In this article, we develop methods for identifying local business and government vulnerabilities to sea-level rise and the natural hazards associated with it. Unlike the fairly large literature on measuring social vulnerability to natural hazards, there are very few papers that discuss methods for measuring local business or local government vulnerability even though businesses and governments are also differentially affected natural hazards. Our goal is to create measures that are easily replicable using readily available data and that are easy to explain to local planners, policymakers, and citizens. We implement our measures of local business and government vulnerability for our study area, Coastal Virginia. We combine those measures with a physical vulnerability measure to identify the areas in Coastal Virginia where planners and policymakers need to more closely examine the potential impacts of sea-level rise on their local businesses and government. While our methods are tailored to Coastal Virginia, they could be easily applied in other areas threatened by sea-level rise. 相似文献

为揭示交通暴露和土地利用层面各因素对新型冠状病毒肺炎(COVID-19)疫情在社区尺度传播风险的影响,以A市315个小区的1 947例COVID-19确诊数据为研究样本,利用ArcGIS平台的地理编码、核密度分析、空间统计和网络分析等方法,基于道路网络、公交网络、城市POI和中国GDP/人口空间分布的公里网格数据,获取有病例小区500m缓冲区范围内表征交通暴露和土地利用的14项具体指标。在此基础上,采用小区的COVID-19确诊人数作为解释变量,同时考虑交通暴露层面变量(路网密度、设施邻近度)和土地利用层面变量(混合度、使用强度),运用经典全局泊松回归和变系数地理加权泊松回归(GWPR)2种方法建立模型并进行实证对比分析。研究结果表明:考虑空间异质性的GWPR模型具有更高拟合优度和解释度;道路密度、公交线网密度、CBD邻近度、建筑密度、人口密度和土地价值与小区COVID-19传播风险呈显著正相关;出入口邻近度、绿地公园邻近度和土地利用混合度变量则在GWR模型中表现出随空间位置的改变呈现显著正负2种影响效果;人口密度、土地价值、绿地公园邻近度和土地利用混合度对小区COVID-19传播风险... 相似文献
