摘要: 利用HYSPLIT_4传输、扩散模式,模拟大尺度气象场下的1999年10月～2000年1月珠海地面SO₂浓度变化规律,结果与实测资料对比表明,模式较好地模拟出珠海地面SO₂的浓度水平和变化趋势。模拟结果经过分析还表明,珠海地面SO₂浓度受到广东省其它地区尤其是珠江三角洲地区城市污染源排放的影响;其浓度变化与广州900m高度（或965 hPa等压面）水平风场具有相当好的对应关系。

Abstract: Using Hysplit_4 dispersion model, the work analyzes the variations of surface SO₂ in the Zhuhai region from Oct. 1999 to Jan. 2000. Comparison between observations and model simulations indicate that the model properly simulated the concentration levels and variations of surface SO₂. Model results showed that the surface SO₂ concentrations in the Zhuhai region were influenced by the emissions from other cities around, especially from the cities in the Zhujiang River delta region. The variations of surface SO₂ in the Zhuhai region were in good correlation with the wind at 900-meter altitude over Guangzhou city.
