The natural grassland production monitoring and estimation in the north of Xinjiang using remote sensing

In this paper, the data of spectral observations and the grass yield of natural grassland in the north of Xinjiang from 1991 to 1994 are used for analyzing the spectral vegetation index characteristics, studying the relation between the ground spectrum and satellite remote sensing data and establishing the grass yield monitoring model and the remote sensing monitoring and estimating model of natural grassland to the north of Xinjiang.
