新疆新源县暴雨洪涝灾害风险区划

Risk Zonation of Heavy Rainfall and Flood Disasters in Xinyuan County,Xinjiang

选用新疆新源县34个气象站2010—2019年日降水量、地理信息及社会经济等数据,采用归一化及GIS等方法,结合致灾因子危险性、孕灾环境敏感性和承灾体易损性,得出新源县暴雨洪涝灾害5个等级风险区划图。结果表明:新源县暴雨洪涝灾害风险呈“东—北”分布的趋势,吐尔根乡、吐尔根农场、阿热勒托别镇、坎苏乡与那拉提镇属于洪涝高风险区;阿热勒托别镇、坎苏乡与那拉提镇的大部分区域及71、72团场属于次高风险区;新源县中东部区域为中等风险区;其余区域为次低风险区与低风险区。

This study selected daily precipitation data,geographic information data,and socio-economic data in 34 meteorological stations from 2010 to 2019 in Xinyuan county,Xinjiang.Utilizing normalization and GIS methods,coupled with an assessment of disaster risk factors,environmental sensitivity,and and vulnerability of affected populations,a comprehensive 5-level risk zoning map for rainstorm and flood disasters in Xinyuan county was developed.The findings reveal an"east-north"distribution trend of rainstorm and flood disaster risk in Xinyuan county.Turgun township,Turgun farm,Agheletobe township,Kansu township,and Narati township are identified as high-risk areas for flooding.Additionally,significant portions of Ageletobe,Kansu,and Narati towns,along with the 71st and 72nd Regiments,fall within the second-highest risk zone.The central and eastern regions of Xinyuan county are categorized as medium-risk areas,while the remainder exhibit sub-low and low risk areas.
