| Abstract: | Hulunbeier Sand Land is one of the four main sandy areas of China. The last years, due to the natural factors and irrational human activities, especially over grazing, this sand pasture has been deteriorated and desertified severely. Consequently, not only the pasture productivity has been reduced, but also the development of livestock industry has been restricted seriously. This paper analyzed the cause of the sand land engendering and enlarging, at last brings forward the main measures about fathering Hulunbeier sand land and the method to use pasture resources ably reasonably. |
