地缘环境分析模型图形化建模

摘要

For the increasing demand for the organization and management of geo-environment analysis models (GEAMs),the graphical modeling of GEAM is studied based on meta-model division and classification of the current GEAMs.The graphical modeling framework is constructed and divided into three modules which are model organization and management,model editing,model validation and operation and the main tasks of the modules are defined.The key techniques of graph semantic mapping and correlating,model validation and operation,model output and loading are deeply researched and analyzed using the idea of object-oriented.A geo-environment unit division model is built based on graphical modeling prototype system of GEAM,which is used to verify the feasibility.%针对日益增加的地缘环境分析模型(GEAM)组织管理需求,在对当前GEAM进行元模型剖分及分类的基础上,重点对GEAM图形化建模进行研究.将图形化建模任务划分为模型组织管理、模型编辑及模型验证与运行3个模块,界定各模块的主要功能,构建GEAM图形化建模框架.利用面向对象思想对图元语义映射与关联、模型验证与运行、模型输出与加载等关键技术进行深入研究与剖析.开发GEAM图形化建模原型系统,并通过对地缘环境单元划分模型进行图形化组建,验证可行性.
