Research on component-based spatial integrated modeling
基于组件的空间集成建模研究*

On the basis of an analysis on the characteristics and critical issues of the three widely-used spatial integrated modeling approaches that are modular, component-based, and service-oriented, firstly proposed a points of view, which was component-based approach was of greater capability to share and reuse models inside or between research communities. Then described a new scheme of component-based spatial integrated modeling in detail, the main features of which included the structure of integrated models, model interface specifications, model coupling modes, and an infrastructure to support model integration. Discussed the potential advantages of the scheme, comparing with the other component-based approaches. Lastly,designed a spatial integrated modeling system on the foundation of the scheme, and created an integrated model to support emergency response of chemical incidents using the system.
