For the analysis of the typical routes typical ship emission characteristics, This study based on the data system of automatic identification system, Collect the selected research discharge parame-ters of the ship, with the reality of ship navigation information, Calculated the Qinhuangdao port--Guangzhou port sailing routes a bulk carrier a cycle emissions listing by the Activity-based approach, and analysis of the different working condition of discharge characteristics of the ship, and raw 2 km×2 km resolution space emission characteristic figure. The results show that the a voyage cycle emission amount of SOX and NOX,and PM10 and PM2.5,respectively 18.88 t、30.87 t、1.85 t和1.69 t. Emis-sion source analysis indicated that the engine is the major source of the ship. Cruise condition is the big-gest emission source in a sail cycle. The port is nearby is the most densely area of ship emission.%文章分析了我国典型航线典型船舶排放特征,以船舶自动识别系统数据为基础,收集整理所选研究船舶排放参数,结合船舶实际航行资料,采用动力法估算了秦皇岛港—广州港航线某散货船一个航行周期的排放清单,并分析了靠港、停泊、港内机动、巡航4个船舶状态下的排放特征,绘制了2 km×2 km分辨率的空间排放特征图.结果表明,该典型航线上典型散货船舶一个航行周期排放的SOx、NOx、PM10、PM2.5总量分别为18.88吨、30.87吨、1.85吨和1.69吨.排放源分析表明从在船舶的主机、辅机和锅炉3种排放源中,主机是主要排放源.航行状态上巡航工况排放量最大;船舶排放污染物的空间分析表明,船舶在进出港口区域是污染物排放最密集的区域.
