APPLICATION EXPLORATION, THEORETICAL AND TECHNOLOGIACL INNOVATION OF GEOLOGICAL SURVEY RESULTS IN COASTAL BEDROCK CITY：TAKING QINGDAO AS AN EXAMPLE

Urban geological work is an important development direction of geological work in the future, and has become an important basic support for urban planning and construction, economic and social development. This paper systematically expounds the positioning, service effect, theoretical and technological innovation of urban geological work in Qingdao, as well as the strategic thinking of future urban geological work of Qingdao. Since 2018, the multi factors urban geological survey project of Qingdao organized and implemented by China Geological Survey Bureau has achieved remarkable results in serving the land and space planning of Qingdao, demonstration of major engineering construction planning, coastal ecological environment protection and restoration, and work of natural resources management center. This work has realized innovation of theory and technology for coastal bedrock urban geological survey. The future development direction of Qingdao urban geological survey is to strengthen the leading role of urban geological services for economic and social development, strengthen monitoring and early warning and realize multi network integration, and effectively solve major geological problems closely related to urban development and urban residents' life.
