摘　　要：基于排放清单分析了昆山大气污染物排放现状和地铁施工相关污染源的排放特征,核算了污染物的增量,分析了污染减排潜力,利用空气质量模型模拟了污染物增量对周边PM_(2.5)的影响及减排潜力带来的PM_(2.5)改善效果。结果显示,地铁施工过程污染物排放量高,对城市PM_(2.5)影响显著。昆山在地铁建设施工期,通过加强工业源、移动源和扬尘源管控力度可实现污染物持续减排,PM_(2.5)达标压力相对较小,但PM_(2.5)改善幅度同比明显下降,实现持续改善将面临一定挑战。Based on the emission inventory,the current situation of Kunshan air pollutant emissions and the emission characteristics of pollution sources related to subway construction were analyzed.The pollutant emission increment and reduction potential were estimated.The impactof pollutant emission increment on the surrounding PM_(2.5)andthe PM_(2.5) improvement effect bypollutant reduction potential weresimulatedby air quality models.The results showed that the amount of air pollutants emitted during the subway construction was high,which had a significant impact on urban PM_(2.5).During the construction period of the subway in Kunshan,the continuous pollutant emission reduction could be achieved by strengthening the management and control of industrial sources,mobile sources and dust sources,and the pressure to meet the standard of PM_(2.5) was relatively small.However,the improvement rate of PM_(2.5) had dropped significantly year-on-year,and achieving continuous improvement would face certain challenges.
