摘    要:为探究土壤侵蚀各影响因子在一个较大的地理系统内的组合变化关系,以淮河流域为研究区,通过收集流域内土壤、植被、地形、气候等数据,利用二元相关分析、偏相关分析和通径分析方法,对流域尺度的土壤侵蚀各影响因子进行了分析。结果表明:在流域尺度上,对土壤侵蚀起主导作用的因子是地形起伏度,其次是坡耕地面积比和植被覆盖度。地形起伏度和坡耕地面积比及植被覆盖度之间具有较好的相关性,地形起伏度除直接对土壤侵蚀产生影响外,还通过影响坡耕地的分布和植被覆盖度而对土壤侵蚀产生综合影响。

关 键 词:土壤侵蚀  影响因子  二元相关分析  偏相关分析  通径分析  淮河流域

Abstract:In order to find out the combinative effect of all the possible influencing factors on soil erosion in an larger geographical system,the paper analyzes each influencing factor of soil erosion on the basin scale by taking the Huaihe River basin as a study area and using the methods of bivariate correlation,partial correlation and path analysis and through collecting the data of soil,vegetation,topography and climate of the basin.The outcomes show that on the basin scale,the relief topographic is the main factor for controlling soil erosion and then is the ratio of slop farmland and vegetation coverage.There is a fairly good relativity among the relief topographic,ratio of slop farmland and vegetation coverage.Except direct effect to soil erosion,the relief topographic also has integrated influence to soil erosion through the slope farmland distribution and vegetation coverage of being influenced.
Keywords:soil erosion  influencing factor  partial correlation analysis  path analysis  the Huaihe River basin
