| 摘 要： | 近年来大范围发生在我国北方的沙尘暴与内蒙古草原沙地草地的生态退化有直接关系。长期以来人类对自然生态系统的掠夺性利用造成了沙地草地的退化,即人为原因是主要的,而自然的原因是次要的。在沙尘暴的治理方面,关键要解决自然生态系统恢复演替中牲畜的压力,大面积的土地可借助自然力恢复。文章针对沙尘暴问题产生的原因、治理途径、森林在其中的作用、自然力的作用等问题进行了讨论。

| 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. |
