摘要

研究表明，黄土高原土壤崩解速率存在明显的地域分异规律，且呈现出自西北向东南次第减慢的趋势。根据主要参数，将研究区内土壤崩解速率划分为极慢、很慢、一般、很快和极快5个区。影响土壤崩解速率的主要因素有：农业耕作、植（生）物生长和土壤成土过程三个方面。还发现，土壤崩解速率与土壤抗冲性之间存在密切的幂函数关系。

Abstract

The results show that soil disintegration rate on the loess plateau is faster in the north-western region than in the southeastern region It takes regional change law clearly。Based on theexperiment data

we classfy the soil disintegration rate of this area as 5 regions.That is the slowestregion

very slow region

slow region

fast region and very fast region. The important factor that ef-fect the soil disintegration rate are agriculture tillage

plant or biotic growth and soil-forming pro-cess.Besides.the relationship between soil disintegration rate with soil anti-scourbility is powerfunction.
