摘　　要：运用地理信息系统的研究方法,针对桂东南地区的地理位置和自然环境,采用经典暗像元法,并借助IDL语言调用6S模型生成相应查找表的方法,对研究区及周边区域2009年MODIS高分辨率(1KM×1KM)影像进行气溶胶光学厚度反演.反演结果与AERONET(aerosol robotic network)国际气溶胶监测网站公布的Bac_Giang、MuKdahan和Hongkong_poly站点气溶胶厚度观测值进行精度验证.最后得出桂东南地区2005、2007、2009、2011年的气溶胶时空分布特征反演情况,并分析结果.By using geographic information system, aiming at the southeast of Guangxi geographical location and natural environment, using the classic dark pixel, the corresponding lookup table method based on IDL language call 6S model were generated to inverse high resolution MODIS （1KM x 1KM） image of aerosol optical thickness in 2009 in the study area and the surrounding area. The inversion results were compared with aerosol thickness observations of Bac Giang, MuKdaban and Hongkong..poly sites published on the AERONET （aerosol robotic network） international aerosol monitoring website to verify the accuracy. Finally, the inversion of spatial and temporal distribution characteristics of aerosol in southeast of Guangxi in 2005, 2007, 2009, 2011 were obtained and analyzed.
