中文摘要	本文运用GIS、RS手段,以航天遥感MSS、TM、ETM为主要信息源,对松辽平原进行多时相、大面积沙质荒漠化遥感动态监测,从中探索松辽平原沙质荒漠化动态变化的规律,为经济发展和生态建设提供科学依据。研究结果表明:近30年来松辽平原沙质荒漠化面积变化呈现快速增加和缓慢减少两个阶段,即70年代中期到80年代末,松辽平原沙质荒漠化总面积呈快速增加趋势,动态度为-3.91%;而80年代末到本世纪初则呈缓慢减少趋势,动态度为0.82%。松辽平原沙质荒漠化的重心随之呈有规律的移动,沙质荒漠化面积增加时重心向东北方向移动,速率为3.08km/年。沙质荒漠化面积减少时重心向西南方向移动,速率为1.64km/年。
英文摘要	Based on GIS and RS technology,the multi-temporal and large-area dynamic remote sensing monitoring of sandy desertification in Songliao Plain were carried out using MSS,TM and ETM data as the chief information source,and the dynamic change rule of sandy desertification was found which could be used to provide scientific basis for the construction of economy and ecology.The results showed that the area change of sandy desertification during the past 30 years in Songliao Plain could be divided into two periods: rapid increasing and slow reducing.From the middle of 1970s to the late of 1980s,sandy desertification area showed rapid increasing tend,and dynamic velocity was-3.91%;However from the late of 1980s to the early of this century,it presented a slow reducing trend and dynamic velocity was 0.82%.The centre of the sandy desertification in Songliao Plain showed a regular move with the change of two periods.When the area of the sandy desertification was increase,the centre moved to the north-east direction and the velocity was 3.08 km per year;When the area was reducing,the centre moved to the south-west direction and the velocity was 1.64 km per year.
