江苏新型城镇大风灾害危险性精细化评估
Refined hazard assessments of strong wind disasters at the new urbanizational county scale in Jiangsu Province
摘要
Abstract
The rapid urbanization of new-type urban areas in Jiangsu Province has introduced new challenges for the risk prevention and control of regional strong wind hazards.Taking Jianhu County as the study area,this study integrated meteorological records,historical strong wind documentation,and geographic information system data to develop a refined hazard assessment framework tailored for these emerging urban environments.The findings demonstrate that traditional intensity and frequency metrics with explicit disaster-severity levels markedly amplified the discrimination of town-level hazard indices.The established quantitative hazard assessment models,designed to reflect the systematic and localized nature of strong wind disasters,reliably delineate hazard boundaries for every town.By further incorporating site-specific environmental controls on extreme wind speeds-quantified through water-body distributions and digital surface models,the method successfully downscales hazard indices to individual villages.The refined assessments reveal that six villages located along the northern arc of Jianhu's southern boundary exhibit the highest hazard levels in relation to typhoon-induced strong winds.Quantitative analyses additionally highlight Shanggang Town in the eastern region stands out for its pronounced vulnerability to both tornado and cold wave gusts.关键词
