地貌条件与土壤侵蚀关系的定量研究——以窟野河流域为例

Qnantitative study of the relationships between topographical conditions and soil erosion

在实地考察的基础上,运用数理统计相关分析法,对窟野河流域地貌条件与土壤侵蚀的关系进行定量分析.结果表明,窟野河流域相对高度和平均坡度与土壤侵蚀模数的关系分别为线形和幂函数正相关;平均坡长与土壤侵蚀面为幂函数负相关.

Based on the extensive investigation and statistics,then the relationships between topographical conditions and soil erosion in Kuye River basin are quantitatively studied.The analytical resurts show that soil erosion modulus increase with the increase of ralative heights of topography and average slope of hillside;the surface of the soil erosion decreases with the increase of the length of hillside.
