摘要
通过模拟计算,采用正交试验法和回归分析法对点源参数敏感性在AERMOD模型系统中的影响规律进行分析,得出,各参数敏感性影响规律的排序:排气筒几何高度H>污染源强Qs=排气筒出口内径d>烟气出口温度Ts>烟气出口流量Qv。分析结果对于环境影响评价工作中有目的地收集参数资料具有指导意义,对于数据不准确的参数可以估算其导致的误差,并为工程设计提供依据,进而优化环境影响评价中的大气影响预测工作。
Adopting the method of orthogonal test and regression analysis,the influence law of the parameter sensitivity of point source in the AERMOD model system is studied based on the simulation calculation.Sensitivity of parameters under the point source is arranged as follows：Geometric height of the chimney（H）Emission intensity（Qs）export diameter of chimney（d）Flue gas temperature of exports（Ts）Flue gas flow of exports（Qv）.It plays a guiding role in a focused collection of the relevant information for the environmental impact assessment work.Meanwhile,a reasonable assessment of errors due to not accurate parameters can be made and a basis for engineering design can be provided.Therefore,the forecast parts of the atmosphere of the environmental impact assessment work is further refined.
