摘要：以福建一小型工业区为例，采用AERMOD模型预测该工业区DMF（二甲基甲酰胺）的大气环境容量，以研究
AERMOD 模型在小型工业区大气环境容量核算中的适用性。通过调查工业园区内现有企业拟扩建DMF 排放源和未利用
地块拟建的DMF排放源情况，经过多次调整拟新增的DMF排放源的排放情况，预测受工业区DMF排放源影响的各环境
空气保护目标的DMF 短期浓度限值，叠加后达到环境质量标准短期浓度的100%时所对应的DMF 排放总源强，即为该
工业园区DMF大气环境容量。同时，通过预测结果分析总结DMF排放源的源强、空间分布与环境容量的规律性关系。

Abstract: Taking a small industrial park in Fujian as an example, this paper used AERMOD model to predict the atmospheric
environmental capacity of DMF (dimethylformamide) in the industrial park, in order to study the applicability of AERMOD model
in the accounting of atmospheric environmental capacity of small industrial parks. By investigating the DMF emission sources
proposed to be expanded by existing enterprises in the industrial park and the proposed DMF emission sources of unused plots,
and after repeatedly adjusting the emission of the proposed new DMF emission sources, the DMF short-term concentration limit of
each ambient air protection target affected by the DMF emission sources in the industrial park was predicted. The total source
intensity of DMF emission corresponding to 100% of the short -term concentration of the environmental quality standard after
superposition is the atmospheric environmental capacity of DMF in the industrial park. At the same time, the regular relationship
between source intensity, spatial distribution and environmental capacity of DMF emission sources was analyzed and summarized through the prediction results.
