摘要: 青藏高原对我国乃至亚洲生态安全具有重要的屏障作用。在全球变化和人类活动的综合影响下,青藏高原呈现出生态系统稳定性降低、资源环境压力增大等问题,突出表现为:冰川退缩显著、土地退化形势严峻、水土流失加剧、生物多样性威胁加大与珍稀生物资源减少、自然灾害增多等。这些问题严重影响了青藏高原区域生态安全屏障功能的发挥。针对当前高原生态安全状况,在总结相关研究成果和生态建设实践经验的基础上,提出了加强青藏高原国家生态安全屏障保护与建设的对策建议:加强气候变化对青藏高原生态屏障作用影响及区域生态安全调控作用的基础研究;系统开展高原生态安全屏障保护和建设关键技术研究与示范推广;部署建设生态屏障功能动态监测体系,加强生态安全屏障保护与建设成效评估,构建评估体系和标准,并凝练经验,以系统提升国家生态安全屏障的总体功能,在应对全球变化中占据主动地位。

Abstract: The shelter function of Tibetan Plateau has an important effect on the ecological security in China, even in Asia. Under the joint influence of global change and human activities, ecosystem destabilizing and resources and environment pressure increasing emerge on the Tibetan Plateau, which have caused some problems, including significant glacier retreat, serious land degradation, aggravated soil erosion and water loss, increased threats to biodiversity along with decreased rare and specious biological resources, and natural disasters increasing. These problems have a great influence on regional ecological security shelter function on the plateau. Based on the relevant research and practical experience in ecological construction, some suggestions are proposed to strengthen ecological protection and construction of the national ecological security shelter zone on the Tibetan Plateau at present, namely, strengthening basic research on the Tibetan Plateau ecological shelter impacts and regional ecological security enhancement and climate change mitigation; developing the key technology of protection and construction of the national ecological security shelter zone on the plateau and demonstration; striving to set up a monitoring system of ecological shelter function, intensifying evaluation of protection and construction efficiency of ecological security shelter zone, perfecting evaluation systems and standards, and summarizing experience, so as to enhance the overall function of national ecological security shelter and to further take the initiative in dealing with global change.
