内蒙古和林格尔新区核心区地下空间适宜性评价

本文以内蒙古和林格尔新区核心区为研究范围，利用已有调查数据，基于MapGIS平台，从水文地质、工程地质、不良地质及地貌4个方面选取9个因子组成了地下空间适宜性评价指标体系，采用层次分析法对研究区地下空间适宜性进行了评价。评价结果显示：研究区浅层地下空间较适宜区占总面积99.71%；中层地下空间较适宜区占总面积95.03%；深层地下空间较适宜区分布于研究区东南部，占总面积26.95%，次适宜区大面积分布于研究区中西部区域，占总面积72.27%。研究结果表明：研究区地下空间资源综合适宜性等级基本以较适宜、次适宜为主，区内不同竖向层次与不同区位地下空间资源的适宜性存在差异，资源条件总体上呈现

SUITABILITY EVALUATION OF UNDERGROUND SPACE IN THE CORE AREA OF HELINGER NEW AREA IN INNER MONGOLIA

Based on the existing survey data and the MapGIS platform, this paper took the core area of Helinger New Area in Inner Mongolia as the research object. We selected 9 factors from 4 aspects(hydrogeology, engineering geology, bad geology and landform) to form an underground space suitability evaluation index system, and used Analytic Hierarchy Process to evaluate the suitability of the underground space in the study area. The evaluation results showed that the more suitable shallow underground space and the more suitable middle underground space in the study area accounted for 99.71% and 95.03% of the total area; the more suitable deep underground space was in the southeast of the study area, accounting for 26.95% of the total area. The sub-suitable areas were widely distributed in the central and western regions of the study area, accounting for 72.27% of the total area. This research demonstrate that the comprehensive suitability of underground space resources in the study area is mainly more suitable area and sub-suitable area, and the suitability of underground space resources in different vertical levels and different locations is different in the study area. Overall, the spatial distribution of resource conditions is
