摘要:

沙漠化是当今世界干旱、半干旱地区面临的严重的生态、社会和经济问题之一。在查阅大量文献的基础上,详细评述了沙漠化的概念及其在时间、空间、内容、景观、发展趋势、结果上等的内涵;总结了国内外沙漠化的监测评价指标体系、分级及其在世界上的分布;在沙漠化问题争论焦点之一的
沙漠化成因上,综合了各家的观点,归纳为干旱气候和大风的自然原因及不合理的“六滥”人为原因;同时对全球变暖和沙漠化之间的相互关系也做了概述;最后对沙漠化的防治方法、根本途径等方而问题进行了系统的总结。

关键词: 沙漠化, 成因, 评价指标体系, 全球变暖, 防治对策

Abstract:

Desertific;ation is one of the most serious ec;ologic;al} social and economic; problems in arid and semi一arid regions in the con-
temporary world.  Based on referring to a large amount of literature we have narrated and(ommented the concept of desertification in

nally summarized as natural reason and artificial reason such as drought climate, gale and unreasonable human being's”six excesses"
activities.  Simultaneously controlling methods, basic  we have outlined the interaction ways of desertific;ation and some
Between global warming and desertification. In the end, the preventing and questions like these have also been summarized systemically
