| Abstract: | Based on GIS platform,damages due to natural disasters(mainly floods and droughts) in different municipalities of Gansu province are classified to provide a scientific basis for comprehensive natural disaster risk management.The results show that: 1) damaged areas in different municipalities vary widely,and only in Dingxi,Qingyang,Jiayuguan,Gannan,Jinchang municipalities the classes of damaged area change less from year to year,but in the other municipalities they change more;2) Dingxi and Qingyang municipalities are typical severe damaged areas,Tianshui,Longman,Pingliang and Baiyin municipalities are areas of severe damaged occasionally or moderate damaged,Jiayuguan,Gannan and Jinchang municipalities are slight damaged areas always,Zhangye and Linxia municipalities are moderate or slight damaged areas;in Wuwei and Lanzhou municipalities the disasters change a lot,from slight to severe;Jiuquan municipality is rather special,where the disaster is slight but was severe in 2000. |
