中文摘要	科尔沁位于我国东北部,地处东北平原向内蒙古高原的过渡地带(42°41＇-45°15＇N,118°35＇-123°30＇E),是受荒漠化影响较重的地区.利用外业调查数据,依据地表形态和生态状况的变化,确定了植被盖度、裸沙地占地百分比和土壤质地3项评价指标,并建立了基于遥感的科尔沁沙质荒漠化评价指标体系,其中裸沙地占地百分比用混合像元分解的方法获得.利用外业调查的数据对该指标体系进行验证,结果表明该指标体系适于研究区域的荒漠化评价.表4参11.
英文摘要	Keerqin sand land is located in the transitional terrain between the Northeast Plain and Inner Mongolia (42°41’-45°15’N,118°35’-123°30＇E) in Northeast China and it is seriously affected by desertification. According to the configuration and ecotope of the earth’s surface, the coverage of vegetation, occupation ratio of bare sandy land and the soil texture were selected as evaluation indexes by using the field investigation data. The evaluation index system of Keerqin sandy desertification was established by using Remote Sensing data, and the occupation ratio of bare sandy land was obtained by mixed spectrum model. This index system is validated by the field investigation data and results indicate that it is suitable for the desertification evaluation of Keerqin.
