| 中文摘要 |
| 以中国2002年各省统计年鉴中关于机动车及道路信息的数据为基础,并根据COPERTⅢ模型计算出的2002年中国各省区各种机动车类型在城区、郊区和高速公路3种行驶工况下的排放因子,应用GIS技术建立了40km×40km的高空间分辨率的中国机动车排放源清单.结果表明,2002年中国机动车排放CO、NOx、NMVOC和PM10的排放总量分别为2 815×104、305×104、461×104和111×104t,主要来源于摩托车和汽油小客车的排放.污染物排放量的空间分布显示出其排放集中于经济发达地区,10.8%、2.2%、9.7%和5.3%的国土面积分别排放了84%的CO、55%的NMVOC、48%的NOx和48%的颗粒物,并呈现出东部高于西部、沿海高于内地的趋势,其中长江三角洲、珠江三角洲和京津地区的排放相对较强. |
| 英文摘要 |
| The vehicular emission inventories with high spatial resolution of 40km×40km are developed using GIS technique based on the statistic data from yearbooks about vehicles and roads at provincial level in China for the year 2002,and on the emission factors calculated by COPERTⅢ model for each category of vehicles in urban,rural and highway traffic.The results show that the emissions of CO,NOx,NMVOC and PM10 are 28.15,3.05,4.61 and 1.11 million tons,respectively,principally from motorcycles and gasoline passenger cars.The emissions concentrate on the developed areas and those from 10.8%,2.2%,9.7% and 5.3% of country acreage account for 84% of CO,55% of NMVOC,48% of NOx,48% of PM10 emissions,respectively.The emissions in the east of China and coastal areas are higher than those in the west and hinterland areas.The emission source strengths in the Yangtze River Delta,the Pearl River Delta and Beijing & Tianjin area are the highest. |
