英文摘要	Hyperspectral technology brings us not only the improvement of biochemical inversion precision, but also data redundant in some extent. This paper examines the relation of spectral resolution and the inversion precision with two field experiment data sets, LOPEX'93 and our field experiment on rice held in 2004. Two lands of inversion methods, statistical regression and vegetation indices, are employed on original reflectance and first derivative reflectance of a spectral resolutions levels, 2 nm, 5 nm, 10 nm, 20 nm and TM simulated bands. Results show that the inversion precision decreases When the spectral resolution becomes coarse. However, such change is not linear. The finer the resolution is, the less the change is. In our study, we find that a spectral resolution at 5 nm is enough for both water and chlorophyll inversion.
