利用地理信息系统技术对中国内地人口流动空间规律进行了初步研究，主要包括：(1)内地城市人口迁移规律，(2)流入北京、广东两地民工流动状况的空间分析，(3)在北京SARS发生期间民工回流的态势等；SARS沿交通线分布特点。在此基础上，将人口流动的空间规律应用于SARS控制宏观决策的不同阶段，为决策者提供参考依据。

This paper introduces the study for population migration in mainland China and its applications to SARS control. This paper analyzes following issues by using Geographic Information System, (1)the characteristics of immigratory population and migratory population in cities,(2)inflow spatial features for migrant workers in Beijing and Guangdong respectively, (3)situation prediction for migrant workers reflunce to Beijing, and (4)spatiallg distributing features for SARS along traffic lines. According to above studies, some elementary information can be given for SARS control decision-making. (1)The cities, where immigratory population are more than or less than migratory population and the situation along the traffic line can be pointed out here, and how to take measures to cut off the disease of spreading in these cities is obvious;(2)The study on migrant workers can provide some advise to the rural SARS control measures, such as quarantine measures;(3)According to phenological statistic and some raw data for migrant workers, some predictions for the rush hour of migrant workers, who inflow Beijing again refluence can be given roughly.
