Thick inversion layer, high strength, stable atmospheric structure, is a prominent feature in Lanzhou basin climate, but also caused the important meteorological factors in Lanzhou urban atmospheric pollutants diffusion is not easy in Lanzhou, in winter.The problem of air pollution in Lanzhou, has always been highly valued by all levels of local government over the years,.In recent years,Lanzhou government take some measures to protect the atmospheric environment,that use of natural gas as a clean energy in industrial production and the life of the residents gradually, centralized heating, the construction of natural gas vehicle filling stations, it is the obvious effect on mitigation of atmospheric environmental pollution.With the development of city economy and population growth, the city residents of a small coal stove use is growing rapidly, especially the rapid increase of motor vehicles in the city, which makes the automobile exhaust emissions rise rapidly, and makes the total energy consumption in the industrial source of 13089700 tons of standard coal in 2010, an increase of 321.7%, than 2001 3104000 tons of standard coal, in Lanzhou. Increased emissions of air pollution in the urban area of Lanzhou, and thus increased the atmospheric pollution in Lanzhou city. Because of the atmosphere can be inhaled particles carried in bacteria, viruses, and carcinogens, easily absorbed by the body and deposition in the lungs and direct harm to human health.
The paper studies air quality pollution degree and annual change , The change of energy structure, The change of water soluble ions in atmospheric aerosols in Lanzhou from 2001 to 2013. Put forward ways to solve and improve the city's air pollution. Thus to provide scientific basis for the comprehensive prevention, control of atmospheric pollutants and the modernization of the city,Also provide the scientific research achievements for urban pollution reduction.
