Study on correlation between crop optical vegetation index and radar parameters and its influencing factors based on plot unit
This study investigates the correlation between optical vegetation indices (NDVI, EVI, and DVI) in the Xixiu Modern Efficient Vegetable Agricultural Demonstration Park using Sentinel-1A radar and Sentinel-2A optical imagery.Results show that VH back-scattering coefficients exhibit the most significa...

| description | This study investigates the correlation between optical vegetation indices (NDVI, EVI, and DVI) in the Xixiu Modern Efficient Vegetable Agricultural Demonstration Park using Sentinel-1A radar and Sentinel-2A optical imagery.Results show that VH back-scattering coefficients exhibit the most significant correlation with optical vegetation indices across time periods, while VV, RVI, and CR show weaker or inconsistent correlations. Landscape shape index (LSI) and patch size significantly influence these relationships, with larger LSI or patch sizes enhancing the correlation between VH, VV, RVI, and NDVI/DVI. |
