有机更新视角下的古城地下空间资源综合评价——以绍兴古城为例

Comprehensive Evaluation of Underground Space Resources in Ancient City from the Perspective of Organic Renewal:A Case Study on the Shaoxing Ancient City

城市地下空间是城市更新过程中的重要可拓展国土空间资源,亟需对地下空间资源进行科学评估。从古城保护与发展对地下空间开发利用的诉求出发,本文梳理地下空间协同有机更新的思路,分析影响古城地下空间资源开发利用的相关因素,构建适用于古城或具有历史文保价值的老城区的地下空间资源评估指标体系。并以浙江绍兴古城为实证研究范围,采用层次分析法与空间分析方法,评估古城地下空间开发需求度和适宜性,从资源供需关系角度框定古城地下空间优先开发区域,给出地下空间更新策略与规划建议,为绍兴古城地下空间综合开发利用提供技术支撑。

Urban underground space is an important expandable territorial space resource of the urban renewal.Scientific assessment of underground space resources is urgently needed.Based on the demands of the development and utilization of underground space for the conservation and development of ancient city,sort out the ways of coordinated organic renewal of underground space.This study analyzes the related factors affecting the development and utilization of underground space resources,and establishes an underground space resource evaluation index system which is suitable for ancient city or old town with historical cultural preservation value.Taking the ancient city of Shaoxing as the empirical research area,based on the AHP method and spatial analysis method,the influence factors are selected to evaluate the demand degree and suitability of underground space development of ancient city,proposing the priority development underground area from the perspective of supply and demand relationship.These results offer a proposal of underground space renewal strategy and planning suggestions,and provide technical support for comprehensive development and utilization of underground space of ancient city.
