| 摘 要： | 水系分形维数的计算与分析,有助于深入理解其与地貌发育、流域径流和侵蚀产沙等过程之间的关系。本文从分形维数的计算原理出发,结合目前最流行的GIS软件,提出了新的水系盒维数计算方法,并以安塞纸坊沟流域为例,说明该方法能较好地反映流域地貌特征。

| Abstract: | Calculation and analysis dimensionality of drainage fractals is helpful for understanding relationship among geomorphic development,runoff of river and sediment yield development.The paper starts with the principles of the dimensions,combining with the most popular software of GIS,puts forward a new method to calculate the drainage dimensional.For an example of Zhifanggou of Ansai,it explains the method that can better reflect some features of the valley landscape. |
