自然灾害社会易损性空间分布格局研究——以茂名地区为例

Research on Spatial Distribution Pattern from Social Vulnerability Assessment to Natural Disasters——Based on Maoming

以茂名所辖的2区3市作为研究对象,利用统计年鉴选取了表征研究对象自然灾害社会易损性的9个社会经济指标,采用主成分分析,推出按分值大小从高到低排序的3个社会经济综合指标,对其进行自然灾害易损性进行系统评估,据此得到茂名2区3市自然灾害社会易损性的空间分布格局。研究发现:电白区的自然灾害人口结构社会经济易损性最高;化州市的自然灾害社会保障易损性最高;茂南区的自然灾害社会经济易损性最高。

Taking the 2 districts and 3 cities under the jurisdiction of Maoming as the research object,the paper selects the indicators of social vulnerability to natural disasters by using statistical yearbook Nine socio-economic indicators,using principal component analysis,three socio-economic comprehensive indicators ranking from high to low according to the score size are put forward,and the vulnerability to natural disasters is systematically evaluated.Based on this,the spatial distribution pattern of social vulnerability to natural disasters in 2 districts and 3 cities of Maoming is obtained.It is found that the socio-economic vulnerability of natural disaster population structure in Dianbai district is the highest,that in Huazhou City is the highest,and that in Maonan district is the highest.
