The Three Gorges reservoir area is an important part of the the upper Yangtze River economic belt. It is very necessary and important to carry out comprehensive, multi-level and regular systematic geological survey. This paper gives a review on the development and progress of geological survey in the Three Gorges Reservoir area based on aerial remote sensing technology conducted in the past forty years, briefly describes the principle and characteristics of the aeronautical remote sensing technology that has been proved to be successive, and sorts out the results obtained by using different technical methods,affirms the important role of aerial remote sensing technology in the field of geological survey, summarizes the problems encountered in practice, and predicts the application prospects of aerial remote sensing technology in the geological survey of the Three Gorges reservoir area. The application and research results show that the aerial remote sensing technology has played an important role in geological surveys such as disaster body identification, ecological environment monitoring and resource exploration on the basis of its advantages such as flexibility, efficiency, detailed survey, and accuracy.
