| Abstract: | In this paper,it was briefly narrated concept and characteristics of hyperspectral remote sensing technology,and the principle of using hyperspcral remote sensing to estimate forage aboveground biomass.Additional, it was looked back the application of vegetation index in pasture science fields.And it also narrated the characteristics of vegetation index NDVI(normalized difference vegetation index)and RVI(ratio vegetation index).Finally it was discussed the relationship between vegetation indices and grassla... |
