研究了长江三峡花岗岩出露区林地土壤流失特性，结果表明由鳞片状面蚀导致的土壤流失量分布与月降雨量的分布趋势基本一致，二者呈现出较为明显的线性相关关系，植被盖度≥0．70的林地土壤流失多集中发生在6～9月份，土壤流失量在500t／（km2·a）以下，盖度＜0.7的林地土壤流失年内分布时间多在3～10月份，土壤流失量为500～6000t／（km2·a）．
The results showed that the distribution of soil loss caused by scale-like surface erosion and the distribution of monthly rainfall are basically in line with each other, showing a significant linear correlation between vegetation cover The soil loss ≥0.70 forestland concentrated in June to September, the soil loss is less than 500t / (km2 · a), the coverage of forest land with the coverage of less than 0.7 is mostly distributed in the period from March to October, the soil loss The amount of 500 ~ 6000t / (km2 · a).
