摘要

通过黄土坡面模型和人工模拟降雨试验

定量分析了在45

87和127 mm/h降雨强度下坡面细沟形态量化参数特征。结果表明

细沟形态量化参数随雨强的增加并不是单一的增加或减少

而是随着侵蚀的发展呈波动变化。裸地1和裸地2由于土壤容重的不同表现出不同的变化趋势。细沟分形维数与长度、密度间存在良好的正相关关系

说明非线性量化参数与传统单因子量化参数之间不是孤立的。分形维数作为整体性的量化参数

在坡面侵蚀发育的一定阶段内能够较好地表征细沟长度、密度的变化趋势。

Abstract

Using the loess hillslope model and the artificial simulated rainfall experiment

morphological development of rill and the quantitative characteristics of morphological parameters were analyzed quantitatively under the rainfall intensities of 45

and 127mm/h. The results showed that the quantitative morphological parameters of rill was not a single increase or decrease with the rainfall intensity increase

it presented the volatility changes with soil erosion development. Bare ground 1 and bare ground 2 showed different trends of change because of their different soil volume weight. A good relationship between the rill length and density and the fractal dimension of rill showed that the non-linear quantization parameter was not independent with the traditional one-factor quantization parameters. The fractal dimension as a quantitative parameter

can better reflect the change of rill length and density.
