Professor Gong’s research has focused on the teaching and application of geographic information systems and remote sensing, with particular emphasis on urban water-resource management, groundwater systems, and environmental disaster assessment. Through leadership of major national research projects, including projects under the National 863 Programme, National Key Projects, and the National Natural Science Foundation of China, as well as participation in China–France intergovernmental international cooperation projects, he has contributed to the development of decision-support systems for urban water-resource management and the application of remote sensing technologies to flood-disaster monitoring and assessment. He has authored more than 170 peer-reviewed publications in journals including Water Research, Journal of Systems Science and Information, and Science China, as well as more than ten monographs and atlases, including Urban Water Resource Management Decision Support System, 1998 China Catastrophic Flood Remote Sensing Atlas (Chinese–English bilingual edition), and Groundwater Geographic Information System. His contributions have been recognised through seven Provincial/Ministerial-level teaching and science and technology progress awards. Through sustained research, leadership of national research platforms, international scientific collaboration, and academic service, Professor Gong has contributed to connecting geospatial information technologies with practical challenges in urban water management, environmental protection, and disaster monitoring.
