Natural resource grade evaluation method and device, terminal equipment and storage medium

The invention relates to the technical field of land grade evaluation, and discloses a natural resource grade evaluation method and device, terminal equipment and a storage medium, and the method comprises the steps: obtaining a natural resource type in a to-be-evaluated region; acquiring sample data and influence factors of various natural resource types; wherein the influence factors comprise property right properties, protection grades and resource properties of natural resources; establishing a multiple linear regression model according to the influence factors; according to the sample data, training a multiple linear regression model to obtain a natural resource regression model corresponding to various natural resource types; dividing the natural resources in the to-be-evaluated region into grids, and calculating the unit area asset value of each grid according to the natural resource regression model; and determining the evaluation grades of the natural resources according to the unit area asset value,
