Abstract: TSP is one of the most important forms of air pollution,in which harmful organic matter can be absorbed and enter the human body resulting in different disease.In this paper,distribution characteristics of organic matter of TSP in Taiyuan city was originally researched.After analysed the samples collected in different function zones of Taiyuan city during heating and non heating seasons.the concentration and distribution of the organic matters in TSP including saturated hydrocarbon,aromatics,non hydrocarbons and asphaltenes are obtained,which shows that: 1)the concentration of organic matter during heating seasons is higher than that during non heating ones.2) the concentration of organic matter is various in different function zones,i.e.,industrial zonecommercial and living zonechemical industry and culture zone.3) the order of concentration of organic compositions is asphaltenesaromaticsnon hydrocarbonssaturated hydrocarbon.4)pollution in Taiyuan city is mainly attributed to burning of coal,gas and industrial release. Since the air pollution of Taiyuan city mainly results from coal burning,which is more serious in winter than in summer,so it is necessary to take efficient measures such as collective heating supply and efficient dust removing methods to control it.Among functional zones,the industrial area of the steel plant is the most seriously polluted region where heavy industrial plants such as the steel plant and the mine machinery factory releasing waste gases to pollute air should be controlled.In addition,little stoves or boiler must be restricted.As the highest content of asphaltene in four organic compositions,the high efficient coat washing equipment should be adopted to retrieve asphat and tar before its trasportation and burning.During transportation,coal should be tightly packed.More efforts should be made in constructing artificial woods to improve the air quality of Taiyuan city.
