Abstract:
The Yangtze-to-Huaihe River Water Diversion Project (Henan Section) is located in the eastern part of Henan Province, and its water consumption affects many elements of life, including agricultural irrigation, industry, and the environment. The carrying capacity of water resources is incompatible with the distribution of population and cultivated land. There are issues such as low per capita average water per mu, industrial water crowding out other water uses, and complex engineering measures, coupled with the congenital scarcity of water resources. The contradiction between supply and demand for water resources in the water-affected area is tense, and the paradox between people and water is growing. However, the current researches rarely take the human-water relationship into account in the optimization goal, and the configuration results may cause human-water disharmony. The project has been opened to water, but there is currently no supporting allocation system in the Henan section, and how to incorporate the concept of harmonious water allocation into the optimal allocation system of water resources to alleviate the contradiction between people and water in the water-affected areas, improve the ecological environment, and drive economic growth is an urgent problem to be solved.To strengthen the unified allocation of water resources, based on the model of separate development of Spring Boot and Vue front-end and back-end, the water resources allocation system of the Henan section was designed and developed by Tianditu API, WebGL, Echarts, Lingo and other technologies. Among them, the front-end framework was built by Vue framework, Tianditu API, WebGL, and Echarts technology, and the main functions are model parameter input and data visualization. The back-end framework was built using Spring Boot and Lingo technology, and the main functions are the solution of water resource allocation models and data persistence. The advantage of this front-end and back-end development of system separation is that the development weight of the entire project is shifted forward, and the front-end and back-end developers can develop together, to improve the efficiency of system research and development, truly realizing the decoupling of the front-end and back-end of the system, separates dynamic and static resources, improves the scalability of the system, and facilitates the secondary development of the water resource allocation system.The system design ideas and implementation process were discussed from the three perspectives of system design, functional interface, and key technology, to realize the functions of geographic information service, supply and demand water forecast, annual harmonious allocation of water resources, monthly scheduling scheme of engineering, and scheduling of abnormal working conditions, and realize the visualization of water allocation, intelligent operation scheduling, and integration of cross-basin water diversion management and control.The establishment of the water resources allocation system of the Henan section has improved the level of refined management of water resources in the receiving area, solved the multi-source, multi-target, and multi-department allocation problem of the cross-basin water diversion project, and provided effective technical support for the efficient utilization of water resources in the Yangtze to Huaihe River Water Diversion (Henan section).
