摘　　要：以京津冀地区BVOCs排放清单为基础,采用WRF-CMAQ模型模拟与情景分析相结合的方式研究了2018年7月京津冀地区BVOCs排放对O_(3)和PM_(2.5)浓度贡献,解析了北京、邯郸、承德、保定等典型城市不同植被类型BVOCs排放对O_(3)和SOA浓度的影响水平,并应用O_(3)和SOA生成潜势核算结果对模拟结果进行验证.结果显示,BVOCs排放对北京、邯郸、承德、保定O_(3)生成贡献率分别为30.19%、24.77%、35.56%、26.73%,对SOA生成贡献率为2.55%、3.32%、4.17%、3.59%;北京、承德的乔木与果园BVOCs排放对O_(3)和SOA浓度贡献最大,邯郸、保定的草地与庄稼BVOCs排放对O_(3)和SOA浓度贡献最大;数值模拟结果与O_(3)、SOA生成潜势表征的潜在影响基本符合.Based on the BVOCs emission inventory,WRF-CMAQ model was used with scenario analysis to investigate the effects of BVOCs emissions on O_(3)and PM_(2.5) in the Beijing-Tianjin-Hebei region in July 2018.The effects of BVOCs emissions from different vegetation types on O_(3)and SOA concentrations in Beijing,Handan,Chengde,Baoding and other cities were quantitatively analyzed,which was verified with the O_(3)and SOA formation potential method.As the results showed,the contributions of BVOCs emission to O_(3)in Beijing,Handan,Chengde and Baoding were 30.19%,24.77%,35.56%and 26.73%,respectively,and the contributions to SOA were 2.55%,3.32%,4.17%and 3.59%,respectively.Trees and orchards showed the greatest influences on O_(3)and SOA in Beijing and Chengde,while grassland and crops showed the greatest contributions in Handan and Baoding.Additionally,the results of numerical simulation and of potential generation method showed relatively consistent results.
