摘　　要：为评估不同空气质量模型(AERMOD、ADMS和CALPUFF)在复杂地形-气象场条件下的干湿沉降模拟效果,利用上述模型模拟我国西南某代表性山地的医废、垃圾焚烧项目的二噁英环境影响,并通过土壤实测数据进行模型分析验证.结果表明:AERMOD、ADMS和CALPUFF模拟的空气中年均浓度依次为1.53×10^-8~4.14×10^-6,5.23×10^-9~3.28×10^-6和2.66×10^-9~2.59×10^-7ngTEQ/m^3;AER MOD、ADMS和CALPUFF模拟的固定点位总沉降量依次为4.41~285.72,3.07~268.02和0.02~1.35ngTEQ/m^2.在扩散、沉降形态上,CALPUFF的模拟结果与其他两种模型均表现出较大差异,AERMOD和ADMS的沉降形态相似,空气中的扩散形态却存在差异.利用土壤监测值验证模型效果发现,AERMOD、ADMS和CALPUFF的相关系数r分别为0.66、0.70和0.83,CALPUFF的模拟结果在空间分布上表现更为优越,可作为相关项目的布点指导模型.In order to evaluate the modeling effects of different air quality models(AERMOD,ADMS and CALPUFF)on dry and wet deposition under complex terrain-weather conditions,using the above models simulated the impacts of dioxins on ambient environment from the medical waste and waste incineration projects which were in a representative mountainous area in southwest China.The deposition effects were verified by analysis of soil sampling data.The results showed that the annual average concentrations in the air modeled by AERMOD,ADMS and CALPUFF were 1.53×10^-8~4.14×10^-6,5.23×10^-9~3.28×10^-6 and 2.66×10^-9~2.59×10^-7 ngTEQ/m^3 respectively;the results of total soil deposition at the monitoring points modeled by AERMOD,ADMS and CALPUFF were 4.41~285.72,3.07~268.02 and 0.02~1.35ngTEQ/m^2 respectively.The modeling results of CALPUFF showed great differences in both diffusion&deposition patterns,compared to the other two models.The simulated deposition patterns of AERMOD and ADMS were similar,while the simulated diffusion patterns in the air were not.Through the verification of soil monitoring data,it was found that the correlation coefficients r of AERMOD,ADMS and CALPUFF were 0.66,0.70 and 0.83 respectively.The modeling results of CALPUFF were superior in spatial distribution and can be used as the guidance model for related projects.
