摘要

以晋西黄土区吉县蔡家川流域为研究对象

通过利用MATLAB软件的系统聚类分析方法

对蔡家川嵌套流域中主沟道及6个小流域进行流域地形地貌属性相似性分析和分类的基础上

分析研究了在地形地貌特征相似流域类型中不同土地利用及森林覆盖率对流域径流过程的影响。分析结果表明

在流域地形地貌特征相似的条件下

森林植被具有减小流域雨季径流总量的作用

流域径流量及径流过程不仅受该流域的森林覆盖率影响

而且整地措施良好的人工林地调节径流、减少雨季洪水径流总量的效果更加明显。

Abstract

Based on the quantitative analyzing of the similar topographical characteristics and classification of Caijiahuan watershed and its 6 branches by system clustering analyze of MATLAB in the Loess Plateau

the western Shanxi province

impacts of the forest coverage and land-use types on runoff in small watersheds that are similar topographical characteristics were researched in this paper. From the result of analyze

forests have the function of decreasing amount of rain season runoff. Amount and process of runoff in watershed were impacted by forest coverage. By favorable measure of soil preparing

artificial forests have evident function on adjusting runoff and decreasing amount of peak flow of rain season.
