Abstract:Basement fractures are closely related with environment geochemistry landscape and distribution features of soil erosion in the Ordos Basin.The basement fractures control environment geochemistry landscape and the features of element distribution, and especially the Dingbian-Suide and Huach-i Datong fracture zones divide the Ordos Basin into two completely different landscape sect ions of geochemistry and physiognomy.To a certain extent,the basement fractures control topography,landform, physiognomy,neotectonic movement, rock type,lithologyst ructure,soil type and property,and shallow groundwater and its characters,and indirectly control long-term alteration of rock and soil,and dynamic conditions of wind and w ater.Study of the relationships between basement fractures and soil erosion has great significance for guiding comprerensive control of soil erosion.
