摘要
GIS与专业领域模型的集成面临着许多挑战,其中之一是GIS要适合专业模型的要求。地下水模拟模型需要一个专业的GIS数据结构,同时GIS应用的快速发展,为地下水资源管理提供了辅助决策功能。本文使用面向对象的方法(Object Oriented approach),建立地下水模拟概念模型和适合于地下水可视化模拟的GIS数据结构,并研究 GIS与地下水模拟模型紧密集成技术。采用面向对象的思想,将数据、模型和用户接口统一集成到同一个GIS系统中,为模型管理和分析创造了充分的灵活性。
Many challenges are associated with the integration of geographic information systems（GIS） in terms of specific model applications.One of them is to adapt models to the environment of GIS. The unique aspects of water resource model require a special approach to the development of GIS data structures. The expanded development of GIS applications for handling water resources management analysis can be assisted by use of an object-oriented approach.In this paper, a conceptual GIS data model is formulated to integrate the modeling problem into an operational framework, based on which, extended GIS functions are developed to implement a tight linkage between the GIS and the groundwater model. Through the object-oriented approach, data, models and users interfaces are integrated in the GIS environment, creating great flexibility for modeling and analysis.
