Rational development and utilization of urban underground space has become an important measure to alleviate the contradiction between supply and demand of land resources, improve urban capacity and optimize urban layout. Underground space is an important part of the geological environment because of its natural resources. Unreasonable development will lead to geological environment problems. In this paper, combined with the actual situation of Dalian City, on the basis of comprehensive analysis of geological environment conditions, eight indicators are selected from the aspects of topography, engineering geological conditions, hydrogeological conditions, geological hazards, ecological factors and human activities to construct the hierarchy model of suitability evaluation for underground space development in Dalian City. The analytic hierarchy process and comprehensive index method are applied to the evaluation. The results show that: the suitable area, secondary suitable area, less suitable area and unsuitable area are 3812.58km2, 5430.91km2, 2711.38km2 and 1659.06km2, accounting for 28.00%, 39.89%, 19.92% and 12.19% respectively. The evaluation results can provide the basis for the future development and utilization planning of underground space in Dalian city.
