遂宁组母质侵蚀规律的初步研究

A Preliminary Study on the Erosion Law of J_2s Parent Material

本文利用回归分析和通径分析等方法,研究了自然降雨条件下遂宁组母质侵蚀小区的径流量、入渗量、侵蚀量及其影响因子。结果表明:影响径流量的主要因子是降雨量;影响入渗量的主要因子是降雨历时;决定侵蚀量的主要因子是降雨能量。

Applying the methods of regression and path analysis and so on, the author stu-died the amount of runoff, infiltration, erosion and their influencing factors in ero-sion plot of J_2s parent material under rainfall. The results were shown as follows:the main influencing factors are the precipitation for the amount of runoff, theduration of rainfall for the amount of infiltration and the enegy of rainfall for theamount of erosion.
