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。
Through the runoff and sedimentation tests on three experimental stations in Ningcheng, Helin and Dongsheng of Inner Mongolia, the data analysis method was used to study whether the correlation between the typical factors and soil erosion in sloping fields in a loess hilly region of Inner Mongolia was There are related issues and related issues. The results show that there is a close correlation between rainfall intensity, soil moisture content before rainfall, vegetation coverage, slope gradient and soil erosion.
