当前世界干旱地区荒漠化已成为全球性的环境问题,对人类社会的生存和发展构成严重威胁,其中草场荒漠化问题尤为严重。论述了全球草场荒漠化现状,探讨了草场荒漠化过程及其驱动因素,并对草场荒漠化的评价提出了看法与建议。
Desertification of arid areas is becoming a global problem now, bringing about a serious threat to the existence and development of human beings. Range suffer much more desertification than other forms of land. First of all, based on information newly available, this paper outlines the world status of desertification. Furthermore, the process of range desertifcation and its inducing factors are illustrated. Finally, some suggestions are given towards the establishment of a better assessment system of range desertification.
