应用江西省10个县(市)典型沙土流失42个小区的试验观测资料,分析了红壤丘陵水力侵蚀区降雨与土壤侵蚀的关系.结果表明:土壤侵蚀量与降雨量、降雨强度以及两者乘积存在着显著的相关性,且降雨量、降雨强度两者的乘积与土壤侵蚀量之间的相关性更为显著;在第四纪红壤坡地和花岗岩发育红壤坡地,分别采用幂函数方程和二次曲线方程揭示降雨因子与土壤侵蚀之间的内在规律.
Based on the experimental observation data of 42 districts of typical sand loss in 10 counties and cities of Jiangxi Province, the relationship between rainfall and soil erosion in red soil hilly region was analyzed.The results showed that the relationship between soil erosion and rainfall, rainfall intensity and the product of the two The correlation between the product of rainfall and rainfall intensity and the amount of soil erosion is more significant. On the red soil slope of the Quaternary and the red soil slope of the granite, the power function equation and the second The curve equation reveals the inherent law between rainfall factor and soil erosion.
