三维数值模型在三江平原地下水资源计算中的应用

Application of 3D numerical value model on the calculation of underground water resources in Sanjiang Plain

依据水均衡原理,充分考虑计算区及各计算单元在开采状态下多年补、排均衡的基础上,利用长系列的水文、气象资料,应用三维模型模拟计算了丰、平、枯水年各计算单元的地下水补给量和可开采量,进而求得了多年均衡条件下全区地下水可开采资源量。

According to water balanced principles,on the basis of excavating situation and provisions and removal balance,this papre fully considered calculation region and each calculation unit,employed long-range hydrology,meteorology materials and made use of 3D model that simulated to calculated provision and excavating quantity of underground water of each calculation unit in a good,an ordinary and dry water year,then proceeded to complete excavating resources quantity of underground water of many years balance condition in all regions.
