中文摘要	以地理信息系统(GIS),遥感(RS),全球定位系统(GPS)3S技术为主要手段,采用科尔沁左翼后旗2000年7月和2007年7月的两期四景Landsat/TM遥感影像数据,提取其植被覆盖度值,并根据荒漠化程度对其进行分类,分别是:未荒漠化(Fc>0.6),轻度荒漠化(0.3
英文摘要	In this paper,we used Landsat/TM remote sensing image data of Horqin Left Wing Rear Banner in July 2000 and 2007, extracted the value of vegetation cover. Based on their values, degrees of desertification were classified including:no desertification(Fc > 0.6), mild desertification(0.3 < Fc < 0.6), moderate desertification(0.1 < Fc < 0.3) and severe desertification(Fc < 0.1), the status and dynamic information of desertification change in the study area were obtained. The area statistics of different types of desertification and the transfer area array analysis showed that the total area of desertification was reduced by 521.86km2 from 2000 to 2007 in the study area, severe and moderate desertification were reduced, mild and non-desertification were increased, the total extent of desertification was in a decrease trend, meanwhile, the causes of these changes were analyzed, results showed that under the natural background of reduced rainfall and increased temperature, the implementation of desertification prevention and control measures have played an important role
