摘　　要：本研究借助遥感技术和地面实测数据,在初步建立植被盖度、沙丘活动强度等监测指标的基础上,采用内蒙、吉林、甘肃、宁夏,青海、新疆6省(区)草地17000km记录的1000多个地面解译标志和2003年7～8月的MODIS数据,对我国北方的草地沙化状况进行监测,分析了我国北方2003年7个草地类型和各省(区)草地沙化动态趋势及分布,并提出北方草原沙化的控制对策。A study was conducted with remote sensing technology and field investigation on the desertification situation of China's northern grassland, as well as the desertifying trend, and the distribution of seven grassland types in six northern and northwestern provinces and autonomous regions of Inner Mongolia, Jilin, Gansu, Ningxia, Qinghai, and Xinjiang. On the basis of established monitoring index of vegetation coverage and the dune activatin, this paper analyzes the present situation of grassland desertification, and suggests some strategies to obviate the plight.
