流域水生态功能区划是水生态和水资源综合保护的重要前提和基础。在综合调查分析辽河流域辽北地区典型流域自然环境特征、水文数据和地理信息数据的基础上，结合辽河流域水生态功能一级、二级分区结果，建立水生态功能三级分区指标体系，对辽宁省辽河流域清河、凡河流域进行水生态功能三级分区。结果表明：清河流域可分为7个水生态功能三级区，凡河流域可分为4个水生态功能三级区；水生态服务功能类型共划分为5类：生物多样性与生物栖息地维持功能、产品提供与农业生产功能、水源涵养与水文调蓄功能、人居保障与城市发展功能和水土保持与生态修复功能。水生态功能三级分区结果为辽河流域实施水生态综合管理提供了科技支撑，同时也为中国水生态功能分区技术规范的制定提供了科学依据。

Aquatic ecological regionalization of watershed is an important foundation for integrated management of water ecology and water resource protection.According to investigation results of natural environment,hydrological data and GIS data in the typical Liaohe river watershed of northern Liaoning province,division indexes of the third level were determined by results of the first and second levels,and the third ecological regionalization was obtained in Qinghe and Fanhe river basins.The results indicate that it can be divided into seven and four aquatic ecological regionalizations of the third level in Qinghe and in Fanhe river basins.Ecological service function can be divided into five categories,namely,maintaince of biodiversity and habitat safety,product supply and agricultural produc-tion,water conservation and regulation,human settlements protection and urban development,soil conservation and ecological restoration.The results of third level aquatic ecological regionalization could provide scientific references for comprehensive prevention of water pollution and the integrated management of aquatic ecological regionaliza-tion.
