广西内河及沿海船舶大气污染物排放清单及特征研究

摘要基于广西船舶数量及类型、船舶引擎功率等数据，以广西壮族自治区为例，通过船舶引擎功率法建立广西2020年内河及

沿海船舶排放清单，探究广西内河及沿海船舶主要大气污染排放量时空分布，并通过大气扩散模型模拟了船舶大气污染物排放

对广西沿海港区大气环境的影响。结果表明：内河船舶中干货船排放占比为35.6%，四等船排放占比为26.07%；沿海船舶中拖

船排放占比为44.16%~49.33%，主机、辅机、锅炉排放占比分别为52.39%、21.43%、26.18%；不同工况下，沿海船舶停泊工况

SO排放占比最高，其余污染物在慢速行驶工况下排放占比最高。2020年广西北部湾海域船舶SO、NO、HC、CO的平均排
