摘　　要：文章构建了基于约束条件的城市地下空间综合质量评价方法体系,明确了评价内容与指标,提出了权重计算与指标量化方法,并建立了普通因子、约束因子及最不利判别评价体系。以滨海平原型、内陆平原型和滨海山地型城市为研究对象,分别选取日照市、银川市和深圳市南山区为典型研究区,地下空间综合质量进行评价。研究结果表明:1)日照市浅层地下空间资源质量呈现显著空间分异,高质量与低质量区域面积分别为147.66和103.49 km^(2),占比31.11%和21.81%;次浅层高质量、中等质量及低质量区域面积分别为140.70、225.86和108.40 km^(2),占比29.65%、47.59%和22.76%。2)银川市中心城区浅层(0~15 m)地下资源等级最高区域面积为150.8 km^(2),次浅层(15~30 m)受施工影响,高质量区域减至60.4 km^(2);综合质量较低区域面积较大,浅层和次浅层分别为2338.6和1984.8 km^(2);贺兰山山前地带因地质灾害和区位价值低,开发价值较低,其中文物遗址、水源地和生态保护区为禁止开发区域。3)深圳市南山区地下空间开发整体质量较高,中等质量区域占主导地位。高质量区域集中于深圳大学城、留仙洞等片区,面积约44.16 km^(2),占比26.22%;中等质量区域面积约118.52 km^(2),占比70.38%;低质量区域面积仅0.12 km^(2),占比0.07%。This study establishes a constraint-based framework for comprehensive quality assessment of urban underground space,specifying evaluation components and indicators while developing methodologies for weight calculation and indicator quantification.In addition,a tripartite evaluation system is constructed,incorporating common factors,constraint factors,and critical disadvantage identification.Targeting three urban typologies-coastal plain city(Rizhao),inland plain city(Yinchuan),and coastal mountainous city(Nanshan District,Shenzhen)-the research conducted systematic quality evaluations of subsurface resources.Key findings reveal:1)In Rizhao City,shallow underground space(0~15 m)exhibits significant spatial differentiation,with high/low-quality zones covering 147.66 km^(2)(31.11%)and 103.49 km^(2)(21.81%),respectively.The sub-shallow layer(15~30 m)demonstrates distinct quality stratification(high:140.70 km^(2),29.65%;medium:225.86 km^(2),47.59%;low:108.40 km^(2),22.76%).2)The central urban area of Yinchuan City contains 150.8 km^(2)of premium shallow resources,while sub-shallow quality decreases to 60.4 km^(2)due to construction constraints.Substantial low-quality areas persist in both layers(shallow:2338.6 km^(2);sub-shallow:1984.8 km^(2)).The Helan Mountain foothills show limited development potential due to geological risks and low locational value,with cultural heritage sites,water sources,and ecological reserves designated as restricted zones.3)Nanshan District displays superior underground space quality dominated by medium-grade areas(118.52 km^(2),70.38%),with high-quality clusters concentrated in Shenzhen University Town and Liuxiandong regions(44.16 km^(2),26.22%).Low-quality zones are minimal(0.12 km^(2),0.07%).The findings provide a scientific foundation for differentiated underground space development strategies across heterogeneous urban environments.
