摘要

•LCC was estimated based on the UAV-based image analysis.•The response stability of vegetation index and LCC was analyzed under different coverage.•Different variable screening methods were used to optimize the spectral parameters.•The spatial distribution map of maize LCC was constructed to provide potentials for fertilization application.
