空间资源保护视角下中小城市地下空间治理模式和策略探索——以丽江中心城市为例

Governance Mode and Strategy Exploration of Underground Space in Small and Medium Cities Based on Perspectives of Space Resource Protection:A Case Study of Lijiang City,China

为推进中小城市地下空间高水平治理和高质量发展,缓解城镇建设用地紧张,提升综合承载力、公共空间品质和增强城市韧性,结合丽江中心城市现状特征,探索与内涵式、集约型、绿色化、智慧化地下空间相匹配的中小城市地下空间治理思路,提出“协调要素-优化结构-保障功能-实现价值-保障机制”的地下空间治理路径。最后,探索性提出以地下水和历史文化保护优先,推进地下空间绿色化和人文化;以点轴形态、浅层开发为主的模式,推进空间集约高效发展;以地下市政、交通和安全设施为重点,增强地下空间安全和韧性;以地下空间用途管制和地下空间“一张图”建设,推进中小城市空间治理智慧化。

A case study is conducted on Lijiang city,China,and the underground space governance concepts for smalland medium-sized cities that match the conformal,intensive,green,and intelligent underground space are explored.This study was performed to promote the high-level management and high-quality development of underground space in small-and medium-sized cities,alleviate the shortage of urban construction land,improve the comprehensive carrying capacity and quality of public space,and enhance the resilience of the city.Furthermore,an underground-space governance path based on the"coordinating elements-optimizing structure-guaranteeing function-realizing valueguaranteeing mechanism"is proposed.Finally,the following suggestions are proposed:(1)Groundwater as well as historical and cultural protection should be preferentially considered to promote green underground space and human culture.(2)The development mode of point-axis form and shallow development should be considered as the key factors in promoting intensive and efficient space development.(3)Underground municipal,transportation,and safety facilities should be emphasized to enhance the safety and resilience of underground spaces.(4)Underground space control and"One-Map"construction can be used to promote the smart management of small-and medium-sized urban spaces.
