【摘要】 研究区位于松辽盆地中西部 ,含水层主要为第四纪地层 ,采用迦辽金有限单元法对区内开采层进行了数值模拟和预报 ,为区内小城镇发展的供水问题提供了开采方案。由于边界条件及源汇项等都是经过分析推测的 ,所以随着预报时间的增长 ,预报的可靠性也将降低。更多还原

【Abstract】 The study area is located at the mid west of the Song Liao basin. The aquifer is mainly constituted of Quaternary formations. By using the Galerkin finite element method, a numerical simulation and prediction for hydraulic head have made, and two plans of groundwater mine for water supply to the small towns and cites have presented. Because the boundary conditions and the other elements of the mathematical model(water mine, evaporation and recharge, etc.) have given by statistical analysis, prolongation of predicted period would bring forth corresponding errors.更多还原
