Abstract: In this paper, according to the special geographical position of the Heping District in Tianjin and the specific situation of nearby monitoring points, the concentrations of PM10, SO2 and NO2were analyzed from 2010 to the first half of 2014. Monitoring data showed that in the past five years the annual average concentrations of PM10 were 0.102 mg/m3, 0.096 mg/m3, 0.104 mg/m3, 0.138 mg/m3 and 0.147 mg/m3, respeictively. The annual average concentrations of SO2 were 0.060 mg/m3, 0.052 mg/m3, 0.051 mg/m3, 0.064 mg/m3 and 0.082 mg/m3, respectively. The annual average concentrations of NO2 were 0.040 mg/m3, 0.046 mg/m3, 0.045 mg/m3, 0.049 mg/m3 and 0.058 mg/m3,respectively. By analyzing and comparing these data, these three kinds of pollutants were in an increasing trend in the past five years. The characteristics of air pollution and the specific influence factors were analyzed to find the cause of poor air quality in the Heping District in the past five years. And the preliminary governance prevention measures were proposed to solve the problem of pollution by strengthening environmental regulation, restricting environmental access, multi-sectoral joint law enforcement, and establishing a long-term mechanism, etc.
