摘　　要：辽河流域为重化工业发达、寒冷地区缺水的流域,其水生态完整性恢复具有典型性和代表性。从水资源开发利用结构、污染物排放量与水环境容量及水生生物多样性变化等方面分析了辽宁省辽河流域水生态完整性存在的问题;梳理、总结了国家水体污染控制与治理科技重大专项“十一五”“十二五”期间在辽宁省辽河流域的技术研发成果,阐述了其针对物理完整性的水生态基流保障实践,针对化学完整性的重污染行业全过程污染削减实践,针对生物完整性的水生态恢复实践;并从大江大河流域特性、水生态完整性修复的必要性与重要内容,治理中如何统筹水资源、水环境、水生态,贯穿物理完整性、化学完整性、生物完整性修复的理念等方面提出建议,以期为我国开展大江大河流域水污染防治提供经验和借鉴。The restoration of water ecological integrity in Liaohe River Basin is typical and representative for the basins with developed heavy chemical industry and water shortage in cold regions.The problems of water ecological integrity in Liaohe River Basin of Liaoning Province were analyzed from the aspects of water resources development and utilization structure,pollutant discharge,water environment capacity and changes of aquatic biodiversity.The technological research and development achievements of National Major Science and Technology Program for Water Pollution Control and Treatment(referred to as the“Water Program”)in Liaohe River Basin of Liaoning Province during the 11th and 12th Five-Year Plan periods were summarized.On this basis,the practice of water ecological base flow guarantee for physical integrity,the practice of pollution reduction for chemical integrity in the whole process of heavy pollution industry,and the practice of water ecological restoration for biological integrity were expounded.Some suggestions were put forward from the aspects of the characteristics of large river basins,the necessity and important content of water ecological integrity restoration,the way to coordinate water resources,water environment and water ecology in the treatment,and the way to carry through the three integrity restoration thoughts of physics,chemistry and biology,so as to provide experience and reference for the prevention and control of water pollution in large river basins.
