基于城市功能需求韧性城市评价指标体系研究

Research on Resilient City Evaluation Index System Based on Urban Functional Requirements

摘要:

为了构建一套能体现“抵御、恢复、适应”城市韧性全过程的指标评价体系，基于国内外的研究成果，归纳出经济、设施、生态、管理、社会5个评价指标维度。在此基础上分析遭受灾害后城市功能曲线变化情况，将城市受灾过程划分为灾前、灾时、灾中、新阶段4个阶段，分析不同阶段下城市所需体现韧性功能，为评价指标选取提供方向。采用层次展开法，构建具有普适性和全面性的韧性评价指标体系。结合评价指标选取原则和来源，对评价指标进行等级划分，并提出了韧性城市综合指数概念，为韧性城市建设评估提供方法。

Abstract:

To construct a set of index evaluation system able to reflect the entire process of urban resilience of “resistance, recovery and adaptation”, based on the research achievements at home and abroad, five evaluation index dimensions of economy, facility, ecology, management and society are summarized. On this basis, the urban functional curve changes after a disaster are analyzed. The process of urban disaster is divided into four stages: before the disaster, during the disaster, in the disaster and the new stage. The resilience functions that cities need to demonstrate at different stages are analyzed. The above analysis provides the direction for the selection of evaluation indexes. The hierarchical expansion method is used to build a resilience evaluation index system with universality and comprehensiveness. Combined with the principles and sources of selecting the evaluation indexes, the evaluation indexes are classified into different grades, and the concept of comprehensive index of resilient city is proposed, which provides an approach for evaluating the development of resilience cities.
