宝鸡市农村地区地震灾害人口脆弱性调查研究

Research on Population Vulnerability of Earthquake Disaster in Rural Area of Baoji

我国地震灾害多发,地震灾害损失严重影响人类社会发展,而农村地区居民又是地震灾害的主要承灾体和最大受害者,降低地震灾害人口脆弱性对于区域防震减灾工作至关重要。利用实地问卷调查、层次分析法、加权综合评价法、ArcGIS空间数据分析等方法,对宝鸡市农村地区地震灾害人口脆弱性进行了调查研究和综合评价。结果表明:(1)研究区地震灾害人口脆弱性整体偏高,情况尚不理想;(2)人口脆弱性空间分布存在差异,南部地区整体高于北部地区,其主要原因是南部地区家庭青壮年人员流动较大;(3)地貌类型、区位类型是影响人口脆弱性空间分布差异的主要因素。

There are many earthquake disasters in China,which seriously influence the development of human society. The huge rural areas are the main sufferer of earthquake disasters. Reducing the population vulnerability of earthquake disaster is of great importance in earthquake prevention and mitigation work. This paper investigated and comprehensively evaluated the population vulnerability of earthquake disaster in rural area of Baoji through field survey,AHP,weighted comprehensive evaluation method and Arc GIS spatial data analysis. The results showed that（ 1） The population vulnerability of earthquake disaster in rural areas of Baoji is generally high of the whole country.（ 2） There are differences in the spatial distribution of population vulnerability among the counties in Baoji,the population vulnerability is lower in north than that of the southern region. The main reason is that the young adults mobility is higher in southern rural families（ 3） Geomorphic types and location types are the main factors influencing population vulnerability spatial distribution difference.
