祖厉河流域水系分维与地貌发育阶段浅析
Fractal Dimension of the River Networks and Developing Stage of Drainage Geomorphic of Zuli River Basin
【摘要】 根据Horton-strahle水道序列划分原则,采用数学模型,对黄河上游水土流失严重的祖厉河流域进行分析计算,得出该流域水系分维及其主河道分维,并确定了其流域发育阶段,为同类型区的小流域水系分维计算、地貌发育阶段的确定和水土保持工作提供可操作性强的方法。
【Abstract】 Zuli River basin where the area was corroded intensively was studied by applying the calulating method.It emphatically calculated the fractal dimension of the river networks on the drainage geomorphic system.And then,discussed the developing stage of drainage geomorphic.It supplys a operable method to calculate the fractal dimension of the river networks and determines developing stage of drainage geomorphic for other similar areas.
