摘要:

长江及其流域生态环境保护是长江经济带建设的基础和重要的支撑保障。长江横贯中国东中西三大地带,水量丰沛、水生态系统服务价值巨大。长江经济带生态区位重要,生态系统类型多样,生物多样性丰富,自然与人为因素影响下的生态环境变化呈现明显的区域差异。本文在系统分析长江经济带生态环境现状特征的基础上,总结了长江经济带面临的灾害威胁大、环境污染重和生态退化快等主要生态环境问题与威胁,提出了建设长江经济带绿色生态保障工程体系,加快形成开发集约集中、生态自然开敞的国土空间开发格局,加大生态系统完整性和连通性建设与保护力度,强化节能减排和流域环境综合治理,以及率先建立和完善生态文明制度体系等生态环境保护总体策略,确保长江经济带成为“水清地绿天蓝”的绿色生态走廊。

Abstract:

Eco-environment protection of the Yangtze River and its river basin is the important foundation and support for the construction of the Yangtze River Economic Belt (YREB). Crossing the western, central, and eastern regions of China, the Yangtze River has abundant water resources and significant ecosystem service functions. Moreover, the YREB has an important location ecologically, with diverse ecosystem types and rich biodiversity; strongly affected by human activities and natural factors, the main trend of ecological environment change, which are dominated by ecological degradation and declining environmental quality, shows significant regional differences. Based on the analysis of the basic characteristics of the environment of the Yangtze River Economic Belt, this study identified the major environmental problems and threats it faces. First, natural disasters are of diverse types and widely distributed in the YREB and have caused heavy losses. Second, water and air pollutions are still serious. Third, the ecosystems are fragile and sensitive and ecological degradation is rapidly progressing. This study proposes a series of ecological environment protection strategies, including the construction of the green ecological protection project of the Yangtze River Economic Belt; accelerating the formation of a land development pattern dominated by intensive, concentrated spatial development and natural and open ecological space; strengthening the development and protection of ecosystem integrity and connectivity; strengthening energy conservation and comprehensive watershed environmental management; as well as setting up and improving the system on ecological civilization construction.

Key words: green ecological corridors, regional ecological security, ecological civilization, Yangtze River Economic Belt (YREB)
