摘要
“生态系统完整性”概念正在逐步成为公共环境政策和决策的基础,许多区域生态系统管理的规划和政策都将生态系统完整性作为目标和原则。本文建立了长江源区多尺度生态系统框架,依照生态系统完整性的定义,发展了长江源区生态系统完整性评价的指标体系,对源区进行了生态系统完整性的测量和评价。根据完整性的评价结果,将长江源区划分为生态良好区、生态脆弱区和优先生态恢复区。
The concept of ecosystem integrity was proposed to protect the biological and ecological resources against the interference of human activities, and has being turned into a basis of public policy and decision making in environmental issues. Many of the ecosystem management and planning activities are taking ecosystem integrity as the principle and goal. In this paper, a hierarchical ecosystem framework of the headwaters of Yangtze River was established, and an indices system for the assessment of the ecosystem integrity of the headwaters was developed. According to the assessment results of ecosystem integrity, the headwaters of Yangtze River could be divided into three units, i. e. , ecologically good, ecologically vulnerable, and to be ecologically restored with priority.
