Variation regularity of air sulphation rates and control measure in Urumqi

The air quality of Urumqi is improved in the recent nine years with the PM10 and SO2 contents being reduced in different degrees.The airpollution degrees of 2001 and 2003were the most serious and the slightest,respectly.Their contents in the air exceeded the second class of the state environment air quality standard in different degrees.This paper is presented to analyze the variation tendency of air sulphation rate pollution in Urumqi,based on the data of its nineyear air monitoring The study results indicate that the sulphation rates are changed with temporal pro-gression.It means that during the period from November to April of next year,the rates exceeded the standard mentioned above obviously,especially in February.The situations are related to the following two reasons:firstly,these monthes are heating season of the city,a great deal of coal used as the burning material;secondly,the air current condition then and landform feature here are not favourable for the diffusion of the polluted air.Some measurenents are put forth to solve the problems of Urumqi air pollution,such as reducing the sources of air pollution,promoting the clear energy use,perfecting the urban planning,regulating the industrial structure and adjusting the urban layout.
