| 摘 要： | 论述的内容分两部分，一是野外人工模拟降雨的试验方法，对侧喷式降雨装置的安装参数，主要的降雨特性以及试验小区的布设与设备进行了介绍。二是对林地与开垦裸露地的降雨试验结果分析，认为，林地具有截流、拦蓄的功效，可以改善降雨径流入渗条件。在不同处理的情况下，林地与新开垦地、撂荒地相比，其效益，可减少径流90%以上，可减少泥沙99%以上。

| Abstract: | Firstly,the experiment methods of simulated rainfall is introduced in this paper,in-stalling’ parameters of rainfall simulator of side sprinkler,and properties of simulated rainfall and installation of test plots in the field are discussed.Secondly.experimental results of forest land, and reclaimed and bare land have been analysed.It is considered that forest land has function of interception rainfall and increased infiltration.Comparing forest land with new cutivated land or wasteand,benefit cf reduced runoff and sediment in forest land is above 90% and 99% respec-tively,at the different experiment treatment conditions. |

| Keywords: | forest land simulated rainfall experiment forest land being reclaimed runoff and sediment |
