Study on the relation between Ecological water level and Ecological environment Variation in Baiyangdian Wetland
Baiyangdian is the largest wetland in north China, it plays an important role in many aspects such as climate regulation, biodiversity protection, flood control, and local fishery production etc. The hydrological data of water resources quantity have been analyzed for Baiyangdian wetland and established the relationship between Water resources quantity and Ecological Water Level. Define the conception of Ecological Drought of Baiyangdian Wetland .Demonstrate that ecological drought water level which decide the Ecological environment will be degradation is the key date to determine whether supplementing water to Baiyangdian Wetland. And the ecological destructive water level have been analyzed. Through analyzing the monthly water level change regulation, ecological drought water level as the key date has been calculated, which make a contribution to the forecast of ecological drought development.
ecological drought water resources degradation the distinguish date of ecological drought water diversion
