摘要
本文采用国际上通用的自然灾害风险概念和分析方法,从高温热浪致人体健康风险的构成比发,分别构建了广东省高温热浪危险性指数、暴露度指数和承灾体脆弱性指数(含敏感性指数和适应性指数),在定量化的风险指数基础上尝试进行风险区划研究。结果表明:高危险性区域位于广东东北部、西北部以及中部偏西地区,低危险性区域主要分布在沿海地区;人体健康高敏感性区域主要位于粤北和粤西,珠三角及粤东南沿海地区敏感性相对较低;适应性较高区域主要分布在珠三角地区,其他地区适应性较低,粤东和西南部分地区适应性最低;风险较高区域主要集中在粤东、粤西北和中部偏西及雷州半岛南部地区,风险较低区域主要在珠江三角洲及其以西沿海地区。该风险指数能较好地反映广东省高温热浪致人体健康风险的分布状况。
Research is done on risk regionalization of human health in Guangdong Province caused by high temperature heat wave based on quantitative risk index.The hazard index of high temperature heat wave,exposure index and vulnerability index（including sensitivity index and adaptability index） of hazard-affected body in Guangdong Province are constructed respectively,from the view of the construction of risk of human health caused by high temperature heat wave,applying the internationally used risk concepts and analysis methods of natural disasters.The result indicates that the high hazard region is northeast,northwest and central west of Guangdong,while the low hazard region is mainly the littoral of Guangdong;the region of high human health sensitivity is north and west of Guangdong,while the Pearl Delta and the littoral of southeast of Guangdong relatively possess low sensitivity;the region of high human health adaptability is the Pearl Delta,while others possess low adaptability;high risk lies in east,northwest,central west of Guangdong and south of Leizhou Peninsula,and low risk lies in Pearl Delta and the littoral of its west.The risk index could better reflect the risk distribution of human health caused by high temperature heat wave in Guangdong Province.
