摘　　要：地下水数值模拟需要大量的监测数据作为支撑,数据的录入耗时耗力,存在出错的可能,且不能第一时间进行实时快速预报。采用VB语言编程技术,以识别和验证后的下辽河平原地下水流数值模型和地下水溶质运移数值模型为基础,重新编译后的MF2K和MT3DMS为内核计算程序,Microsoft SQL Server 2000为数据库,开发了模型与地下水实时监测系统的接口,集成建立了下辽河平原地下水水质实时预报模型,并开发了操作界面下的操作系统,实现了下辽河平原地下水水质的实时预报功能。该系统将地下水实时监控技术与地下水数值模拟技术结合,操作简便、时效性强、出错概率小,能够实时获取地下水水位、水质监测数据,对地下水流场和地下水溶质浓度场的演化进行快速预报。同时,本系统预留了更新接口,可根据逐步积累的地下水监测数据和系统计算数据进行进一步验证,不断提高系统预报的精度。Groundwater numerical simulation requires mass monitoring data as basic support.The input of data requires much time and energy,which may cause fault and could not predict groundwater quality immediately.Using VB language,based on calibrated and validated numerical model of groundwater flow and solute transport of Lower Liaohe River Plain,re-compiled MF2 Kand MT3DMS as calculation kernel programs,Microsoft SQL Server 2000 as database,the interface of real time groundwater monitoring system is established,integration of Lower Liaohe River Plain groundwaterquality real-time forecast model is established,and the operation system is developed,achieving the function of real time groundwater quality prediction in Lower Liaohe River Plain.The system combines real-time monitoring technology with the groundwater numerical simulation technology.It has advantages of simple operation,strong timeliness and small error probability.The system can collect real time data of groundwater level and quality,and predict future groundwater level and groundwater solute concentration immediately.Meanwhile,update interface is pre-set to improve prediction accuracy according to accumulated groundwater monitoring data and calculated data.
