利用2009年和2011年分辨率为10 m 的法国 SPOT 卫星和日本 ALOS 卫星遥感资料，以 ArcGIS 9.3软件 ArcMap模块为平台，采用人机交互目视解译对辽河保护区地类特征进行提取，并监测分析保护区生态恢复状况。结果表明：2009年保护区土地利用类型以旱田、芦苇型湿地和水域为主，三种土地类型所占比例为72.9％；2011年土地利用类型主要以水域、芦苇型湿地和草地为主，三种土地利用类型所占比例为62.9％。2011年保护区土地利用变化主要表现为旱田大幅度转出，转化为水域、草地和林地，与2009年相比，耕地显著减少，植被覆盖度增加了15.4％。

Using remote sensing data from the France SPOT and Japan ALOS satellites with 10 meter-resolution in 2009 and 2011,the land use type characteristics in the Liaohe river protection zone were extracted using visual in-terpretation in the ArcMap module platform of ArcGIS 9.3,and the status of ecological recovery in the Liaohe riv-er zone was analyzed.The results show that the land use types in the protection zone in 2009 are dominated by up-land,reed wetland and water area,and their total proportion to the whole protection zone is up to 72.9%,while the land use types in 2011 are mainly dominated by waters,reed wetland and grassland,and their total proportion to the whole protection zone is 62.9%.The land use change characteristics from 2009 to 2011 in the protection zone show that most of cultivated areas in 2009 are converted to waters,reed wetland and grassland areas in 2011.Com-pared with 2009,the cultivated areas decrease significantly and the vegetation coverage area increases 15.4% in 2011.
