| 摘 要： | 运用2000-2011年MODIS NDVI数据监测了新疆地区的沙漠化变化,分析了该区沙漠化对气候变化的响应,并对典型区域沙漠化的主要原因进行了调查和研究。研究结果显示,近10 a来,新疆地区沙漠化整体趋缓,但局部地区沙漠化状况继续加剧;沙漠化对年降水量的变化响应明显,特别是在北疆地区响应十分显著;新疆沙漠化加剧最严重的区域位于南疆盆地的河流中下游;沙漠化类型退化的生态系统主要为草甸生态系统,引起沙漠化的主要原因是水资源利用空间的改变,特别是地下水水位的变化。

| Abstract: | Using the MODIS NDVI data from 2000 to 2011 in Xinjiang region, the desertification variation was monitored, and the response of desertification to climate change was analyzed, then the reason of desertification was surveyed. The results indicated that the desertification was controlled in Xinjiang region in the recent ten years, but in some areas it was continually worsen. The response of desertification to annual precipitation was dramatically, especially in the northern of Xinjiang region. The most serious area of desertification in Xinjiang region was located in the middle and lower reaches of rivers in the Tarim Basin. The degenerated ecosystem mainly was the meadow ecosystem, and the cause of desertification was mainly the spatial change of the water resources utilization, especially the change of groundwater water level. |
