摘要
采用人工模拟降雨装置,对毛竹林地土壤流失进行了试验,结果表明:林地坡度是影响林地土壤流失的主要因子,坡度在30以上时,极易造成林地土壤冲刷;地表覆盖能有效地降低地表径流中的泥沙含量;大雨、陡坡、全垦造成的水土流失非常严重。
Experiment on soil erosion at bamboo stand with stimulated raining showed that slope was the major factor of soil erosion, especially when slope was over 30. Coverage on soil could effectively decrease soil content on surface runoff. Heavy rainfall, steep land and broadcast preparation of soil would cause serious water and soil erosion.
