| 摘 要： | 通过对内蒙古宁城、和林、东胜三个试验站进行坡面径流泥沙试验,采用数据分析法,研究内蒙古黄土丘陵区坡耕地在一次降雨中各典型影响因子与土壤侵蚀量之间是否存在相关关系及相关程度问题。研究表明该区次降雨雨强、降雨前期土壤含水量、植被覆盖度、坡面坡度和土壤侵蚀量之间存在着密切的相关关系。

| Abstract: | Through the dome runoff sediment deposition trial in three experiment stations including Ningcheng,Helin,Dongsheng in Inner Mongolia,using the way of data analyzing,whether the relationship of representative influencing factor of soil erosion and the amount of soil erosion of sloping farm land in loess hilly in Inner Mongolia during once rainfall is exist and how much is the degree of correlation.The results showed:there were close relationships of rainfall intensity during once precipitation,soil moisture content between two adjacent rainfall,plant coverage,grade of slope and the amount of soil erosion. |

| Keywords: | loess hilly area rainfall intensity during once precipitation grade of slope plant coverage soil moisture content between two adjacent rainfall soil erosion |
