摘　　要：为了深入分析深圳市城市地下空间开发的适宜性,本文在系统归纳深圳市地质环境、地表环境、经济发展及地质灾害等特征的基础上,研究了地下空间开发利用适宜性与各因素之间的关系,建立了浅层地下空间开发利用适宜性评价体系,并采用指数标度、层次分析法确定了指标权重,运用综合指数法对深圳市浅层地下空间开发利用适宜性进行了评价。研究结果表明,深圳市浅层地下空间开发利用适宜性评价指标可划分为6大类14个指标,其中工程地质条件、水文地质条件、地质灾害条件和区域发展条件对适宜性的评价结果的影响较大,而地形地貌条件和地质构造条件的影响相对较小。适宜性评价结果共分为适宜、次适宜、一般和较差4种等级,其中适宜与次适宜集中在福田区、南山区和宝安区,且适宜与次适宜的区域总面积占全市约80%,说明深圳市地下空间开发整体适宜性较好。该评价结果可为深圳市城市地下空间发展规划提供理论依据,且评价体系可应用于与深圳市地质条件相似城市的浅层地下空间开发适应性分析中。To assess the suitability of underground space development in Shenzhen we examined various influencing factors,such as geological environment,surface environment,economic development and geological disaster,to establish a suitability evaluation framework for shallow underground space development and utilization.Fourteen evaluation indicators under 6 categories(geoengineering,hydrogeology,geohazard risk,development status,topography and geology)were used,and the weight of each indicators was determined by scaling index and analytic hierarchy process(AHP)methods.In the final assessment,each urban area of interest was graded suitable,sub-suitable,average or poor for underground space development,and suitability maps were made which showed that the suitable and sub-suitable zones were concentrated in Futian,Nanshan and Bao’an Districts and accounted for~80%of the total urban area.Therefore,Shenzhen has highly favorable conditions for underground space development.This assessment provided a theoretical basis for underground development planning in Shenzhen,and the suitability evaluation framework developed for Shenzhen can be applied to other cities with similar geological conditions.
