摘要
选用长时间平衡条件下的箱式模式和积分均值法修正的高斯模式在风速、大气稳定度联合频率基础上对石家庄市区SO_2的面源和点源的长期平均浓度进行计算。计算值和实测值比较吻合,从而验证了本方法在经济开发区及城市大气污染预测中的实用性。结合降雨、逆温等因素对计算结果进行了分析。
In this paper the long-time average concentrations of SO_2 for area and point sources in Shijiazhuang city have been calculated based on joint frequency for wind speed and atmospheric stability by selecting box dispersion model equilibrated for long time and Gaussian dispersion model revised by integral average quantity method. The coincidence of calculated and monitored values is good, thus the feasibility of this method was proved in the forecast of atmosphere pollution in economic developing area and cities. Combined with the factors such as rainfall, temperature inversion and others ,calculated results were analysed.
