Abstract:: The article selected the typical oasis of Weigan and Kuqa rivers as the study area, utilizing the the past 15 years of remote sensing images combing with the comparison of the post-classification methods, established a regional land-use change trajectory model, and analyzed the transformation process of the type of landuse changes during the study periods. At the same time, to analyze temporal human impact on the environment, according to the driving factors, we have classified all found trajectories into three generic classes, namely, unchanged, human-induced change and natural changes. Then, using the statistical analysis methods, quantitatively analyze the impact degree of the natural and man-made factors to the regional environment. The results showed that in the study period, the change of land use/land cover is remarkable, the most notable of the types are farmland and salinization soil, their area respectively rised from 5.596%, 7.570% to 17.063%, 17.228%.According to the trajectory analysis, the change aroused by natural factors are mainly grassland and non-utilizingland, and the change area occupies 22.5%. The human-induced changes are dominated by cropland and reservoir, whose total area occupies 22.0%. With the population and economic development, the impact of human activities on land use/cover increased frequently. In this paper, the spatial-temporal trajectory pattern of land cover change contributed to a better understanding of human factors on the arid region of the fragile ecological environment.
