广西干旱灾害暴露度时空变化特征

利用2004-2015年广西干旱灾害的灾情数据和社会经济数据,从灾害发生的人口暴露度、农作物暴露度和经济暴露度3个方面分析干旱灾害暴露度的时空变化特征。结果表明,2004-2015年广西干旱灾害多年平均人口暴露度、农作物暴露度和经济暴露度分别为266人/km^2、43.8万hm^2、331.4万元/km^2,其中多年平均人口暴露度为桂中〉桂东〉桂南〉桂北〉桂西、多年平均农作物暴露度为桂中〉桂北〉桂西〉桂东〉桂南、多年平均经济暴露度为桂中〉桂南〉桂东〉桂北〉桂西,广西干旱灾害多年平均人口暴露度、经济暴露度总体呈显著增加趋势。...

According to historical flood disaster data and social economic data in Guangxi from 2004 to 2010, we analyzed the characteristics of disaster exposure from aspects of disaster area, population exposed to disaster, and crop exposed to disaster. The results showed that from 2004 to 2015, the average population exposure, crop exposure, economy exposure were respectively 266 person/km2, 438 thousand hm2 and RMB 3.31 million/km2, and the average population exposure and economy exposure were the highest in central Guangxi, the level of economy ex
