摘要
概念机理模型和数据驱动模型两类异构水环境模型在编程语言、数据描述、模型结构和开发成果等方面都存在明显差异.为了实现异构水环境模型有效集成,针对两类异构模型的不同特点,采用元数据对异构模型进行统一抽象表达,通过Web Service技术对模型进行封装以提供统一的Web服务,实现异构模型一体化集成,开发了一个水环境决策支持系统原型.研究结果表明,该方法能够有效地屏蔽模型的异构性,提供统一的Web服务,提高了系统的通用性和可扩展性.
Conceptual model and data-driven model are two heterogeneous water environment models,which vary greatly from the other in programming language,data description,model structure,development results,and so on. In order to realize the effective integration of heterogeneous models,metadata was adopted to describe the abstraction of heterogeneous water environment models,and Web Service technology was used to encapsulate models to provide unified web service according to the different characteristics of heterogeneous models. Hence,the integrated integration of heterogeneous water environment models was implemented and a water environment decision support system prototype was developed. The results show that the method can effectively shield the models from their heterogeneity and provide a unified web service,and hence improve the generality and extensibility of the system.
