摘要:

为有效判断城市韧性的发展趋势,构建科学合理的城市韧性度评价指标体系至关重要。首先,基于“压力-状态-响应”(PSR)模型,建立涵盖68个初选指标的城市韧性度评价指标体系;其次,采用信息敏感性和相关性分析优化指标体系;然后,采用CRITIC赋权法和综合指数法确定各指标权重并建立评价模型;最后,以北京市为例,结合区域特点及2010—2021年实际数据,确立包括31个指标的指标体系,分析该城市韧性度的发展趋势。结果表明:2010—2021年,北京市的城市韧性整体呈现上升趋势,城市韧性指数由2010年0.436 7上升至2021年的0.558 6。利用构建的评价指标体系和评价模型分析城市韧性时序演化趋势,可找出城市在应对突发事件过程中存在的薄弱环节,便于相关部门采取有针对性的措施。

Abstract:

In order to make a comprehensive and effective judgment on the development of urban resilience, it is essential to construct a scientific and reasonable evaluation index system of urban resilience. Based on the PSR model, this paper initially established the urban resilience evaluation index system covering 68 primary indicators, and the index system was optimized by information sensitivity and Pearson correlation analysis. Finally, the weight of each indicator was determined by CRITIC, and an evaluation model was developed using the comprehensive index method. Taking Beijing as an example, according to the data from 2010-2021, an index system with 31 indicators was obtained, and the urban resilience was evaluated and analyzed. The results show that urban resilience of Beijing has shown an overall upward trend from 2010-2021, with the index increasing from 0.436 7 in 2010 to 0.558 6 in 2021. The result shows the model can figure out the weak link in the city under emergency with the constructed model and evaluation index system, which is beneficial for the relevant departments to put forward the strengthening-resilience suggestions.
