| Abstract: | Through the survey in open field and judgement in the room by the photoes of remote sensing,thegrassland desertification type can be divided into two i.e. middle and light degree, The total area is about128300hm2. The main personal factors resulting in the grassland desertification are overstocking, digingfireword,unreasonable grazing system and so on,The grassland desertification control can take biology,manage and engineering measures. |
