<p dir="ltr">We extracted the NDVI data of sample points based on UAV-acquired multispectral imagery, and simultaneously measured the ground LAI data of these sample points. After establishing a relationship model between NDVI and LAI using Random Forest, we generated LAI images from the park's NDVI imagery and analyzed the LAI characteristics and their influencing factors in the park.</p>
