| Abstract: | 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. |
