摘要： 把资源环境模型抽象为模型类和模型实例2个层次，提出了基于模型类的模型复合策略。在Visual C++ .net 2003和Windows 2000环境下，用面向对象方法构建了模型类和模型实例，结合流程图实现了模型复合的可视化操作。结果表明，流程图较好地集成了可视化的用户界面和内部的模型复合操作，增强了资源环境模型库管理系统的易用性。

Abstract: Resource and environmental models are made of a two-level model abstraction hierarchy: model class and model instance. A strategy for model composition is proposed based on model class. With Visual C++.net 2003 and Windows 2000, model class and model instance are constructed by object-oriented method. Model composition is manipulated through flowchart. Results show that flowchart can well integrate model composition with Graph User Interface (GUI), and the friendliness of Resource and Environmental Model-based Management System(REMMS) is increased.

Key words: model composition, flowchart, resource and environmental model, model representation
