简要综述“SARS疫情态势分析”课题组如何组织网络空间信息系统、模拟地理环境、统计数学等学科的专家，用“二尺度时空模型”和自主研制的SARS网络地理信息系统对全国及城市SARS中、长期疫情发展的时空态势分析与预测，并及时公布全国SARS疫情分布状况的研究工作。

This paper summarizes the activities of "Severe Acute Respiratory Syndrome(SARS)spread Trend"project conducted by experts on WebGIS,virtual geographic simulation and applied statistics. The project focuses on analysis and prediction of middle-long term spread trend of SARS with national and metropolitan scopes by developing "2-scale temporal-spatial model"and "SARS Web-GIS".
