摘要:
以东南沿海晋江西溪流域为例,初步研究了流域非点源污染与水系分维的关系.以Arc View GIS 3.2为研究平台,运用水系分维的计盒方法,计算了晋江西溪流域水系的宏观分维和划分为5个亚流域的微观分维,根据应用SWAT模型的模拟结果分析了西溪各亚流域非点源污染负荷与相应水系分维值的关系.研究结果表明,水系分维值越大,农田面积比例越大,流域土壤侵蚀程度越大,因此非点源污染负荷越大;此方法为流域非点源污染研究提供了新的途径.
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.
