In order to further study the spatial balance of water resources in Henan Province,aiming at the fuzziness and uncertainty of the spatial balance of water resources,this study established a quantitative index system of spatial balance discrimination criteria,calculated the regional water resource load index,matching coefficient of soil and water resources and water use efficiency,and introduced the Gini coeffi-cient to describe the degree of spatial balance of water resources.A robust water resources spatial equilibrium evaluation model was construct-ed to evaluate the water resources spatial equilibrium in Henan province through robust grade calculation,correlation number method to de-termine the uncertainty transformation grade and subtraction set pair potential method to calculate the spatial equilibrium trend.The results show that the load index of water resources in Henan Province in 2020 was 38.996,which was a large load.The load in the north was greater than that in the middle,and the middle was greater than that in the south,and the development potential in the south was the best,and the distribution was extremely unbalanced.The matching coefficient of water and soil resources was 0.544,which varied greatly among different cities.The water use efficiency was relatively balanced.In 2020,the spatial equilibrium distribution of water resources in Henan Province was uneven,and the equilibrium level was Ⅳ.Among the 18 cities,the distribution of equilibrium level was different,and the south was bet-ter than the north.Among them,the spatial equilibrium of water resources in Anyang City was the worst,with a level of Ⅴ,which was com-pletely unbalanced;The spatial equilibrium of water resources of Zhengzhou,Luoyang,Hebi and Xuchang were in level IV,which was rela-tively unbalanced.The rest of the cities were in level III and below,and the balance condition were better.Large regional water resources load,low matching degree of water and soil resources,and large gap of indicators among counties in the region were important reasons for the spatial imbalance of water resources.The overall spatial balance of water resources in Henan Province showed a small positive evolution trend,and the spatial balance of water resources in 11 cities such as Kaifeng showed a positive evolution trend,while the other 7 cities showed a negative evolution trend to varying degrees.
