摘要
通过问卷调查,采用基于燃油消耗量的方法估算出天津市2010年农业机械氮氧化物(NOx)和颗粒物(PM)的总排放量.2010年天津市农业机械总保有量为57.5万台,其中种植业机械最大约占52.5%;总动力为588万kW,运输机械占比最大为47.3%.估算出2010年天津市农业机械总油耗(主要为柴油)为6.7万t,其中运输机械耗油量为4.5万t.再根据燃油消耗量估算了天津2010年农业机械污染物排放量,NOx和PM年排放量分别为3470t和303t.
In this paper, particulate matter (PM) and nitrogen oxide (NOr) emissions of agricultural machinery in Tianjin were estimated based on fleet make-up and fuel consumption from a survey questionnaire. In 2010, total count of agricultural machinery in Tianjin was approximately 575000, 52.5% being planting machinery. The total power of all agricultural machinery was approximately 5.88 million kilowatts, while transport machinery had the greatest share of 47.3%. Total fuel consumption of agricultural machinery in Tianjin was estimated as 67000 t; over-half of it was by transport machinery (45000t). The annual PM and NOx emission estimates from agricultural machinery in Tianjin were 303and 3470tons, respectively.
