中文摘要	以处于季风边缘区的太仆寺旗2000年与2005年的TM4、3、2波段合成的标准假彩色影像数据为主要数据源.并对TM遥感影像进行合成、增强、纠正、镶嵌和人机交互判读,生成两期的荒漠化动态变化图.在GIS软件支持下,建立了两期的荒漠化现状数据库,采用转移矩阵法和数学模型法,建立2000-2005年沙质荒漠化土地转移矩阵和运算动态度,分析北方环境敏感区荒漠化变化.分析得出:轻度荒漠化土地面积增加51121.6hm~2;中度和重度荒漠化土地面积分别减少-68948.8hm~2和一5978.7 hm~2.其中,1/3的中度荒漠化土地逆转成非荒漠化和轻度荒漠化土地.重度风蚀荒漠化转变成轻度风蚀荒漠化的面积2168.9hm~2.而非荒漠化土地变成了轻度风蚀荒漠化土地达21393.9hm~2.但是非荒漠化土地面积增加35374.5hm~2.而且重度和中度荒漠化土地演变成轻重度风蚀荒漠化土地也很多.因此,总体而言,太仆寺旗荒漠化恶化趋势得到了有效的遏制,自然环境明显改善.这归功于大力实施荒漠化防治措施的结果.但是也存在非荒漠化地区的生态保护力度不够或不合理的土地利用方式导致了局部地区的荒漠化迅速发展的现象.
英文摘要	Take the standard fake colorized image data that composed by TM4 ,3 , 2 band on September 1,2005 and July 1,2000 as main data source, current desertification pictures of Taipusi Baaner and the change of deser-tification development picture between 2000 and 2005 were generated. In support of GIS software, we built the data base of desertification current situation and development in 10 years, at the same time , set up transfer ma-trix and dynamic rate of sandy deaertification lands through count change of area in various degrees sandy desorti-fication lands by adopting transfer matrix method and mathematical modeling method , set up transfer matrix and mathematical trends of sandy desertification between 2000 and 2005 in order to analyze the change of desertifica-tion in north sensitizing environment. The conclusions were as follows: the area of mid-degree sandy desertifi-cation became small, one thirds of them turned into non-sandy desertification and low-degree sandy desertifi-cation; the areas of low-degree sandy desertification obviously increased, the areas of mid-degree and strong sandy desertification turned into low-degree sandy desertification is as two thirds as the increased areas, the other is that non-sandy desertification turned into low-degree sandy desertification; the increase of non-sandy desertification gives first place to low-degree sandy desertification and strong sandy desertification.Through analyzing, the development of desertification in Taipusi Banner is limited as a whole, the part of place is still worsening. This is the result of Taipusi Banner after taking desertification prevention after 2000. But the pro-tection degree of some non-sandy desertifieation place is insufficient or the unreasonable land utilization has led to prompt development of desertifieation in some areas.
