Simulation of Organic Matter Loss in Area around Taihu Lake
The agriculture around Taihu Lake is highly developed, but a large amount of sand and organic matter is directly brought into Taihu Lake from farmland in rainy season and is seriously polluting the water quality of the lake. In order to make a quantitative analysis for the influence of organic matter to the water body of Taihu Lake, the area around Taihu Lake is divided into two land area of paddy farm and dry land to set up a mathematical model of organic matter loss from farmland. Runoff generation, water drainage, soil erosion and organic matter loss are stimulated in different typical periods of high-flow, normal-flow and low-flow by the model. The modeling result shows the soil erosion and organic matter loss increase in an exponential form with the increase of surface runoff intensity. The sand and organic matter in the surface runoff are pollutants in themselves and also carrier of other toxic substances, which are seriously influencing the water quality of Taihu Lake. Effective measures attached with importance must be taken in the water quality program and treatment for the Lake.
