摘　　要：对佳木斯市城区内非甲烷总烃分布情况进行了监测。冬季全市非甲烷总烃浓度值为74.9μg/m^(3),夏季全市非甲烷总烃浓度值为74.1μg/m^(3),全年均值为74.5μg/m^(3),冬季略高于夏季。冬季小时均值变化曲线早7时-11时、15时-傍晚19时两个双峰形状,夏季早6时-中午12时小时均值变化曲线呈现单峰形状,13时,出现较高的拐点,然后出现逐渐下降趋势。冬季和夏季非甲烷总烃三日均值最高浓度点均出现在三江商贸城监测点位,其次为迪尔佳报监测点位。冬季最低点出现在环保局监测点位,夏季最低点出现在开发区监测点位。针对佳木斯市非甲烷总烃产生和分布情况,提出了源头控制、过程减量、排放监控等治理措施,减少非甲烷总烃的排放。The distribution of non-methane total hydrocarbons in Jiamusi city was monitored.The concentration of total non-methane hydrocarbons in the city is 74.9μg/m^(3)in winter and 74.1μg/m^(3)in summer,with an annual average of 74.5μg/m^(3),which is slightly higher in winter than in summer.In winter,the hourly mean change curve has two peaks from 7:00 a.m.to 11:00 a.m.and from 15:00 p.m.to 19:00 p.m.In summer,the hourly mean change curve presents a single peak at 13:00 p.m.,when a high inflection point appears,and then a gradual downward trend.The highest concentration point of the three-day average of non-methane total hydrocarbons in winter and summer appears at the monitoring point of Sanjiang Trade City,followed by the monitoring point of Deer Jiabao.The lowest point in winter appears at the monitoring point of environmental protection bureau,and the lowest point in summer appears at the monitoring point of development zone.In view of the production and distribution of non-methane total hydrocarbons in Jiamusi City,some control measures such as source control,process reduction and emission monitoring are put forward to reduce the emission of non-methane total hydrocarbons.
