In this study，the applications of broad-band vegetation index，normalized differential
vegetation index (NDVI) and green-red vegetation index (GRVI) to the quantity and quality
of grassland vegetation were discussed. Leaf area index (LAI) provides a measure of the
amount of vegetation. The chlorophyll concentration of leaves is often used to describe the
quality of vegetation，which is usually related to the nutrient content of vegetation. In the
PROSAIL model，a simulated spectr
