| 摘 要： | 选择元谋干热河谷地区典型区段，采用坡面径流小区观测方法，以自然荒草丛坡面为对照，研究在自然降雨条件下，反坡梯田整地、水平阶整地两种造林整地方式对坡面径流泥沙的截流减沙作用。结果表明，反坡梯田和水平阶造林整地对地表径流的拦蓄都具有很好的作用，但反坡梯田整地方式比水平阶拦蓄径流能力更强，观测期反坡梯田整地和水平阶整地比自然坡面产流量分别减少71．42％和33．68％，产沙量分别减少56．02％和38．57％；实施造林整地措施后，随着时间的推移，产流产沙量越来越少，单场暴雨或特大暴雨对拦蓄径流和拦截泥沙效果起主导作用。

| Abstract: | Taking natural uncultivated grass slope as the control,the effect on runoff interception and sediment reduction by adverse slope terrace and level bench site preparation methods for afforestation was comparatively studied under the natural rainfall condition in the hot dry valley of Yuanmou County by means of runoff plot observation method.The results showed that both types of adverse slope terrace and level bench site preparation played a very good role in the runoff interception,whereas the adverse slope ... |
