【摘要】：城市自然灾害脆弱性评估,是加强城市防灾减灾能力建设的基本前提。通过对自然灾害脆弱性相关文献进行回顾梳理并结合四川区域特色,构建出城市自然灾害脆弱性评价指标体系。运用主成分分析(principal component analysis,PCA)和逼近理想排序法(technique for order preference by similarity to an ideal solution,TOPSIS),对比分析了四川省21市州的城市自然灾害脆弱性。结果表明,川西北经济区城市灾害脆弱性程度最为严重,成都经济区灾害脆弱性程度最低,大部分经济区下辖市州的灾害脆弱性状况参差不齐。四川省各地存在明显的区域性城市灾害脆弱性差异。
[Abstract]:The evaluation of urban natural disaster vulnerability is the basic prerequisite for strengthening the capacity building of urban disaster prevention and reduction. Through reviewing the related literature of natural disaster vulnerability and combining with the regional characteristics of Sichuan, the evaluation index system of urban natural disaster vulnerability is constructed. The main component analysis (principal component analysis, PCA) and approximation theory are used. Technique for order preference by similarity to an ideal solution, TOPSIS), compared and analyzed the vulnerability of urban natural disasters in 21 cities in Sichuan province. The results show that the vulnerability of urban disasters in the Northwest Economic Zone is the most serious, the vulnerability of Chengdu economic zone is the lowest, most of the economic areas under the jurisdiction of the city state. The vulnerability of disaster is uneven. There are obvious differences in vulnerability of regional cities in Sichuan province.
