摘要

坡耕地由于人为耕作管理作用

造成地表高低起伏

影响着坡面地表径流和产沙。在室内人工降雨试验基础上

分析了坡面耕作措施的蓄水保土效益。等高耕作蓄水效益为70.56%～10.07%

平均值为51.58%

保土效益为76.60%～21.66%

平均值37.73%。同时分析了坡度和雨强对坡面耕作措施蓄水保土效益的影响

以期服务于坡耕地治理。

Abstract

Cultivation of slope farmland influences surface runoff and sediment movement on slopes. This paper analyses the benefits to soil and water conservation of tillage measures

with reference to rainfall influences. The results show that: the benefit to water conservation of contour tillage is 70.56%~10.07%

with an average of 51.58%; the benefit to soil conservation of contour tillage is 76.60%~21.66%

with an average of 37.73%. In addition

the influence of tillage measures under different slope and rainfall intensity conditions is analyzed in order to demonstrate potential improvements on all slope farmland.
