国家“十一五”期间，辽河流域水污染治理取得了突破性进展，实现了流域干流水质化学需氧量（COD）消灭劣V类的目标。为了巩固辽河干流治理成果，实现可持续发展的长远目标，辽宁省划定了辽河保护区，成立了保护区管理局，这是国内成立的第一个以流域综合管理为目标的行政机构，并进行了辽河保护区治理与保护研究。本研究以建设防洪安全、水质良好、生态健康、景观优美的健康河流生态系统为出发点，融合了水利学、生态学、环境学、景观学、经济学等多学科交叉理念，统筹考虑水利工程、污染治理工程、生态修复工程、示范区建设工程等项目的相互影响及关系，分别进行了土地利用、生态系统修复、河道综合治理、生态示范区建设、治理与保护能力建设5个方面的研究。

In the National "11th Five-year" period,the Liaohe River basin water pollution control acquired breakthrough progress. It eliminated water quality worse than class V for chemical oxygen demand (COD) in the mainstream of the whole river basin. In order to consolidate the control achievements of the Liaohe River mainstream,and to achieve long-term goal of sustainable development,Liaoning Provincial Government desi-gnated the mainstream of Liaohe as conservation area and established a conservation bureau. This is the first administration to be set up in China carrying out integrated basin management. So we do the research about the Liaohe River control and conservation. The goal of the research was to restore a healthy river ecosystem including flood control,good water quality,healthy ecology and beautiful landscape. It's realize the integration of hydraulics,ecology,environmentology,landscape esthetics,economics and other interdisciplinary concept in ecological environment protection plan of China. It's also considerate the interaction and relationships of hydraulic project,pollution control project,ecological restoration project and demonstration area construction project. We have completed five special researches of land use,ecosystem restoration,integrated river management,ecological demonstration area construction,and control and protection capacity establishment.
