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.
