摘要
依托长江黄金水道,建设长江经济带是新时期国家重大区域发展战略。长江经济带是形成国家“一体两翼”开发开放大格局的主干轴线。文章在系统分析长江经济带的长江生态系统服务价值、生态区位、生态类型、生态地理格局、自然条件、自然生态灾害等生态本底基础上,总结了长江经济带面临的水环境和大气环境污染严重、长江干支流和湖泊水生态显著退化、重大工程生态环境累积影响不断显现、江河湖泊关系不和谐等重大生态环境问题;建议将长江水生态环境保护摆在头等重要的位置,率先实行水质目标管理,形成开发节约集约与生态自然开敞的国土空间开发保护格局,持续实施长江经济带绿色生态保障工程,以及打破部门和地方分割,实施流域综合管理等生态环境保护总体策略,以确保长江经济带“共抓大保护、不搞大开发”战略实施。
The Yangtze River Economic Belt is a major regional development strategy of China,to form the backbone axis of the national“one body and two wings”development and opening-up pattern.This paper systematically analyzed ecological background and status of the Yangtze River Economic Belt,such as ecosystem service value of Yangtze River,ecological location,ecological types,ecological geographic pattern,natural conditions and natural ecological disasters.Then the major ecological and environmental issues were summarized,including serious water and air pollution,dramatic degradation of main tributaries of the Yangtze River and lakes,the increasing cumulative ecological and environmental impacts of major projects,and the unharmonious relationship between rivers and lakes.Finally,four protection strategies were proposed to ensure successful implementation of the well-coordinated environmental conservation and avoiding excessive development in the Yangtze River Economic Belt,including:implementing water quality goals management by stressing water eco-environmental protection of the Yangtze River with the top priority;forming a land and space development pattern dominated by intensive,concentrated spatial development and natural and open ecological space;continuing to implement the green ecological protection project of the Yangtze River Economic Belt;and breaking the division of departments and localities,and implementing comprehensive watershed management.
