摘　　要：热岛效应正成为城市气候变化的主要因素之一。作为城市必要的设施,污水处理厂因其产生的温室气体排放和处理运行过程中消耗大量的能源和资源对全球性气候变化产生影响,而其对区域性气候变化的影响却鲜有研究。利用热红外遥感图像反演地表温度是研究和监测热岛效应常用的手段之一。通过利用LandsatTM/ETM+图像对哈尔滨市九座污水处理厂2000-2013年的地表温度进行反演,并利用热岛强度来评价污水处理厂的热岛效应。研究发现,十三年间污水处理厂热岛强度增加了53%。通过主成分分析和多元线性回归分析发现,污水处理厂热岛强度与处理水量、城市表面温度等呈正相关性,而与排放标准、污水处理厂距离松花江中心的距离、建设施工状态和主体处理工艺呈负相关性。Heat island effect has been a significant factor contributing local climate change at the city level.As a necessary infrastructure in urban system,Wastewater Treatment Plants(WWTPs)have been recognized as a contributor to global climate change due to its greenhouse gas emissions and huge energy and resource consumption.But their impacts on local climate change have been hardly studied.Landsat TM/ETM+images,infrared remote sensing imagery,were used to study heat island effect of nine WWTPs in Harbin by retrieving surface temperature during 2000-2013.Results showed that heat island intensity of nine WWTPs increase by 53%during the time.Principle Factor Analysis and multiple linear regressions showed that heat island intensity of WWTPs are positively correlated with treatment volumes,urban surface temperature and negatively correlated with discharge standards,construction condition and treatment process.
