摘要

降雨是造成我国东南部土壤侵蚀的主导因子

风化花岗岩又是南方土壤侵蚀的重要组成部分。本文通过在风化花岗岩侵蚀区的塘背小流域。选择了两个自然坡面径流小区

对观测的降雨量、降雨强度和土壤侵蚀量等三个因子进行了系统的分析

找出了月土壤侵蚀量在一年内呈双峰曲线的分布规律

建立了降雨量、降雨强度和土壤侵蚀量三因子幂函数的预测预报方程

为同类地区的水利、水土保持工程设计

农田基本建设以及治理和利用花岗岩侵蚀土壤提供了科学依据。

Abstract

Weathered granite areas are the important part of soil erosion in southeast China. In the corrupted area of weathered granite

two plots of natural slope were chosen in Tangbei small watershed. Having observed the rain capacity

rainfall intensity and the amount of soil erosion

we analyzed the three factors systematically

found the distributed law showing a curve with a double peak about the soil erosion every month in a year

and then set up a soil loss predict equation. It will present the scientific basis for the project of water conservancy

soil and water conservation and. agricultural capital construction with improvement and utilization of granite erosion in the same regions.
