The basin water system is a whole composed of three major processes (hydrological physical processes, biological and biogeochemical processes, and humanistic processes) linked by the water cycle. Research on the theory and methods of the basin water system and its practical application in my country are in the ascendant.
Xia Jun academician team based on water system theory and social hydrology, systematically expounded and analyzed the basic concepts, connotations and basic structures of the urban water-economic society-ecological environment relationship, comprehensively considering policy factors, technical factors and social factors , proposed a theory of urban water-economic society-ecological environment correlation based on social hydrology. Based on the basic concepts, connotations and basic structures of urban water-economic society-ecological environment correlation, a general system of equations describing human processes, hydrological physical processes and biogeochemical processes was constructed, and the constitutive relationship of multi-process processes in urban water systems was proposed and revealed. The mutual feedback mechanism of key elements within the related system is established. Based on the theoretical research on urban water-economic society-ecological environment correlation, and based on the DTVGM distributed hydrological model, system dynamics model, urban water resources ecological and economic value assessment model and urban water system component optimization model under uncertainty conditions, we constructed The urban water-economic society-ecological environment correlation model framework was developed, and a set of urban water system integrated simulation methods were proposed to realize the evolution simulation of urban water system coupling with multiple elements and processes under complex conditions.
Integrated simulation method of urban water-economic society-ecological environment correlation system
In view of the characteristics of abundant water resources, serious water pollution and frequent waterlogging in Wuhan, the urban water-economic society-ecological environment correlation model was applied to reveal multi-factor and multi-process Evolution of Wuhan urban water system under comprehensive influences regularity, scientifically evaluate the role of sponge city construction in urban waterlogging prevention and control in the process of urbanization, analyze the green growth trend of Wuhan City under different climate model conditions, and provide comprehensive control and coordinated development of water, economy, society, and ecological environment in Wuhan City. Provided important scientific basis and technical support.
