Abstract—Due to the change of natural conditions, the water environmental capacity presenting time dynamic characteristics. In this study, the Xuchang section of Qingyi River Basin was taken as the research object, The EFDC model was adopted, COD and ammonia nitrogen as the main pollution factor, the dynamic water environmental capacity was studied. By constructing a one-dimensional hydrodynamic water quality model of Qinghe River Basin, Calculate of Water Environmental Capacity of Main Tributaries in Qingyi River Basin. The result shows that the environmental capacity of main stream is occupying the most proportion in the whole river basin, Qingni River is much more than others in the main stream. In order to control the water quality of Qingyi River Basin and control the total amount of pollutants in Qingyi River Basin, we established the water quality and water quality model in Qingyi River Basin.

Index Terms—Qingyi river, EFDC, dynamic environmental capacity.
