- Abstract:
-
By taking Xixi watershed of the southeast coastal area as an example,the relationship between the non-point source pollution and the river fractal dimension is preliminarily studied.Using ArcView GIS 3.2,the fractal dimension of Xixi watershed and its five subbasins have been calculated with the box-counting method.According to the SWAT model simulation results,the relationship between the non-point source pollution and the river fractal dimension of the five subbasins is analyzed.The results show that,the higher the watershed fractal dimension is,the higher the farmland area ratio is,and more serious the soil erosion is,so more serious the non-point source pollution is.The fractal analysis can bring forward a new method for the study of non-point source pollution.
