摘要
在天然降雨条件下通过田间试验,研究降雨侵蚀力、植被及雨前土壤水分含量对土壤侵蚀影响的程度和植被、耕作措施对防治坡耕地土壤侵蚀的作用.作者认为川中丘陵区采用“拦截降雨、就地入渗”的耕作方法是防治坡耕地土壤侵蚀的关键措施.
On the nature rainfall condition, field experiments were conducted to study the effect of rainfall erosivity, vegetation and soil moisture before rainfall on the soil loss. And to study the function of the vegetation and cultivation methods for decreasing soil loss of slope land. It is considered tlat the key measures for controlling soil loss of slope land is 'Stopping runoff and diffusing at the spot' .
