Desertification in western China is quite serious. Multi-disciplinary approach, from the macro, meso and micro aspects of the study in the western region the evolution of desertification and its spatial and temporal characteristics. The results show that: the western land desertification in the long history of years of evolving, and showing a gradually increasing trend; the factors leading to desertification, including both natural and social, nearly five thousand years of human factors often influence than natural factors. Poor production of human life will greatly speed up land desertification process, and scientific and rational land development environmental protection measures are able to play to curb desertification, slow and reverse the effect. The desertification of the western regions in China is quite serious. This paper examines the evolution and the characteristics of time and space of the desertification of the western regions in China from the marco-, medium-and micro-iew point by means of multidisciplinary intersection . The findings show that the desertification of the western regions has been formed gradually in the past historical stages and the situation has gradually worsened. The factors of the desertification includes such two aspects of nature and society, whereas the influence of human powers usually surpasses that of natural factors. The human beings, inedequate mode of production and living will accelerate the process of the desertification, while the scientific land development and rational environmental protection will play an important role of depression, retaining and reversion towards the desertification
