With the development of our society,irrational land use/cover change has become one of the important factors in water environment deterioration in Yangtze River Basin.Soil erosion is one of the most serious eco-environment problems in Yangtze River Basin in China.Silt,nutritive element of soil,residual pesticide,fertilizer,bodies of animal and plant are constantly transferred into water bodies with soil erosion.As a result,the amount of SS,COD,TP and TN increased continually and the water quality is continually declined.During the flood season,the pollution of water quality in mainstream of Yangtze River is mainly caused by non-point source.There are many studies related to the area of Yangtze River basin,but little research which is focused on the NPS pollution caused by land use/cover change.Based on the actuality of non-point source pollution in the Yangtze River Basin and the development of 3S techniques,constructing an information system to simulate the relationship of land use/cover change and non-point source pollution in Yangtze River Basin is reported in this paper.At the end of this paper,the framework and functions of the simulation information system are sketched out.With the support of the system,some benefits will be brought to the Yangtze River Basin.
