摘要

通过对典型黄土丘陵沟壑区纸坊沟流域土壤养分分布规律的研究，结果表明：土地利用状况，植被因素及人工熟化过程对黄绵土土壤肥力的影响，水土流失起了关键性作用。不仅如此，还对本地区主要土类的成土过程起了不可替代的作用，在地带性黑垆土上发育的幼年性黄绵土，其剖面养分分布特征与黑护土截然不同，它在完整的坡面上养分分布具有特殊性，即坡上部土壤养分含量低于坡下部。

Abstract

the distribution of soil ferility in Zhifang gully watershed is studied

The result shows①soil and water loss plays an important role in the impacting of land use

vegetation andartificial soil improvement on loess soil fertility;②soil and water loss also plays an important roleon the formation of main soil types;③the fertility distribution in the profile of loess soil

whichgrows on Heilu soil

is completely different from Heilu soil;④the fertility distribution in thewhole slope land of loess soil has the different propertys

namely

the fertility on upper slope ismore than that on down-slope
