摘要
伴随着坡面上产流、产沙过程，坡面形态亦在经历一个迅速变化的过程。本文利用随机理论和分形几何学方法，对坡地侵蚀实验资料进行分析，以坡面细沟密度指标及沟系分维数对坡地侵蚀的平面形态进行了定量描述。为研究坡地侵蚀程度提供了一种新的判定方法。
With the formation of surface flow and sediment slope pattern also changes greatly. The experimental data of the slope erosion are analyzed by stochastic theory and fractal geomety,and some quantitative descriptions for the slope pattern ofthe slope erosion are obtained according to the rill density and fractal dimension of the rills. This also provides a new methodto study the degree of the slope erosion.
