Abstract:Degradation of grassland ecosystem is so serious in Inner Mongolia of China that it can hardly support its population. The degradation is induced largely by the increase population especially the Han people, after their living styles have been changed from nomadism to fixed settlements. The large increase of domestic animal numbers has led to the degradation in a dead way. To treat such serious grassland degradation and to stop the serious windy dust storm, the wisest way is to help the local people to get rid of poverty. Most of the money need to be spent for the people rather than planting single tree such as Populus spp. Such planting wastes a great deal of money however receive less effects in the stabilization of the soils. Natural processes could be enhanced if the huge animal pressures were lessened. A new model of using a small part of land to care for the large part of the degraded area is given by us.
