【摘要】 针对干旱和水土流失并重的小浪底库区坡地,本文以该区5种主要坡地利用类型(传统耕作农田、撂荒地、间作地、林地、果园)为研究对象,探讨了不同坡地利用方式对坡地土壤化学性质的影响。结果表明:改变土地利用方式后土壤化学性状得以改善,总的梯度变化依次为:传统耕作地<果园地<撂荒地<林地<间作地。更多还原

【Abstract】 Soil and water loss and drought are serious in the Xiaolangdi reservoir area.This paper focuses on five different slope land use patterns(conventional tillage cropland,orchard land,fallow land,intercropping land and woodland) in this area to study the effect of different slope land use patterns on the chemical properties of soil.The results have shown that the chemical properties of soil are improved and the sequence of change is as follows:the conventional tillage land<orchard<land fallow land<woodland<intercropping land.更多还原
