Abstract: In order to support the national strategy for promoting the development of the Yangtze River Economic Belt, China Geological Survey has deployed and implemented the "Comprehensive survey on geological environment of the Yangtze River Economic Belt", for which a management and service system to integrate the information was correspondingly developed. The information system is characterized with loose coupling and high scalability, more flexible and configurable in terms of data aggregation, management, application, two- and three-dimensional integration, as well as information sharing. The system adopts a framework, which comprises auxiliary tools and a main system while incorporates cutting-edge technologies such as data lakes and two-and three-dimensional integration, to control and process multiple data sources through encapsulated interfaces and unified processing. It reduces data dependencies, renders the system more adaptable to the variable operational requirements while improves data processing performance and application efficiency, all of which can provide decision makers with comprehensive information on geological environment and decision basis. The development and improvement of this system will offer vital support for the territorial planning, new urbanization strategies, planning-construction of major projects, geo-hazard control as well as ecological civilization construction in the Yangtze River Economic Belt.
