Abstract: In this paper, based on the extensive collection of materials of geological and engineering investigation, seven categories of geological problems to be prevented and noted and four categories of geological resources to be protected in Chengdu were systematically collated for urban underground space utilization. The underground space in Chengdu has a depth of 200 m that is divided into four layers: 0−30 m, 30−60 m, 60−100 m and 100−200 m, which differ in geological elements (in terms of geology and geological resources) constraining urban underground space utilization, as well as geological structure in vertical direction. Afterwards, the recommendation that the urban underground space in Chengdu should be developed and utilized by zones and layers was proposed, and the Geological Environmental Atlas of Chengdu for Supporting and Serving Comprehensive Utilization of Urban Underground Space Resources (also referred to as the Atlas
