摘要：

基于流域水生态功能分区的水生态安全评价是指导流域水生态“分类、分区”综合管理的前提，本文在流域中小尺度上依据水生态空间格局分异的自然特征和社会属性，以辽河流域的清河和凡河支流为对象，在流域水生态功能三级分区的基础上，运用“压力—状态—响应模型”（PSR），通过对流域社会经济压力指标、环境压力指标、城市发展指标、资源环境发展指标、投资指标、治理指标等因素分析，筛选出13个评价指标。利用生态安全综合指数法，将流域水生态安全划分为极不安全、不安全、基本安全、安全、非常安全五个级别。其中，清河流域Ⅳ-5-9、Ⅳ-5-10、Ⅳ-5-11、Ⅳ-5-12、Ⅳ-5-14区处于基本安全，Ⅳ-5-8、Ⅳ-5-13属于不安全；凡河流域4个水生态功能三级区中，Ⅳ-5-1、Ⅳ-5-2、Ⅳ-5-3区属于基本安全、Ⅳ-5-4区为较安全。基于水生态功能分区的水生态安全评价和级别划分可为辽河流域水生态保护与流域生态管理提供科学依据。

Abstract:

An aquatic ecoregion-based assessment for water ecological security can offer a premise for the integrated management guidance of watershed ecological with the rule of “by type, by region”. Based on the natural features and social attributes of the spatial differentiation of ecological security pattern in basins on small and medium scales, the typical two tributaries in the northern Liaoning were selected as the study areas, i.e. the Qinghe river and the Fanhe river. On the basis of the third grade  aquatic ecoregion, 6 elements including socio-economic pressure, environmental pressure, urban development indicators, development of resources and environment indicators, investment indicators, governance indicators were anlayzed and 13 indexes were selected according to the pressure-state-response model (PSR). The ecological security is divided into five degrees according to ecological security index by using the comprehensive ecological security index method, and they were specially insecurity, insecurity, basically security, security, special security.At the Qingheriver basin, ecoregion with codes of Ⅳ-5-9,Ⅳ-5-10,Ⅳ-5-11,Ⅳ-5-12,Ⅳ-5-14 are basically security and those with codes of Ⅳ-5-8 and Ⅳ-5-13 belong to insecurity. The ecoregions with codes of Ⅳ-5-1,Ⅳ-5-2,Ⅳ-5-3 of Fanhe river basin belong to basically security, and that with code of Ⅳ-5-4 is security. The results of aquatic ecoregion-based ecological security and grade division offer scientific references for water ecological protection and overall ecological management of Liaohe river basin.
