Micro-relief characteristics of loess sloping farmland under different tillage practices and its effects of soil and water conservation
|
Abstract:
The spatial distribution of micro-topographical features of loess sloping farmland and its effects of soil and water conservation were studied using GIS under simulated rainfall conditions.The results showed that the descending order of the changes of micro-relief is contour tillage,artifical dig,artifical hoe,and CK,and the mean changes of different type of tillages(CK,artifical hoe,artifical dig and contour tillage) decreased as 0.015,0.014,0.018 and 0.015m after simulated rainfall conditions,respectively...
