| 摘 要： | 通过赣北典型的第四纪红壤坡地16个小区资料的分析,得出土壤侵蚀量(A)与降雨量(P)、降雨强度(I)以及两者乘积存在着显著的相关性,拟合曲线的最优回归方程均为幂函数方程。其中降雨量、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,幂函数方程:A=b0(PI)b1可以很好地揭示降雨因子与土壤侵蚀之间的内在规律。

| Abstract: | There was a significant correlation between soil erosion(A) and rainfall(P),rainfall intensity(I),the arithmetic product of P and I through analyzing the data of 16 plots in the slope land of quaternary red earth in the north Jiangxi province,and power function equation was the most splendid regression equation in all fit curves.Meanwhile,the correlation between arithmetic product of rainfall and rainfall intensity and soil erosion was more significant.So power function equation: A=b0(PI)b1 could be used to well explain the intrinsic orderliness between the factors of rainfall and soil erosion in the slope land of quaternary red earth. |
