| 摘 要： | 从指标体系构建、评价单元与数据来源、健康状况的评判三个方面对我国基于PSR框架模型流域生态系统健康评价研究进行综述,并根据PSR框架模型的评价思路与流域生态系统特征,对基于PSR框架模型流域生态系统健康评价的研究进行展望。最后提出因地制宜是PSR框架模型流域生态系统健康评价方法的生命力所在;应突出水环境状况变化核心内容,依＂人—地—水＂脉络确定健康评价指标体系;评价指标的观测应重视时间尺度上的纵向变化;＂3S＂是流域生态系统健康评价的必要技术手段。

| Abstract: | This paper first summarized the advances achieved in assessing watershed eco-system health based on PSR model from the perspective of index system,evaluation units and data sources,and health status diagnosis.And,according to the PSR framework model and watershed ecosystem characteristics,it put forward the prospect on the research of watershed eco-system health assessment： Focusing on local conditions is the most important factor in evaluating watershed eco-system health based on PSR model;the index system should be established based on water environment and ＂people-land-water＂ clue;more attention should be paid to the observation of longitudinal changes in time scales;and ＂3S＂ is the necessary technical means. |
