Three-dimensional digital system capable of displaying inundation compensation information of downstream beach area of Yellow River

The invention discloses a three-dimensional digital system capable of displaying inundation compensation information of a downstream beach area of a Yellow River, and the system comprises a beach areasocial and economic information management subsystem and a beach area three-dimensional information display subsystem, which are designed according to the architecture of a data layer, a data accesslayer, a system application layer and a system presentation layer. The information of the beach area social and economic information management subsystem is the basis for the beach area three-dimensional display system to perform inundation statistics, and after the beach area three-dimensional information display subsystem calculates the inundation village, inundation loss statistics and three-dimensional scene display are performed according to the village information stored in the social and economic information management database. According to the method, corresponding decision-making activities can be carried out on the information of the downstream beach area of the Yellow River, a comprehensive, dynamic and visual technical means is provided, scientific, rapid and reliable social and economic influence analysis, disaster loss assessment, scheme optimization and other supports are carried out, and the method has important significance in comprehensively improving the scientificity, accuracy and reasonability of decisions.
