摘　　要：地质环境是影响地下空间开发的决定性因素,尤其在受限因素众多的历史古城区,进行地下空间开发的地质环境适宜性评估至关重要。结合苏州观前街区地质及历史环境选取13个评价指标。基于层次分析法和熵权法相结合的方法计算各评价指标的组合权重,并将模糊综合评价法计算得到的结果通过ArcGIS进行三维可视化评价分区展示。评价结果表明:研究区浅层地下空间开发地质环境适宜性程度高的面积约占18.7%,适宜性程度较高的约占59.1%,适宜性程度一般约占21.2%,适宜性程度差的仅占1.0%;次浅层地下空间开发地质环境适宜性程度高的面积约占11.6%,适宜性程度较高的占比高达76.7%,适宜性程度一般的约占11.7%,无适宜性程度差的空间。Geological environment is the decisive factor affecting the development of underground space especially in historic urban areas with many constraints.It is important to evaluate the suitability of geological environment for the development of underground space.Considering the geological and historical environment of Guanqian district in Suzhou,13 evaluation indexes were selected and each combined weight was calculated based on the combination of analytic hierarchy process and entropy weight method.The evaluation results calculated by fuzzy comprehensive evaluation method were displayed in 3D visualization by ArcGIS.The results show that about 18.7%of the shallow underground space is suitable for development,59.1%of the shallow underground space is sub-suitable,21.2%of the shallow underground space is generally suitable,and only 1.0%of the shallow underground space is poor suitability.About 11.6%of the sub-shallow underground space is suitable for development,76.7%of the sub-shallow underground space is sub-suitable,11.7%of the sub-shallow underground space is generally suitable,and there is no space with poor suitability for sub-shallow underground space.
