摘　　要：以贵安新区生态新城为例,在分析研究区地质环境条件基础上,提出了地下空间利用概念模型,建立了基于地下水系统单元的分区、分层地下空间利用适宜性评价体系和评价方法,利用ArcGIS平台对典型岩溶区进行了地下空间利用适宜性评价,提出了针对性的地下空间利用建议。结果表明:(1)地下空间适宜性较好以上面积半地下占36.11%、浅层占44.06%、次浅层占43.94%,半地下空间利用主要受地形起伏程度、地层岩性破碎程度影响,浅层地下空间利用主要受地质构造、地层岩性、地表水系、岩溶发育程度、地下工程建筑影响,次浅层地下空间利用受地下水、岩溶发育程度和构造影响;(2)基于地下水系统单元和ArcGIS平台建立评价方法较为方便实用,评价结果经验证较为可靠;(3)地下空间开发利用过程中应准确划分地下水系统,查清地下水动态,重视涌水、岩溶塌陷等灾害。建立的评价方法及评价结果为典型岩溶区地下空间利用、国土空间规划、地质灾害防治提供借鉴和指导。In recent years,with the continuous acceleration of urbanization in China,the development and utilization of ground space and aboveground space have gradually become saturated,and various"urban diseases"such as traffic congestion,land resource shortage,ground noise are increasingly severe.Therefore,reasonable development and utilization of urban underground space is of practical significance to alleviate the scarcity of urban resources,improve environmental conditions,and enhance the quality of residents'life.Located in a typical karst mountainous area on the plateau of central Guizhou,Gui'an New Area not only faces common problems in its urban development such as insufficient land for human due to the unique karst landform of this area,but also faces many engineering geological problems such as karst collapse,mud and water inrush during the development and utilization of underground space.At present,the utilization of urban karst underground space in Gui'an New Area is still in the early stage of planning and implementation.It is necessary to investigate the structural characteristics of underground space,explore and demonstrate the methods applicable to evaluate the suitability of utilizing underground space in karst areas before the large-scale development of underground space.Based on the planning of constructing urban underground space in Gui'an New Area,this study takes the ecological new town in Gui'an New Area as an example.According to different karst hydrogeological units(waterbearing media),it proposes a conceptual model for underground space utilization through comprehensive geological surveys,engineering surveys,and groundwater dynamic monitoring.This study also establishes a suitability evaluation system and method for utilizing underground space according to different zones and layers with groundwater system units.The suitability evaluation of underground space utilization in typical karst areas has been conducted by using the ArcGIS platform,and targeted suggestions have been proposed.The research
