摘要
该文在对湖北省通城县水土保持试验站，所布设的１２个野外试验观测小区，进行多年天然降雨观测的基础上，借助模拟降雨试验方法对红壤坡耕地不同耕作措施对水土流失的影响进行了试验研究。结果表明：１．横厢耕作措施是一种很好的水土保持措施，纵厢耕作措施比横厢耕作的水土流失量明显增力；２．在横厢耕作农地上实施轮作种植能改良土壤理化性质，保肥增产，但对水土流失并没有十分显著的影响；３．横厢耕作措施是一种在陡坡耕地上也能得到较好效益的水上保持措施。
Eased on the many year observation on 12 field experimental plots under physical rainfall in Tongcheng countystation of soil and water conservation,Hubei province, the influence of different tillage measures on soil and waterloss in red soil slope field has been approached using the way of simulated rainfall.It was shown that:1.leveltillage is a very good way for control soil and water Ioss;the amount of soil and water loss under vertical tillage ismore bigger than that under level tillage;the difference in the course of soil and water loss in slope field is notremarkable under normal rainfall or before rainstorm;2.corp rotation on level tillage field could improve physicaland chemical properties of soil,and could conserve soil fertility to increase yield; but its influence on soil and waterloss is not notable;3.level tillage measure is not only one of the measures for soil and water conservatioion. but alsothe one that can achieve more benefits on the steep slope field.
