摘要: 沙漠化灾害是影响重大的全球性灾种之一,其危险度分区评价具有重要的理论与实践意义。本文从沙漠化灾害危险度分区评价的依据和原则出发,制定了其评价指标体系,建立了定量评价模型,以此对我国北方的沙漠化灾害危险度进行了分区评价,共区分出15个沙漠化灾害危险度区,其中包括6个轻度危险度区、5个中度危险度区和4个重度危险度区,并对每个危险度区的基本概况进行了简要说明。

Abstract: Sandy desertification disaster is one of the most improtant disasters in the world. Assessment on the regionalization of its hazard degree has very important significances in theory and practice. This paper, judging by the basis and rules of regionalization assessment of hazard degree of sandy desertification disaster, gives its assessment criteria system, establishes the quantitative assessment model and uses this model to regionalize the hazard degree of sandy desertification disaster in northern China. In the result, it is regionalized into 15 hazard degree regions, which include 6 slight regions, 5 moderate regions and 4 severe regions. At last, basic conditions of every hazard degree region are briefly analysed.

Key words: Sandy desertification disaster, Hazard degree, Regionalization assessment, Northern China
