Selection of Priority Areas for Hydrological Ecosystem Conservation in Hai Basin, China
Global climate change results in the reduction of precipitation. At the same time, the socio-economic rapid development led to water shortage. In Hai Basin, the pressure on water resource and hydrological ecosystem caused by above factors led to serious degradation in many ways-wetlands dry up and serious pollution, groundwater funnel deepened, soil erosion, as well as habitat degradation. Eighty-five hydrologic units were analyzed as basic evaluation unit in four aspects: river restoration, biodiversity conservation, groundwater recovery and soil and water conservation. A matrix-based approach is developed to characterize the priority areas based on the seriousness of ecosystem degradation and the protection of importance on classification. According to this approach, the mountains area of Yongding River, the plains of the North Four River, Cangzhou coastal areas, Tianjin, as well as Tuhai& Majia River in Hai River were selected as ecological restoration priority regions. This method can be used for the integrated river basin planning because of its simpleness and smartness.
