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

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.
