Vegetation index was constructed based on the fingerprint spectrum of vegetation to complete the spatial distribution and area statistics of target vegetation in the designated area, and to provide quantitative vegetation canopy density data for scientific research and production inagriculture, forestry and grass, ecology and other fields.
By using vegetation factors such as NDVI and LAI, quantifying the consistency of vegetation canopy status at different spatial scales, and using characteristic spectra of vegetation in different health states to quantitatively assess ve-getation growth,which can prov-ide data support for irrigation, fe-rtilization, plant protection, yield evaluation and other work.
According to the characteristic spectrum of pests and diseases and crop growth, the severity of pests and diseases and the spatial distribution of crop health status can be quantitatively judged, which can provide data support for disaster assessment, crop yield estimation, agricultural and forestry plant protection, etc.
According to the difference of canopy spectrum and leaf surface texture, a crop lodging evaluation model was constructed, and the lodging degree and spatial distribution of different lodging degrees were quantitatively described by combining with the statistical data of ground sampling points, which provided data support for disaster assessment and crop yield estimation.
