| 摘 要： | 利用多源遥感数据，选取危险性、脆弱性、区域综合防范能力因子构建风险评估指标体系。通过H-AHP方法（犹豫层次分析法）确定指标权重，利用图层叠置法评估模型计算得到高温热浪风险等级空间分布。结果表明：雅万高铁沿线区域高温热浪风险具有明显的空间差异。总体而言，北部地区风险高于南部地区，西部地区风险高于东部地区。高风险区域主要集中在印尼首都雅加达，中高风险区域主要分布在雅加达边缘郊区、勿加泗市和万隆市，中部地区风险相对较低，形成典型的两边高、中间低的“V”型分布。该区域高温热浪风险整体处于中等水平，中等级风险面积占比将近50%，除雅加达市、勿加泗市、万隆市和芝马墟市外，其余各县均有一半甚至超过一半的区域处于中等级风险水平。低风险水平区域面积占比最少，仅为8.10%，主要分布在靠近爪哇海的卡拉旺县北部地区，以及森林覆盖度较高的万隆县西南部和万隆西县西南部地区。文章提出了一种基于遥感进行高温热浪风险评估的方法，可为“一带一路”沿线国家高温热浪风险评估提供新思路。

| Abstract: | Since heat wave is currently one of the most important meteorological disasters, it has a significant impact on residents' health and social economy. The accurate identification and assessment of heat wave risk is an effective means to deal with this problem. In this paper, the hazard, vulnerability and regional comprehensive prevention ability factors were selected as the indexes for evaluating heat wave risk. The index weight was determined by the H-AHP method, and the spatial distribution map of the risk level of heat wave was calculated by the graph cascade method. The results show that there is a significant spatial difference in the risk of heat wave in the regions along the Jakarta-Bandung High-Speed railway. On the whole, the risk in the northern region is higher than that in the southern region, and the risk in the western region is higher than that in the eastern region. The high-risk areas are mainly concentrated in Jakarta, the capital of Indonesia. The medium-high-risk areas were mainly distributed in Jakarta's peripheral suburbs and Bandung City. The low-risk areas are distributed in the central region, forming a typical V-shaped distribution being high on both sides and low in the middle. The overall risk of heat wave in this region is at a medium level, with the medium-level risk area accounting for nearly 50%. With the exception of Jakarta, Bekasi, Bandung, and Cimahi cities, half or even more than half of the other counties are at medium-level risk. The area with low risk level accounts for the least, only 8.10%, mainly distributed in the northern part of Karawang county near the Java sea, and in the southwest part of Bandung county and West Bandung county with high forest coverage. In this paper, a method of heat wave risk assessment based on remote sensing is proposed, and spatial social and economic data are used, providing a new idea for heat wave risk assessment for countries along the Belt and Road region. |
