能力弱，在全球变化背景下，自然资源供给能力下降、土地退化、生物多样性减少、灾害频发，生态系统面临巨大风险，亟需开展生态脆弱区全球变化风险应对研究。本文重点对中国典型生态脆弱区全球变化风险来源、全球变化对生态脆弱区的影响、全球变化风险应对等研究进行总结，并提出未来全球变化应对策略，以期促进中国典型生态脆弱区生态系统对全球变化响应的深入理解，提高生态脆弱区应对全球变化的能力。生态脆弱区全球变化风险源于环境变化对自然、社会、经济复杂系统的影响。全球变化对生态脆弱区的影响是显著的，以气候变化为主要标志，人类活动为主要驱动力，引起极端气候事件、灾害频发、土地退化、植被生产力降低、生物多样性减少、冰川冻土消融和水资源格局改变等环境问题，并在未来全球变化持续影响下可能加剧，而生态建设工程的实施显著改善了生态环境。今后应加强自然、社会、经济系统耦合，加强资源环境要素监测和全球变化风险评估与预警等方面的研究。

| Abstract: | The global environment has undergone profound changes since the industrial revolution. Due to the poor stability， anti-interference and self-recovery abilities of ecosystems， global change has led to the decline of natural resource supply capacity， land degradation， biodiversity reduction， frequent disasters， and increased ecosystem risks in ecologically vulnerable regions. Therefore， it is urgent to implement researches on global change risk in ecologically vulnerable regions. This study mainly summarized the researches on the risk sources and the impact of global change on ecologically vulnerable areas of China， as well as the response to global change. The study then put forward the future strategies for global change to promote the in-depth understanding of the response of ecosystem to global change and improve the ability to cope with global change in typically and ecologically vulnerable regions of China. The risk of global change in ecologically vulnerable regions comes from the impact of environmental change on complex systems of natural， social， and economic. Global change has a great impact on the ecosystem of ecologically vulnerable regions， with climate change as the main symbol and human activities as the main driving force. Global change causes extreme climate events， frequent disasters， land degradation， the reduction of vegetation productivity and biodiversity， the melting of glaciers and frozen soil， and the change of water resources pattern， which may intensify under the continuous impact of global change in the future. However， the implementation of ecological construction project has significantly improved the ecological environment. In the future， we should strengthen the researches on the coupling of natural， social， and economic systems， the monitoring of resources and environmental factors， and the risk assessment and early warning of global change. |
