摘　　要：PSR模型是有效的生态评价和管理模型,近年来其在生态系统评价领域的运用越来越普遍。本文对PSR模型的产生、原理及其主要的类型进行介绍,介绍其在生态评价领域的运用概况,并重点介绍其在流域-河口及海洋生态安全评价中的运用,为河口生态安全评价做准备。本文对PSR模型在河口生态安全评价中的适用性进行分析,并基于PSR模型构建了河口生态安全评价指标体系,最后指出该模型在评价中存在的主要问题。PSR model is an efficient model for evaluating and managing ecosystem and has been used more and more popular in the field of ecosystem assessment in recent years. This paper introduced the origin ,theories and types of PSR model ,as well as its application in the field of ecosystem assessment, especially the assessment of base-estuary and ocean ecosystem safety, searched for assessing the estuary ecosystem safety. Practicability of PSR model in the assessment of estuary ecosystem safety was analyzed. It constructed the index system of estuary ecosystem safety assessment and put forward some problems about this model eventually.
