| Abstract: | Based on the landforms, function and cover feature of the ground in East Lake district, and distribution resularity of run-off from rain and nonpoint pollution of the lake at time and in space the mathematical model for calculatinS run-off discharge, soil loss and nutrient loss of the lake valley is established. Several model parameters for different ground surface at each run-off area are determined by site test. Computer programmes on ron-off ratio, soil loss, total nitrogen load and total phosphorus load are worked out. A scientific basis for harnessing nonpoint source pollution of the East Lake is provided, which can be a reference of other similar engineerings. |
