:With the development of computer technology and aerial and space technology, remote sensing moni-toring has been become a simple, fast and high effective monitoring method, and extensively being used on geo-logical prospecting, environmental monitoring, weather forcast and agriculture. It achieve considerable success.Because of hyperspectral resolving power, extra-multi-band and large information capacity, hyperspectral re-mote sensing is a powerful means used to observe the earth and the key of moden remote sensing, and has awidespread application prospects in agriculture. Hyperspectral data (especially differential hyperspectrum) arecorrelate to leaf area index (LAI), leaf chlorophyll density (CH. D) and other biochemical contents such asprotein and so on. It is introduced on the difficult problems, present and future of hyperspectral remote sensingin agriculture in this article.
