| 摘 要： | 5.12汶川特大地震给北川县造成重大灾害损失。根据自然灾害系统理论,从孕灾环境、致灾因子、承灾体和灾情4个方面分别选取相关评价指标,通过GIS空间分析得到了北川县5.12地震灾害敏感度、风险度、脆弱度和灾度分布图,采用1.5 km×1.8 km网格为灾害区划基本单元,在MAPGIS软件中进行叠加分析,根据拟定的区划原则,采用基于空间邻域关系的区域合并方法对北川县地震次生灾害区域分异进行分析并进行灾害程度区划,得到4个灾害类型区:1个极重灾区、4个较重灾区、2个重灾区和2个一般灾区。为北川县的灾后重建规划提供科学依据,为加快北川县灾后重建和县域经济可持续发展服务。

| Abstract: | The 5.12 massive 8.0-magnitude earthquake created enormous devastation and loss of life in Sichuan,China.An assessment method of earthquake affected degree and related regionalization in Beichuan County were put forward,being expected to be helpful to the reconstruction of building and economic development after disaster.According to the system theory of natural disaster,assessment indicator system for earthquake damage in Beichuan was established,which was made up of four levels such as disaster-pregnant e... |
