Abstract: Urban geological survey is the basic support and technical guarantee for optimizing urban spatial structure, building smart cities, and improving the livable level of city. A multi-factor urban geological survey system, including space resources, environment, disasters, etc. has been established based on the needs of urban development and construction in the new era. After learning comprehensive experience of foreign developed cities and fully considering of the national policy guiding factors, the standardization construction schemes for eight subsystems of multi-element urban geological survey have been proposed from three dimensions, such as work content, technical methods and application of results. According to the trend of global geoscience development and the characteristics of inter-disciplinary integration era, the future construction of the urban geological survey innovation system has been proposed in this paper, aiming to explore new ways, new ideas and new methods for urban geological surveys.
