Abstract:: Arid areas of Tarim River region is the most significant in the process of desertification in the world. Since the past 50 years the irrational development activities, resulting in severe degradation of ecological environment. Especially as the main natural vegetation and ecological processes of ecosystems due to spatial and temporal patterns of water resources adversely affected by anthropogenic change, resulting in environmental degradation, the decline of natural vegetation, desertification intensified. This study, mainly start from the desertification causes of the lower reaches of Tarim River, starting from the relations of the whole and part to find desertification reasons in the lower reaches of the Tarim Basin, the use of 3S technology and relevant statistical analysis Tarim River Regional population growth, water use on the impact of desertification means as well as the extent of the impact. Analysis results show that the lower reaches of Tarim River in Xinjiang direct causes of desertification is the increase in water consumption in the main stream and downstream to the reduction of water,the water reduction from the upper and middle reaches of the basin is closely related to the increase in arable land. Analysis show that population growth and arable land have great relevance.Further found that in this typical inland of the Tarim river basin,the population growth is not only closely related the cultivated land area (in the arid zone basin equivalent to the basic irrigation area),but different population growth above the valley of the arable land has also increased the different drive effect, the drivers power of population growth effect on the land degradation of downstream have the transitivity from the origins to downstream,the land desertification of the downstream,mainly produce to transit through the impact that the population growth of the origin and the upper and middle reaches effects on the water of the lower reaches.
