摘　　要：利用1978—2020年新乐市和周边曲阳、行唐、正定、定州、藁城、无极共7个国家地面气象站基本资料、承灾体数据及地理信息数据,构建新乐市大风灾害致灾危险性评估模型,结合经济暴露度构建大风经济风险评估模型,得到新乐市大风灾害致灾危险性和风险评估空间分布特征。结果表明:新乐市大风危险性较高值区分布于东王镇、邯邰镇东部和正莫镇北部少部分地区;新乐市经济暴露度呈中间高,四周低的分布趋势,长寿街道经济暴露度等级为高;大风灾害经济风险等级西部较低,东部较高,高等级区位于中部长寿街道、东部南大岳镇、承安镇、杜固镇、东王镇、邯邰镇和正莫镇东部地区。Based on the basic data,disaster bearing body data and geographic information data of 7 national surface meteorological stations in Xinle and Quyang,Xingtang,Zhengding,Dingzhou,Gaocheng and Wuji from 1978 to 2020,the disaster hazard model of wind disasters in Xinle were constructed.Combined with the exposure of local economy,the risk assessment model of wind disaster based on economy was constructed,and the distribution map of risk assessment of wind disaster in Xinle was obtained.The results show that the high wind hazard values of Xinle are divided into Dongwang Town,Hantai Town and a few areas in the north of Zhengmo Town.The high economic exposure of Xinle in the middle,and the economic exposure of Changshou street is the highest.The economic risk level of wind disaster is lower in the west and higher in the east,and the high level area is located in the east of Changshou Street,Nanda Yue Town,Cheng 'an Town,Dugu Town,Dongwang Town,Hantai Town and Zhengmo town.
