立足于国家军民融合发展战略，城市地下空间的建设理念与实践路径面临着新的机遇，现阶段的“平战结合”利用机制有待进一步完善和优化。面向新时代城市地下空间产业建设，系统地阐明了城市地下空间融合发展的基本概念，〖ＪＰ+1〗分析其演进历程与逻辑内涵，并构建涵盖政治经济条件、军事国防资源、地下轨道交通、地下人防工程利用等要素的融合发展潜力量化评估模型。根据公开获取的有关数据，对中国12座典型城市进行融合发展潜力评估与分类。该研究旨在推进新时代下融合发展型的城市地下空间产业建设，文中构建的评估模型可有效辅助城市地下空间建设决策，同时亦可为城市地下空间资源利用规划编制提供经验借鉴。

Established in integrated development, the construction concept and practice path of urban underground space are facing new opportunities, and the current mechanism of "combined civilian and combat" utilization still needs to be further improved and optimized. Based on urban underground space industry in the new era, the basic concept of the integrated development of urban underground space is systematically clarified, its evolutionary history and logical content are analyzed, and a quantitative assessment model of the potential for integrated development covering political and economic conditions, military and defense resources, underground rail transportation, and the use of urban underground space is established. According to publicly available relevant data, 12 typical cities in China are assessed and classified in terms of their potential for integration development. The study aims to promote the construction of an integrated developmentoriented underground space industry in the new era. The proposed assessment model can effectively aid the decisionmaking process of underground space development, and the application results also provide insights for the planning of underground space resources utilization in the cities concerned.
