宝鸡农村地区地震灾害房屋脆弱性空间变化

Spatial Changes of Housing Vualerability from Seismic Disaster in Rural Region of Baoji City

  • 摘要: 基于前人研究成果,以农户为基本调查对象,对宝鸡市农村地区地震灾害房屋脆弱性进行了实地问卷调查。运用层次分析法、加权综合评价法、ArcGIS空间数据分析技术对研究区地震灾害房屋脆弱性进行系统分析,探讨其空间变化规律及影响因素。结果表明:①研究区整体房屋脆弱性较高,东部各区县脆弱性低于西南部凤县、太白县等山地地区;②不同地貌类型区的脆弱性存在显著差异,低海拔平原与低海拔台塬低于其他地貌区;③除东部平原县区外,相对于中心城区的区位对房屋脆弱性不存在显著影响;④高烈度区脆弱性显著低于低烈度区,表明政府的防震减灾政策及民众认知与响应,可能对该类区域较高地震灾害风险及历史地震灾情进行有效的应对。

     

    Abstract: Based on research results of predecessors, the essay took farmers as basic research objects to have a questionnaire survey about housing vulnerability from seismic disaster in rural areas of Baoji. Moreover, the essay had a systematic analysis on housing vulnerability from seismic disaster by use of analytic hierarchy process(AHP), weighting comprehensive evaluation method and ArcGIS spatial data analysis technique and discussed its space variation and influence factors. The research results indicated:1) the overall housing vulnerability of the research area was relatively high and fragility of areas in the east was lower than that in Fengxian County and Taibai County in the southeast; 2) housing vulnerability of different landforms is different, and housing vulnerability of plains and tablelands with low altitude is lower than that of other landforms; 3) Except Pingyuan County in the east, housing vulnerability of central urban areas does not have significant differences; and 4) housing vulnerability of areas with high intensity is significantly lower than areas of low intensity, indicating that earthquake prevention and disaster reduction of the government and cognition and response of the public had a positive influence on the higher risks for earthquake and situation of historical earthquakes.
