Many spectrum data including flue-cured tobacco, corn and rice and so on were obtained from Linshu County, by open-air Analytical Spectral Device through measurement on the spot. Spectrum of flue-cured tobacco was analyzed on ecological characteristics. A good performance was obtained to identify three kinds of vegetations by calculating the area of red absorption peak. The study provides a good foundation for tobacco monitoring by land sat remote sensing images.
