Air Environmental Impact Research of Urban Traffic Development - A Case Study

摘要

With the speed-up of urbanization,the number of motor vehicles has increased rapidly,which is the main urban air pollutant source because of too much emitted exhaust gas.Based on the motor vehicle exhaust emissions in Shandong Province in 2006,using trend extrapolation and scenario analysis,predict the motor vehicle exhaust emissions for future planning.The results show that the motor vehicles in 2015and 2020 are 27.52 million and 34.53 million,which is 1.9times and 2.38 times of the motor vehicles in 2006,respectively.For the specific air pollutants from motor vehicles exhaust in 2020,SO2,NOX,PM2.5 and PM10 will reach 28.4 thousand tons,356.7 thousand tons,10.8 thousand tons and 12.2 thousand tons,which will be 3 times,1.2 times,5 times and 5 times of the emissions in 2006.The urban air pollutions caused by motor vehicles exhaust will be very serious.
