Study On The Ecological Restoration Measures Of Suzi Valley By Dahuofang Reservoir Water Conservation District

In traditional water conservancy projects, people excessive use of concrete. Masonry and other hard to reach the river training materials to meet the flood control, drainage, irrigation, navigation requirements. In contrast, ecological restoration governance Basin Reservoir Water Conservation District is a comprehensive systems engineering, which relates to water conservation, ecology, environment, landscape and the cultural aspects, taking into account the ecological, economic and social benefits.Dahuofang Reservoir is one of the nine key cities nationwide water supply sources, reservoirs and water conservation in the region has a large number of river resources, due August 16,2013 torrential rain caused flooding and destruction of human life and production, resulting in the current Reservoir water quality decline, watershed ecological destruction. In order to improve the water quality and watershed Reservoir environment, this paper is creation for the ecological restoration measures and evaluation of Suzi Basin conservation area.1. Using field survey and data analysis methods of the natural basin profiles,, status quo and the "8.16" flood disaster situation Survey and analyze the main problems exist.We can determine the objectives and measures for ecological restoration of the river basin management on this basis.Binding of the Hydrological analysis determine the boundary line.2. Reservoir ecological restoration and protection of water quality as a guide for the ecological restoration of watershed management design. It is including ecological riparian zone management measures, ecological wetland management measures, outfall into the river governance governance, floating storage intercepted governance four parts.3. Validation of ecological restoration measures in order to further analysis, using the analytic hierarchy process (AHP) to governance measures to evaluate the effect after implementation. From five aspects, such as water quality, water function set out to build a suitable evaluation index system of river ecological restoration; To each index weight determined by expert judgment method and its quantitative, then evaluate the river after the ecological restoration effect. The results showed that the ecological restoration of land have achieved good results.By design studies, with a view to better solve the ecological restoration of watersheds water quality protection, interception pollution, people and water issues, Through the ecological evaluation can find existing problems in the ecological system, provide idea; and methods can learn from everyone room for other basin reservoir water conservatior district ecological management, research and development of integrated watershec management play a catalytic role, through shared governance-related river conservatior area, to achieve improvements Reservoir water quality and ecological environment.
