摘要: 地下水模型是进行地下水模拟与评价的主要工具。文章按照J2EE标准,在提高软件的可扩展性、可维护性和代码利用率的指导思想下,以中间件技术应用框架为基础,以三维地下水模型为核心,采用MVC软件设计模型,开发了地下水模型中间件,建立了基于Web的地下水模拟系统,并利用WebGIS技术可视化地下水模型结果。系统缩短了模型建模周期,提高了模型的使用效率。Abstract: Groundwater model is a key tool of groundwater management.It is widely used in the field of groundwater management.According to standard J2EE and satisfying expandability and maintainability of software and high rate of code reuse,this paper uses the frame of middleware technology style as a base and three-dimensional groundwater models as a core,adopts MVC software design model,develops groundwater simulating middleware,establishes Web-based groundwater modelling systems,and uses the WebGIS technology visualization of groundwater simulation.By using this system model,building period is shortened and the model running efficiency is enhanced.
