摘　　要：对京津区域１９８０─１９９２年间能源利用状况进行分析，并通过模式计算该区域大气污染物的扩散规律。结果表明，大气污染物随能源利用增加而增加，其增加速率ＮＯ_ｘ大于ＳＯ_２．经预测，至２００４年京津地区ＳＯ_２排放量增加１１．４０％，ＮＯ_ｘ增加５６．８０％。由于气象和地形条件所致，该区域内不利于大气污染物远距离输送，这使用型区域内物料平衡计算可以简化。The dispersion of air pollutants has been studied by analyzing and simulating the situation of energy consumption from 1980 to 1992 in Beijing-Tianjin-Bohai region. The concentration of air pollutant was in direct proportion to the consumption of energy. The emission of SO_2 in 2004 in this region will rise 11. 4 % and the concentration of NO_x increase about 56. 8 % based on the results. The climatic and topographic conditions in this region are unfavorable to long distance transportation of air pollutants.
