摘　　要：应用RS与GIS技术,利用2004年和2009年TM遥感数据,对克拉玛依市境内的荒漠化土地现状与动态变化进行监测研究,并对其时空特征进行分析。结果表明:克拉玛依市荒漠化土地面积2009年为727472.85hm2,占总面积的94.73%。其中,风蚀荒漠化面积431803.62hm2,占监测区总面积的56.23%。2004年荒漠化总面积为732893.96hm2。近5a来,克拉玛依市荒漠化土地面积总体呈略微减少趋势,但荒漠化程度明显变轻,主要表现为极重度风蚀荒漠化和盐渍化荒漠化分别减少了21.96%和7.44%。Karamay city is one of the regions with the most serious land desertification in China. In this paper,the actuality and dynamic change of land desertification in Karamay city are monitored and lucubrated using RS and GIS technology,TM data in 2004 and 2009,and the dynamic change of land desertification in Karamay city is analyzed. The results show that the area of desertification lands in Karamay city in 2009 was 727472.85 hm2 and occupied 94.73% of the total land area in the city,in which the area of wind erosion desertification lands was 431803.62 hm2 and occupied 56.23% of the total desertification lands area. The area of desertification lands in 2004 was 732893.96 hm2. Since recent 5 years,the change of total area of desertification lands in Karamay city had a little decrease,but the desertification degree has significantly become better,and the areas of extremely severe wind erosion desertification lands and salinization desertification lands have been reduced by 21.96% and 7.44% respectively.
