Figure 4. Relationships between measured rice leaf area index (m²/m²) and dry aboveground biomass (g/m²) at different rice growth stages with VIs. (a) Before heading LAI estimation using EVI2-BPNN regression; (b) after heading LAI estimation using NDVI-SVM regression; (c) all-growth stage AGB estimation using daily cumulative NDVI and based on the quadratic polynomial fit function; (d) all-growth stage AGB estimation using 10-day composite data and based on the cumulative NDVI quadratic polynomial fit function. The black dash lines are the 45° lines, and the red solid lines are the linear regression trend lines.
