摘  要：
进入20世纪90年代以来,由于人口的增加和经济的发展,荒漠化问题日益引起世界各国政府、国际组织和科学家的普遍关注。有关荒漠化程度评价的问题已成为当前土地科学研究领域一个新的热点。先从荒漠、荒漠化、荒漠化评价的概念入手,阐述了荒漠化评价的目的意义,进而说明土地荒漠化的原因、荒漠化过程和荒漠化发展程度、速率,自然环境的脆弱性,以及土地退化的原因等。详细介绍了荒漠化评价的国内外现状,着重探讨了以下几个问题:荒漠化评价类型,荒漠化评价原则,荒漠化评价方法,荒漠化评价的分级标准等。由于荒漠化研究是一门年轻的学科领域,许多荒漠化基础理论问题有待发展和完善,特别是荒漠化评价指标体系的建立还明显存在很多不足,有待进行进一步的研究
