摘要
城市地下空间利用是拓展城市发展空间、优化城市空间布局、解决城市问题、提高城市治理能力及实现城市高质量发展的有效途径之一,对地下空间资源进行全面评价是保障地下空间安全利用的前提。文章系统分析了城市地下空间的资源属性及评价现状,梳理了目前主要的城市地下空间资源评价方法及其在不同城市的应用进展。当前,城市地下空间资源评价主要采用层次分析法和专家打分法对评价指标权重赋值,对地下空间资源开发利用的适宜性、资源容量、质量、价值及潜力进行评估,特点是评价目的多样、内容广泛、指标选取各具特色,存在的问题主要是权重赋值主观性强、评价模型不完善等。在对城市地下空间资源评价现状分析的基础上,从地下多种资源协同评价、全空间三维评价、地质环境响应评价三方面分析了城市地下空间资源评价的发展趋势,这对城市地下空间资源评价及开发利用具有一定的参考价值。
Utilization of urban underground space resources(UUSR)is one of the most effective approaches to expand urban space,optimize urban structure,solve city problems,improve city management and achieve high-quality development.The comprehensive evaluation of underground space resources is the premise of ensuring the safety utilization of underground space.This paper systematically analyzes the resource attribute and evaluation status of UUSR,and sorts out the major evaluation methods of UUSR and the application progress in different cities.It shows that the current evaluation of UUSR mainly adopts analytic hierarchy process and expert scoring method to assign value to the evaluation indexes,and to evaluate the exploitation and utilization of suitability,resource capacity,quality,value and development potential of UUSR,which is characterized by various evaluation purposes,extensive content and distinctive indexes selection.However,there are also some problems,such as strong subjectivity of weight assignment,and imperfect evaluation model,etc.Based on the analysis of urban underground space resources evaluation,the trend of UUSR evaluation is analyzed from the perspectives of collaborative evaluation of various underground resources,three-dimensional evaluation of whole space,and response evaluation of geological environment,which could provide valuable reference for the UUSR evaluation and utilization.
