| 摘 要： | 大气污染物排放清单是空气质量模拟和空气污染治理的重要依据.本研究比较分析了两套覆盖江苏省的2017年大气污染物排放清单，即分别由上海市环境科学研究院、江苏省环境科学研究院编制的"长三角清单"和"江苏省清单"，并结合区域空气质量模型CMAQ评估不同清单对长三角地区2017年1、4、7、10月的空气质量模拟的影响.清单比较结果表明，除二氧化硫（SO2）以外，江苏省清单估算的各污染物排放量较长三角清单低.通过与观测数据比较，发现两套清单对SO2、氮氧化物（NOx）、臭氧（O3）和细颗粒物（PM2.5）的模型模拟性能均较好.江苏省清单与长三角清单两者的模拟结果空间分布接近，其中江苏省清单模拟的PM2.5和O3在长三角多数地区略低于长三角清单的模拟结果（1月O3除外）.江苏省清单与长三角清单均能够用于空气质量模式模拟，可为江苏地区的细颗粒物和光化学烟雾污染的控制策略制定提供参考.

| Abstract: | Emission inventories of air pollutants are important inputs for air quality models.This study compared two emission inventories for Jiangsu province,referred to as YRD emission inventory and JS emission inventory,compiled by Shanghai Academy of Environmental Sciences and Jiangsu Academy of Environmental Sciences,respectively.The impacts of emission inputs on simulated PM2.5 and O3 in the Yangtze River Delta (YRD) in January,April,July,and October of 2017 were assessed with the community multiscale air quality (CMAQ) model.The emission estimates of various pollutants (except SO2) by JS emission inventory are lower than those by YRD emission inventory.Both the emission inventories can reproduce observations of SO2,NOx,O3,and PM2.5 with CMAQ.While the simulated PM2.5 and O3 with the two emission inputs are similar in spatial distributions and seasonal variations,PM2.5 and O3 with JS emission inventory are lower than those with YRD emission inventory mostly in the YRD region (except O3 in January).This work shows that both of the emission inventories are good enough for air quality modeling,and to inform policy decision on control of fine particulate matter and photochemical smog pollution in Jiangsu province. |
