Study on Calculation of Ecological Water Demand for Reservoir Wetland

It is related to the sustainable utilization of water resources to solve the question of the wetland degradation,to protect the ecological environment of wetland,and to establish a harmonious society between mankind and the water resources.A minimum water level of ecological method was adopted to determine the minimum water depth and the smallest surface area,to analyze the changes of wetland area and land utilization,and to study the ecological environment of wetland and the biological diversity of Tuanbowa.By comparing the precipitation in different hydrological year,the minimum water requirements of different ecological environments were calculated.
