The urban heat island effect has become one of the important factors that affect the local climate change in the development of urbanization. As part of the city the necessary infrastructure,the impacts of urban sewage treatment plants on global climate change havereceived widespread concern and research,however,the influence of the local climate change is rarely studied. This paper first attempts to use the Landsat satellite remote sensing image to study the urban heat island effect of city sewage treatment plant in Suzhou city during the period of 1995-2013,and its influencing factors are analyzed. It was found that the heat island intensity of 11 urban sewage treatment plants increased by 48% in the whole 18 years. From the perspective of the time dimension,in the sewage treatment plant construction or upgrading phase,the heat island intensity is high. According to the regression analysis,it is found that the average temperature of the urban surface,the construction and construction of sewage treatment plants and the main treatment process and WHII has a significant positive correlation.
