Abstract: In order to monitor crop planting area and predict its production,HJ-1 satellite(No.1 Environment satellite union of A and B) remote sensing data were used to analyze the spectral reflection characteristics of flue-cured tobacco crop and other ground objects.Three vegetation indices,including normalized difference vegetation index(NDVI),difference vegetation index(DVI) and ratio vegetation index(RVI),were calculated and their discrimination of flue-cured tobacco from other ground objects was analyzed and compared.The method for recognition of flue-cured tobacco from remote sensing data was determined,and the planting information of flue-cured tobacco in Jingxi County,Guangxi was extracted with the developed method.The method precision was verified with GPS field sampling data,and the obtained total precision was 92.79% with Kappa coefficient of 0.8374.It suggested that remote sensing technology could be used to obtain tobacco planting information quickly and accurately.
