中文摘要	土地荒漠化是土地退化的一种主要形式,也是生态环境恶化的一种主要表现,严重制约着农业生产的发展.以1975年MSS卫星遥感影像、1990年TM卫星遥感影像以及2001年ETM卫星遥感影像等数据为信息源,采用地理信息系统的分析方法,引入荒漠化动态度等表征参量,建立了科学的荒漠化土地类型和土地动态转化分级系统,对我国松嫩平原近30年来的荒漠化土地进行了动态变化分析.结果表明,在1975～1990年期间,松嫩平原荒漠化土地呈明显发展趋势,其面积增加了1368931hm～2,荒漠化边缘地区恶化现象明显强于腹地;在1990～2001年期间,松嫩平原荒漠化土地总面积缓慢减少.减少面积为297867hm～2,荒漠化呈逆转趋势,逆转现象边缘地区强于腹地,土地荒漠化趋势基本得到遏制.
英文摘要	Land desertification is the main form of land degradation, and the main manifestation of ecological environment deterioration, which seriously restricting the development of agricultural production. Taking the MSS satellite remote sensing images which acquired in 1975, the TM images which acquired in 1990, as well as the ETM images which acquired in 2001 as the main data resources, using GIS analysis methods, the author introduced the descriptive parameters of desertification dynamic degree to established a scientific classification system about the land types of desertification and the land dynamic translations, then analyzed the dynamic changes of the desertification land in Songnen Plain over the past 30 years. The results show that: during the periods of 1975 to 1990, desertification land in Songnen Plain was obviously expanded, and its area increased by 1368931hm~2, the deterioration on the edge of the desertification was obviously stronger than the hinterland; in the period from 1990 to 2001, the total areas of land desertification in Songnen Plain was decreased slowly, the decrease area was 297867hm~2, and the desertification presented reversed trends, the reverse phenomena on the edge of the region was stronger than the hinterland, so the land desertification trends was basically kept within limits.
