生态系统健康评价——概念构架与指标选择

Assessment of ecosystem health - concept framework and indicator selection.

在探讨生态系统健康概念构架的基础上 ,寻求对管理景观中的生态系统健康进行整体性评价的合适指标 .健康的生态系统不仅在生态学意义上是健康的 ,并能维持健康的人类群体及有利于社会经济的发展 .健康生态系统的一般特征是恢复力、多样性和生产力 .建立生态系统健康评价指标的第一步是指标选择原则的确定 ,根据生态系统健康评价的目的和指标筛选的原则 ,把生态系统健康指标体系 (EcosystemHealthIndicator ,EHI)分为生物物理指标、生态学指标和社会经济指标 .

Based on the concept framework of ecosystem health,this paper discussed the suitable indicators to synthetically assess the ecosystem health in governed landscape.Healthy ecosystem means not only ecological health itself,but also the long-term maintenance of healthy human population and the beneficial promotion of social and economic development.Resilience,biodiversity and productivity are the characteristics of healthy ecosystem.The first step in the structure of indicators to assess ecosystem health should be the determination of precise indicator principles.According to the purpose of assessment and the principles of selecting indicator,the indicator system for assessing ecosystem health can be divided into three categories,namely,biophysical indicators,ecological indicators,and social and economic indicators.
