中文摘要:通过分析2001—2012年上海市PM_(10)浓度(由API(Air Pollution Index)转化得到)的变化规律,构建了上海市PM_(10)浓度的遥感反演模型。结果表明:1)上海市PM_(10)浓度存在季节性变化,应分别建立遥感反演模型。2)分析MODIS气溶胶光学厚度(Aerosol Optical Depth,AOD)产品与PM_(10)浓度之间的相关性发现,AOD须经过垂直和湿度订正才可与PM_(10)建立较好的关系。3)结合垂直和湿度订正分别建立的上海市PM_(10)浓度春夏秋冬四季的遥感反演模型均通过了拟合度检验,其中春季模型采用指数函数、夏季和秋季模型采用二次多项式函数、冬季采用幂函数、全年采用二次多项式函数,利用此四季模型反演上海市PM_(10)浓度具有较高的可信度。

外文摘要:By analyzing the variation rule of PM_(10) concentration( concluded by a conversion of API( Air Pollution Index))in Shanghai from 2001 to 2012,this paper establishes the remote sensing inversion model to measure PM_(10) concentration in Shanghai. As indicated by the results,the follow ing conclusions can be arrived at: 1) There is a seasonal variation for PM_(10) concentration in Shanghai,thus remote sensing inversion models in four seasons should be established,respectively. 2) By probing into the correlation betw een M ODIS AOD( Aerosol Optical Depth)products and PM_(10) concentration,this paper arrives at the conclusion that only by going through aerosol vertical distribution and relative humidity error correction can AOD establish a preferable correlation w ith PM_(10) concentration. 3) Based on the aerosol vertical distribution and relative humidity error correction,all the four-season remote sensing inversion models established to measure the PM_(10) concentration in Shanghai have passed the test of fitting degree. Among them,the spring model uses the exponential function,the summer and autumn models apply the quadratic polynomial function,the w inter model adopts the pow er function,and the yearly model uses the quadratic polynomial function. It is comparatively highly reliable to invert Shanghai PM_(10) concentration using the fourseason remote sensing inversion models.
