摘要:

运用层次分析法结合GIS软件,建立基于下垫面孕灾环境因子的锡林郭勒地区沙尘暴风险评价指标体系,评价锡林郭勒地区3个时间段(1981—1990, 1991—2000, 2001—2010)的沙尘暴风险。结果表明: 30年间锡林郭勒地区沙尘暴风险呈增加趋势,且西部地区高于东部地区。

Abstract:

Xilingol region is one of the major typical steppes and a major ecological barrier around Beijing, however it is located in an ecologically fragile area. Using AHP and GIS technology, An assessment system of sandstorm risk was established based on the underlying surfaces factors. This article analyzed sandstorm risk assessment during the three periods (1981-1990, 1991-2000, 2001-2010) in the Xilingol region. The assessment result showed that the risk greatly changed during the recent 30 years. The risk had a gradually increasing trend and the risk in the western was higher than thatin the eastern at the same period.

Key words: sand storm, underlying surface, hazard-formative environment, risk assessment, Xilingol region
