摘要
流域生态系统健康评价是流域生态环境规划和管理的依据,是协调流域社会经济发展与生态环境保护、促进流域可持续发展的重要措施。通过运用文献资料法、综合归纳分析法等方法,阐述了生态系统健康与相关概念的关系,以流域研究单元为例,系统总结并对比分析了生态系统健康评价的内容、方法、指标体系和评价标准,提出了流域生态系统健康评价流程,指出目前研究存在的问题,并做出展望,在深入探究相关概念基础上,利用3S空间技术建立统一完善的生态系统健康评价指标体系和分级标准,建立动态长期生态系统健康监测数据库。
Watershed ecosystem health assessment,the basis of watershed ecological environment planning and management,is playing an important role in coordinating watershed social economic development and ecological environment protection,and promoting sustainable development of the watershed.Using literature material and comprehensive analysis method,this paper expounded the relationship between ecosystem health and related concepts,summarized systematically and analyzed the contrast of ecosystem health assessment in the aspect of contents,methods,index system and evaluation standards by taking watershed as a research unit,proposed the workflow of ecosystem health assessment,pointed out the existing problems and the prospect of it：using the 3S spatial technology to perfect the unified index system and evaluation standards and creating a long-term dynamic ecosystem health monitoring database on the basis of exploring the related concepts.
