基于船舶自动识别系统（AIS）和基于活动的方法获取的航速、航行时间和地理信息等参数，建立了2012年大连沿海远洋船舶排放清单。结果表明，2012年大连沿海远洋船舶PM10、NOx、SOx、CO、HC和CO2的排放总量分别为5,785 t、51,451 t、49,437 t、4,677 t，分别为2,010 t和2,885,388 t。约75 μ0%的排放发生在泊位住宿期间，船舶和污染物略有差异。从排放的空间分布可以清楚地看出，港区是船舶停泊的集中地。干散货船、集装箱船、邮轮和油轮这四大类船舶占了90. 9%的柴油机颗粒物，91. 4%的氮氧化物，91. 9%的SOX，91. 5%的CO和91。9%的二氧化碳排放量。对于集装箱和滚装，主机是主要的排放源。90. 0%的总排放量来自主发动机，而超过40。普通货物和巡航的排放中0%来自辅助发动机。
Based on parameters such as speed,sailing time and geographical information obtained from automatic identification system( AIS) and activity-based approach,an emission inventory of ocean-going vessels( OGVs) in Dalian coastal area in 2012 was established.Results showed that the total emissions of PM10,NOx,SOx,CO,HC and CO2 from OGVs were 5,785 t,51,451 t,49,437 t,4,677 t,2,010 t and 2,885,388 t,respectively. About 75. 0% of emissions happened during berth hoteling,with slight differences between vessels and pollutants. It could be clearly seen from the spatial distribution of emissions that the port area was the densest,where vessels berth. The top four types-dry bulk carrier,container,cruise and oil tanker-accounted for 90. 9% of DPM( diesel particulate matter),91. 4% of NOx,91. 9% of SOx,91. 5% of CO and 91. 9% of CO2 emissions. The main engine was the major emission source,for container and ro/ro. 90. 0% of the total emissions were from the main engine,while over 40. 0% of the emissions of general cargo and cruise was from the auxiliary engine.
