本文建立了SARS时空动力学传播模型，并应用多智能体技术研究个体尺度上SARS时空传播行为的模拟方法。基于虚拟地理环境系统平台，本文采用Java和VRML开发工具，研发了SARS传播与控制的智能体模拟原型系统，并以SARS在虚拟社区的传播为例，开展了SARS时空传播行为模拟的初步试验以及反映SARS疫情控制效果的参数敏感性分析。

SARS spatio-temporal transmission and control model is established, and multi-agent technology is employed to model the SARS spatio-temporal spreading behavior. Based on the virtual geographic environment platform and applyication of Java and VRML tools, this paper designs and develops a prototype system to carry out agent-based simulation of SARS transmission and control in a virtual community. The rudimentary experimental results demonstrate that the model and simulation implemented in the paper can be used to represent the characteristics and laws of SARS transmission.
