摘要: 近年来沙漠化问题愈来愈引起人们的高度重视, 因为它是干旱及半干旱地区环境退化的一种重要方式, 直接影响着这些地区农牧业生产和人类生活环境。在我国北方地区的鄂尔多斯草原、乌兰察布草原、察哈尔草原、锡林郭勒草原、科尔沁草原及呼伦贝尔草原等地, 都有不同程度的沙漠化表现。沙漠化使得地表出现风蚀、粗化、片状流沙堆积及密集沙丘的形成与发育。其结果则导致生物生产量的下降、土地滋生潜力的衰退和可利用土地资源的丧失。如不及时采取防治措施和调整土地利用方向, 其发展的速度和后果将会更加严重, 必需引起足够的重视。为此, 必须加强对这方面的研究和治理工作。

Abstract: The Inner Mongolian Ulan Chap Steppe is taken as an example to define the characteristics of the desertification vulnerable environment in this paper. We have Studied the characteristics of modern processes of desertification and the ways of its control in steppe zone. This paper includes the following aspects: 1. The potential natural factors causing deseritification. 2. Factors relating human activities in the development desertification. 3. The characteristics of the changing environment in the processes of desertification. 4. The ways to rehabilitate and control desertifiedland. The writers put forward the strategies for resolving the desertification problem through regulating the orientation of land use and the proportion of agriculture forestry and livestock industry to restore the ecological equilibrium.
