摘    要:鄂尔多斯盆地的环境地球化学景观与水土流失分布特征与基底断裂关系密切。盆地基底断裂控制了盆地的环境地球化学景观和元素分布特征,尤其是定边—绥德断裂带和华池—大同断裂带将盆地分成两个截然不同的地球化学、地貌景观区;鄂尔多斯盆地内的基底断裂在某种程度上控制了盆地的地势、地形、地貌、新构造运动、岩石类型、岩性构造、土壤类型及其性质、浅层地下水及其性质,并间接地控制了土壤岩石后期的改造、风与水的动力条件等因素。研究盆地基底断裂与水土流失的关系,用于指导水土流失综合治理具有重要的现实意义。

关 键 词:鄂尔多斯盆地  基底断裂  环境地球化学  水土流失

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 Huachi-Datong fracture zones divide the Ordos Basin into two completely different landscape sections of geochemistry and physiognomy.To a certain extent,the basement fractures control topography,landform,physiognomy,neotectonic movement,rock type,lithology structure,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 water.Study of the relationships between basement fractures and soil erosion has great significance for guiding comprerensive control of soil erosion.
Keywords:Ordos Basin  basement fractures  environment geochemistry  soil erosion
