The Research On The Relationship Between The City Taxi Type Choice And The Urban Atmospheric Environmental Capacity

Along with the development of our country's automobile industry of and the fast growth of vehicle possessing quantity, motor vehicle exhaust pollution has become the main pollution source in some big cities. In recent years, taxi renewal policies preferring high grade cars were put forward continuously in some cities. But this kind of policies would enlarge the urban air pollution, furthermore, it don't fit the thought of Building a Resource-saving Society. This thesis taking Bejing city as an example studied the relationship between taxi type choice and urban atmospheric environmental capacity. The urban atmosphere environmental capacity and the contribution rates of various pollution sources including taxi exhaust to the atmospheric pollution were accounted. Based on above works some measures to reduce contribution rate of taxi emission to urban atmospheric pollution were proposed. It should provide theoretical bases to the urban air pollution control engineering.
