Taking north Hubei water resources allocation project as the object, the multi-water resources multi-objective optimal allocation under the background of large-scale water transfer project was studied. The reservoirs in north Hubei were divided into three types: filling reservoir, compensation reservoir and online reservoir. The water resources allocation project in the north of Hubei Province is systematically generalized according to the characteristics of various reservoirs. A multi-water resources multi-objective optimal allocation model with the minimum annual water shortage and the minimum water transfer cost as the objective function was established. The weight coefficient method is used to obtain the pareto optimal set. The multi-objective decision-making method based on interval hesitation fuzzy language and TOPSIS is adopted to evaluate the water shortage and water transfer of each scheme and select the optimal scheme.The results show that :(1) for north Hubei water resources allocation project,the scheme with a weight ratio of 7:3 between water shortage and water transfer is the best in comprehensive evaluation, and the water shortage is valued while the water transfer cost is taken into account. (2) the multi-objective decision-making method of water resources based on interval hesitation fuzzy language set and TOPSIS has been proved to have high stability and feasibility by examples in this paper.
