Abstract: Solving the increasingly prominent problem of the contradiction between supply and demand during the peak season of geothermal water resources in the process of distribution, and providing a scientific basis for the management of geothermal water resources in hot spring tourist resorts. Based on the actual water supply and consumption, social economy and number of residents and travelers in Wentang Town of Yichun City of Jiangxi Province over the years, the water resource coefficient and model parameters of the planning level year were determined, and the Multi- objective programming was used to reflect the social and economic benefits in the allocation of geothermal water resources. The optimal allocation model is used to study the daily maximum water supply in Wentang Town in peak water season and low water season. The daily maximum water supply in the peak and the low water season saves 4 725.86 m³ and 2 493.55 m³ of geothermal water resources respectively. The domestic water consumption of the residents of Wentang Town in the planning year is basically met, and the waste phenomenon in the storefront and hotel industry is improved, and the reasonable service industry is satisfied. Compared with the original water supply scheme, the optimized allocation scheme has been effectively improved in terms of social, economic and comprehensive benefits. The optimal allocation model based on multi- objective programming solves the problem of unbalanced supply and demand of Wentang geothermal water resources to a certain extent, and serves the sustainable development of geothermal water industry.
