摘要:
干旱区绿洲人类和自然环境的和谐相处直接影响着绿洲经济稳定持续的发展。选用研究区四期遥感影像，结合分类后比较的方法，分析区域土地利用/覆盖变化轨迹模型以及在研究时段内，土地利用/覆盖类型之间的转化过程和流向，并将土地利用/覆盖的变化按照驱动因素分为未变化类，自然因素导致的变化类和由人为因素导致的变化类三种形式，分别做统计分析，定量化分析自然和人为因素对区域环境的影响程度。结果表明，在近15 a间，研究区土地利用/覆盖面积变化较为显著，其中耕地和盐渍地的面积变化最为明显，分别由5.596%、7.570%增长到17.063%和17.228%。根据变化轨迹可得，自然因素所引起的变化主要是草地和未利用地之间的转化，占区域总面积的22.5%；人为因素所引起的变化主要是耕地的开垦以及水库渠系的修筑，占区域总面积的22%。随着绿洲人口经济的发展，人类活动对土地利用/覆盖的影响越来越频繁，直接影响着区域土地利用/覆盖格局的变化。
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.
