基于ISM-灰色聚类法的历史街区可持续更新评价

Evaluation of sustainable renewal of historic district based on ISM-grey clustering method

在“绿色经济”和“双碳目标”背景下,首先,基于历史街区可持续发展目标,构建了历史街区可持续更新评价指标体系,并通过解释结构模型(interpretive structural model, ISM)确定评价指标之间的层级关系;然后,采用区间组合数有序加权算子(combination ordered weighted averaging, COWA)-灰色聚类法构建历史街区可持续更新评价模型,并将其应用于青岛中山路历史街区可持续更新评价;最后,依据评价结果提出相应建议.研究表明:影响青岛中山路历史街区可持续更新的根本因素是更新计划和政策的制定;该历史街区可持续更新评价综合得分为7.08,其可持续性处于中等偏上水平.

Under the background of“green economy”and“double carbon target”,firstly,based on the sustainable development goal of historic district,the evaluation index system of sustainable renewal of historic district is constructed,and the hierarchical relationship between the evaluation indexes is determined byISM method;secondly,the evaluation model of sustainable renewal of the historical district is constructed by the COWA-grey clustering method and is applied to the historical district of Qingdao Zhongshan Road;finally,the corresponding suggestions are put forward according to the evaluation results.The results of the study show that the fundamental factor affecting the sustainable renewal of the historical block of Qingdao Zhongshan Road is the formulation of renewal plans and policies.The comprehensive score of sustainable renewal evaluation is 7.08,which is at a medium to high level.
