流域生态系统调查技术指标体系研究

Research of the technical index system for Watershed ecosystem survey

流域生态健康研究是目前生态系统研究领域的研究热点之一,其主要通过对流域生态系统中不同生态指标的调查及评价指数来反映流域生态系统的健康状况。因此,在总结欧美发达国家流域生态系统调查技术指标体系的基础上,结合中国目前流域调查技术现状以及流域水环境管理需求,构建流域生态系统调查技术指标体系,为流域生态系统健康状况调查评估、识别主要生态环境问题提供可参考的技术方法。

Watershed Ecosystem Health Research is one of research hotspots in the field of ecosystem health research. Surving of status and trends of surface waters quality is an important method to assure healthy of desired characteristics of watershed ecosystem. A new surving index system is required based on ecological methodologies,which accurately represents status and trends in quality of watershed ecosystem. Therefore, it＇ s based on the development law of watershed ecosystem and its interaction with human activities,Analyzed the main problem in the investigation and technology of watershed ecosystem.Recognition of human activities on the scope and degree of the influence of watershed ecosystem, Research all kinds of technical indicators,construction of index system of Watershed ecosystem survey technology,for the watershed ecosystem survey assessment,to identify the main ecological environment problems to provide technical method for reference.
