晋西北地区是我国黄土高原及北方农牧交错带的重要组成部分．土地荒漠化动力因素主要包括水动力和内动力．风、水动力具有随季节周期性交替和空间上相互交错渗透的特点，风、水两种动力有时互为条件，有时相互制约，它们共同决定了晋西北全区侵蚀过程的垂向分带和地貌形态．
Northwestern Shanxi is an important part of the ecotone between agriculture and animal husbandry in the Loess Plateau and the North China. The driving forces of desertification include hydrodynamics and internal motivation. Wind and hydrodynamics have the characteristics of cyclical alternation and spatially interpenetrating infiltration with each other. Wind and water dynamics sometimes mutually condition each other and sometimes restrict each other, and they jointly determine the vertical zonation of the erosion process in the whole area of northwestern Shanxi and Geomorphology.
