The invention relates to a forest resource monitoring method and device based on a laser radar and a storage medium. The method comprises the steps: carrying out feature variable extraction according to laser point cloud data, and obtaining sample plot feature variable data and global feature variable data; according to the sample plot feature variable data and the ground survey sample plot, establishing a laser radar accumulation estimation model; analyzing the global feature variable data through forest resource management data to obtain a tree species (group) set; inputting the tree species (group) set into the laser radar forest stand volume estimation model for calculation to obtain global forest stand volume estimation information, and deducing the global forest stand volume estimation information to obtain a tree measurement factor set; and updating the forest stock and tree measurement factor information to forest resource management vector data, and managing forest resources by a development informat
