摘　　要：针对宁夏惠农区渠井用水比例失调,导致地下水越过适宜埋深造成次生盐渍化的问题。选择惠农区李岗村为试验区,在概化试验区水文地质条件,建立了水文地质概念模型,采用双重节点方式对地表水地下水模型进行耦合,在每个时间段对两者进行联立同时求解,通过HydroGeoSphere进行模型的计算求解,率定和验证模型中的水文地质参数。并通过建立的模拟模型,适时调整用水比例,得到在生态安全埋深下,渠井用水最优比例。The well-canal water imbalance in Huinong district of Ningxia has led to the problems of groundwater over the suitable depth and soil salinization. In this paper, Ligang village of Huinong district is selected as the experimental zone, the hydrogeological conceptual model is established on the basis of the generalized analysis of the hydrogeological conditions of the experimental zone. The coupling analysis of surface water model and groundwater model is conducted by using double node analysis. The two models are simultaneously solved at the same time for each time period by using HydroGeoSphere and the hydrogeological parameters are cali- brated and verified. In the end, the optimal well-canal water ratio under ecological safe depth is got through the simulation model and timely adjusting the water ratio.
