英文摘要	A typical stagnant air pollution episode happened during October 1 to 10, 2004 in Beijing. Using the method of footprint analysis and the monitoring data for major pollutant (PM10) in this period, detailed process and the source-area of potential influence in this episode were analyzed. Results illustrate that: 1) the diurnal variation of PM10 concentration differs significantly from usual case, and high concentration appears in the afternoons and evenings, 2) the horizontal distribution of PM10 concentration has a pattern as 'the higher in the south and the lower in the north', and 3) the development of the episode is accompanied with obviously extending of the footprint 100-200 km to the southwest of Beijing, suggesting that source emission from the southwest may contribute significantly to this heavy pollution episode.; EI; 0; 1; 135-141; 44
