【摘要】 介绍了SARS时空分析系统的系统结构、数据流程和功能模块,功能模块包括数据库查询和显示、时间态势分析、空间态势分析、空间风险动态区划、时空过程预测、疫情空间传播机理和参数。通过MapObjects控件把这些模块集成为独立运行的软件,系统实现了SARS时空数据的查询和显示,并采用多个时空分析模型从不同角度对SARS时空传播过程进行分析、模拟和预测。更多还原

【Abstract】 The framework, data workflow and modules of spatial and temporal analysis system of SARS are introduced, the modules, which include query and display of databases, analysis of spatial and temporal situation, dynamic regionalization of spatial risk zone, prediction of spatial and temporal transmission trend, and spatial transmission mechanism and parameter of epidemic, are integrated in a system running independently based on MapObjects. The system implements query and display of SARS spatial and temporal data, and uses spatial and temporal analysis models to analyze, simulate and predict spatial and temporal transmission process of SARS from different points of view.更多还原
