摘要
分析了黄河农场地区的降雨、蒸发、地表径流、灌溉和地下水水位常规观测资料,构建了该区的水文地质模型。在此基础上,运用FEFLOW软件建立了黄河农场地区三维地下水流数值模型,用实测资料来识别此模型,运用模型估算出研究区2层潜水含水层的地下水入海量,进一步分析地下水中的营养盐场物质,得出研究区营养盐入海量。
In this paper, a hydrogeological model for the Yellow River Farm area is formulated by analyzing the observed data of rainfall, evaporation, surface runoff, irrigation and groundwater level in the area, the finite element subsurface flow system （FEFLOW） software is then used to etablish a three-dimensional numerical groundwater flow model for the Yellow River Farm area, and the observed groundwater level data are used to calibrate the model. The groundwater discharge fluxes to the sea from two groundwater aquifers in the area are estimated by using this model, and the nutrient concentrations in the groundwater are analyzed to obtain different nutrient fluxes to the sea transported by the groundwater in the study area.
