| 摘 要： | 利用小型径流观测场对比观测了不同林地降雨、径流过程以及全年的土壤侵蚀量。结果表明 ,与裸地相比刺槐林有很好的水土保持作用 ,能明显地减少地表径流和泥沙侵蚀。3 0 mm左右降雨量 ,有林地减少地表径流的能力是无林地的 3倍以上。2 0 0 0年径流观测场有林地土壤流失量为 179.4 2 g/ m2 ,无林地土壤流失量为 980 .1g/m2 。无林地土壤侵蚀量随降雨量的不同约是有林地的 3～ 5倍 ,有林地年度总侵蚀量较无林地减少 5倍以上。

| Abstract: | The rainfall-runoff process and soil erosion quanti ty were researched by runoff experimental field in 2000. As a result silver chai n forest land has a better capacity in soil and water conservation than naked l and. It can reduce surface runoff than naked land when rainfall changes around 3 0mm. In 2000, 179.42 g/m~2 soil were lossed in silver chain forest land, 980.1 g/m~2 in naked land on the contrary. Along with the change of rainfall, soil erosion quantity in forest land is about 3~5 times than in naked land. Total soi l erosion quantity in forest land can be reduced 5 times compared with naked lan d. |
