中文摘要：

通过运用ADMS-Urban模型,以ArcGIS和线性规划模式为辅助,研究了某城市区域在两种不同气象条件下的环境容量的最优化分配方案,同时对不同气象条件下的SO2的环境容量优化值进行了测算与分析,并模拟出污染物的浓度分布.结果表明,气象条件对环境容量的优化分配方案以及污染物的浓度分布有较大影响,但对优化分配后的环境容量影响一般.

英文摘要：

ADMS-Urban model can simulate the diffuse process of atmospheric pollutants which come from industrial areas, civilian facilities and traffic areas. Therefore, ADMS-Urban model has been widely used in many fields including environmental engineering. With the help of ArcGIS and linear programming method, ADMS-Urban model is adopted to research the optimal allocation of environmental capacity with different meteorological data in a certain urban area. Then the optimized environmental capacity of S02 is calculated and analyzed in two circumstances. Finally, the model is used to simulate the distribution of pollutant concentration. The results show that meteorological condition does not influence the optimized environmental capacity a lot in urban area, but actually make great influence on optimal allocation of environ- mental capacity and distribution of pollutant concentration.
