Water resources are becoming more and more shortage in Tarim arid region. So it is important to control the expansion of land reclamation and enhance the efficency of water resources utilization in upper reaches of Tarim River. It is also significant for the development of Tarim region to resolve the conflict between agricultural using water and ecological using water. Remote sensing technology is the best way to analyze the dynamics of land use. In this paper, the author discussed the dynamics of land use in typical region-Alaer(K-44-127,1∶100,000) by using the aeronautical maps and satellitic maps which were made in 1959,1983,1992 and 1996. The results showed that in this region the artificial oasis and residential area were enlarged step by step. On the contrary, the area of natural vegetation shrank year by year. As for the other land using types, the area of lakes decreased quickly and the area of usless land types has no great change for these years, e.g. the desert and the salina. Therefor the local goverment should strictly control the enlargement of land reclamation in upriver of Tarim River in order to save the lower reaches of Tarim River. And at the same time, we should strengthen the construction of vegetation to improve the ecological environment.
