摘要
为贵州刺梨生产防灾减灾及合理布局提供参考依据,通过对贵州省84个气象台站1971—2010年间6—8月的降水量气象观测数据及2011—2012年贵州省6个地州市20个样地刺梨野外调查和果实采集,建立刺梨干旱灾害风险评估模型,并借助GIS技术完成贵州刺梨干旱灾害风险区划。区划结果表明,重度风险区主要分布在贵州南部地区的册亨、望谟、罗甸县和省东部边缘一带,中度风险区主要分布在省的东部铜仁市、黔东南州大部分县市,轻度风险区主要分布在省的中部贵阳市、遵义地区和黔南州各县市。
The risk evaluation model of drought disaster for R.roxburghii was established by analyzing the precipitation data of 84 meteorological stations during June-August,from 1971 to 2010,field survey and R.roxburghii collection from 2011 to 2012,and the risk regionalization of drought disaster for R.roxburghii was completed with the help of GIS to provide a reference for preventing disaster,reducing damage and rational distribution of R.roxburghii production in Guizhou.The results showed that the severe risk areas include Ceheng,Wangmo,Luodian and Eastern Guizhou,moderate risk areas mainly distribute in Tongren and most counties （cities）of Qiandongnan Prefecture,and mild risk areas are Guiyang,Zunyi region and different counties （cities）in Qiannan Prefecture.
