中文摘要	利用RS与GIS技术对新疆境内的荒漠化土地进行监测分析，以新疆全境为控制总体，采取卫星数据解译结合现地调查及抽样方法狭取全疆荒漠化现状。临测调查表明：新疆是个荒漠化分布极广的地区，荒漠化面积占监测区面积的77．08％。存荒漠化土地类型中，荒漠化耕地占1．92％，荒漠化林地占4％，荒漠化草地占45％，荒漠化未利用地占49％。在荒漠化程度中，非荒漠化土地占22．92％，轻度荒漠化占5．69％，中度荒漠化占16．58％，重度荒漠化占33．19％，极重度荒漠化占21．6l％。按荒漠化主导因素：风蚀荒漠化占58．23％，水蚀荒漠化占8．69％，盐渍荒漠化占6．52％，冻融荒漠化占3．64％。
英文摘要	The land desertification in Xinjiang was monitored and analysed on the basis of RS and GIS. The method for drawing samples was used for obtaining the desertification condition throughout Xinjiang and interpreting satellite data in combination with ground investigations. The PCI software has been used to deal with remote sensing data such as image enhancement, classification, auto-classification and so on. Meanwhile the interpretation symbols about desertification type and land type were identified based on ground investigations. According to interpretation symbol, the computer processing and disposition have been used to explain investigation factors. The result was imported with the form of VFP database table, and the attributive database was established. By integrating attributive database, the geographic information data were obtained by using ARC/INFO software, statistical and calculated data have been summarized for the present situation of desertification of Xinjiang. According to the monitoring result, Xinjiang is a widely desertified region, in which desertified area occupies 77.08% of the whole monitored area. For the desertified land type: the desertified farmland is 1.92%; desertified woodland is 4%; desertified grassland is 45%; and unused land is 49%. For the desertification degree: non-desertification is 22.92% ; weak desertification is 5.69% ; moderate desertification is 16.58%; serious desertification is 33.19%; and extremely serious desertification is 21.61% . Based on the main factors of desertification, wind-erosion desertification is 58.23%; water-erosion desertification is 8.69%; saltation-desertification is 6.52%; and freezing-thawing desertification is 3.64%.
