塔里木河流域生态系统健康评价指标体系的构建

流域生态系统健康评价研究是目前生态学研究的一个新概念、新问题,旨在探讨在人类强烈活动干扰下遭忖受严重污染与退化的流域生态系统的健康问题,生态系统健康是人类与环境间的相互协调关系及实现生态可持续发展的重要基础.依据野外调查资料、遥感影像和社会经济数据,分析表明：水资源是决定塔里木河流域生态系统健康与否的关键因素,人类对水资源的不合理开发利用是导致本流域生态环境恶化的根本原因.因此从水资源、生物多样性、生态系统的弹性和经济社会几方面的健康出发,选取相应的一系列指标,构建了塔里木河流域生态系统健康评价指标体系,并确立了各指标健康程度的度量标准.从而为本流域的生态环境管理提供可参考的理论基础.

SET-UP OF INDEX SYSTEM TO WATERSHED ECOSYSTEM HEALTH ASSESSMENT IN THE TARIM RIVER

The study of Watershed Ecosystem Health is a new idea and a new issue by now. The aim is to study the health problem of Watershed Ecosystem which has been badly pollution and degraded under the strongly disturbance of Human activity. Ecosystem Health is a important bases to realize mutual coordinate between human and environment and to realize sustainable development of the Ecology. According to investigated data in field, photograph of remote sense and economic-social data. Analized shows Water Resources is the most important factor for Watershed Ecosystem Health. It results in the Ecology,s degrade that human,s unreasonable develop and usage of Water Resources . So from Water Health, Biodiversity, Ecosystem Instate and Health to setup the compre- hensive index system of the Watershed ecosystem health assessment. The aim of Watershed Ecosystem Health Assessment is recover and manage Watershed Ecosystem and to realize sustainable development of the Watershed.
