摘要
自然灾害是致灾因子和承灾体脆弱性相互作用的结果,前者是外因,后者是内因,因此脆弱性是承灾体本身具有的内在属性。在界定了脆弱性内涵和构成的基础上,以统计参数为基础,分析了京津冀都市圈的自然灾害脆弱性指标体系和区域差异,并结合近年来区域自然灾害损失统计数据,讨论了京津冀都市圈的灾害类别、受灾方式及自然灾害特性。研究表明,京津冀都市圈10市的应对-恢复能力和敏感性发展具有同向性,两者的相对发展速度是影响脆弱性的关键因素;区域系统脆弱性对自然灾害影响很大,且在不同灾害条件下,发挥关键作用的脆弱性指标不同;张家口、承德等市自然灾害损失惨重,农业生产规模大、防灾能力差是主要原因。
Natural disasters are the result of interaction between disaster-causing factors and hazard affected body vulnerability. The former is the external cause. The latter is the internal cause. Therefore the vulnerability is the intrinsic attribute of hazard affected body. Based on the clear definition and connotation of vulnerability, natural disaster vulnerability index system and regional difference of Beijing-Tianjin-Hebei metropolitan region were analyzed in terms of the statistical parameters, and with the help of the regional natural disaster loss data, the types and characteristics of disasters in Beijing-Tianjin-Hebei metropolitan circle were discussed. Study shows that, the sensitivity and response-recovery ability development in 10 cities of Beijing-Tianjin-Hebei metropolitan circle is synchronic. So the relative development velocity of the two aspects is the key factor that affects the vulnerability. Regional system vulnerability has great influence on natural disasters. In different conditions, disaster vulnerability indices that play the key role are different. Cities such as Zhangjiakou and Chengde suffered heavier losses in natural disasters, the main reason of which is the large scale of agricultural production and low disaster prevention ability.
