基于DEMATEL-ISM的城市灾害韧性影响因素研究

Study on Influencing Factors of Urban Disaster Resilience Based on DEMATEL-ISM

提高城市灾害韧性对于城市可持续发展意义重大。在确定城市灾害韧性影响因素的基础上,将DEMATEL(决策试验与评价实验法)与ISM(解释结构模型法)相结合,识别关键影响因素,明晰影响因素之间的作用路径与层次结构,绘制原因结果图,构建多级递阶结构模型,从而直观的呈现关键影响因素及作用路径。结果表明,城市灾害韧性影响因素可划分为7级3阶的多级递阶结构,其中,城市管治能力是最关键的根本影响因素,应急信息完善度是最重要的中间影响因素,经济调节能力是最有效的直接影响因素。

It is of great significance to improve the resilience of urban disasters for maintaining the sustainable development of cities.On the basis of determining the influencing factors of urban disaster resilience,combining DEMATEL(Decision Making Trial and Evaluation Laboratory)and ISM(Interpretative Structural Modeling),identifying the key influencing factors,clarifying the action path and hierarchical structure between the influencing factors,drawing the cause result diagram,building the multilevel hierarchical structure model,so as to intuitively present the key influencing factors and the action path.The results show that the influencing factors of urban disaster resilience can be divided into 7 levels and 3 levels.Among them,urban governance ability is the most critical fundamental influencing factor,emergency information perfection is the most important intermediate influencing factor,and economic regulation ability is the most effective direct influencing factor.Combining the research results with the actual situation of urban disaster resilience,this paper puts forward strategies and suggestions for enhancing urban disaster resilience,thus provide targeted guidance for improving urban disaster resilience.
