摘    要:模型库在水污染控制规划地理信息系统(WPCPGIS)中占据非常重要的位置,它使得系统具有对水环境进行模拟、数据分析、预测,并提出实质性的决策方案等功能.以GeoMedia为系统的开发平台,Microsoft Acess作为数据库软件,用VB计算机语言作为系统开发语言进行编程,着重对系统模型库建设进行研究,并将研究成果应用于三峡库区的大溪河水污染控制规划中,较好地对水环境系统和规划方案进行模拟,为规划人员和决策者提供了污染源分布及排放强度、河流污染负荷、水质状况、水体环境容量、规划水平年水质预测情况、各规划方案的经济技术比较等众多决策信息.模型的计算结果也在GIS中以数字地图的形式直观地显示出来,使得WPCPGIS能够直接用于水污染控制规划决策.

关 键 词:模型库  水污染控制规划  地理信息系统

Abstract:Modelbase(MB) takes an important role in Water Pollution Control Planning Geographic Information System(WPCPGIS),which endows the system with functions of water environmental simulation,data analysis,predicting,and providing feasible advices.Modelbase(MB) is the focus of this paper,with VB as the programme language,GeoMedia as the system developing platform and Microsoft Access as the database software.At the same time,the WPCPGIS Modelbase is applied in the water pollution control planning of Daxi River in the Three Gorges Reservoir Region,the water environment system relatively is simulated well,provicling planning-maker and decision-maker numerous useful informations:the distribution of pollution source,the situation of water quality,the environmental capacity of water,the situation of water quality in designing year,etc.The result of Modelbase can also be visually displayed in the digital map of GIS,therefore WPCPGIS can be directly applied to the decision-making of Water Pollution Control Planning.
Keywords:modelbase  water pollution control planning  geographic information system(GIS)
