摘要
对马莲河流域各水文站的日径流过程形态分维进行了对比分析。结果显示,同一流域干流的日径流过程分维值要明显大于支流的分维值,下游大于上游,4个水文站分维值年际变化趋势基本保持一致。从日径流过程分维与土壤侵蚀的拟合研究发现,日径流过程分维值与土壤侵蚀存在密切的相关性。
Fractal dimensions of the daily stream flow of Malian drainage were calculated according to the Fractal Theory. The results showed that the fractal dimensions of the main stream and down stream gauging staitions were higher those that of the tributary,headwater gauging stations. From the corrrlative and regression analysis of stream flow fractal dimension and soil erosion,it was found that the two had distinct relativity,which could bring forward a new method for the study of watershed water and soil loss,soil erosion and so on.
