The evaluation of the utilization efficiency of groundwater resources is influenced by the change of groundwater reserves and soil parameters. In order to improve the utilization efficiency of water resources, this paper puts forward an evaluation method of the utilization efficiency of groundwater resources based on fuzzy probability. Establish the gravity field analysis model of groundwater change, take the soil parameters of groundwater distribution environment, diffusion coefficient, water level height and so on as constraint parameters, analyze the influence of different initial conditions of groundwater distribution on soil parameters, analyze the utilization efficiency parameters of groundwater resources according to seasonal and interannual characteristics, and adopt the method of difference degree evaluation through fuzzy probability characteristic analysis. Establish an evaluation model of groundwater resource utilization efficiency that meets the characteristics of groundwater distribution and its gravity effect, adopt water load model and its surface gravity parameter analysis method, adopt fuzzy feature matching and groundwater load feature detection, and realize the optimal evaluation of groundwater resource utilization efficiency. The test shows that this method is reliable and accurate in evaluating the efficiency of water resources utilization, which improves the efficiency of water resources utilization.
