Taking the forest resources of land M as an example for application research, remote sensing data are collected, and the research is carried out in terms of the dynamic changes of different levels of forest resource information extraction. The results can be obtained that the forests in the middle and eastern parts of Land M have a low degree of depression, with an average diameter at breast height (DBH) of less than 18 cm and a stock volume of less than 100 m3/ha, while in the western part, the degree of depression and the average diameter at breast height (DBH) are higher, and the density of the forest stands in each region is concentrated at 500-1000 plants/ha. The overall forest cover of the land showed an increasing trend from 2016 to 2020.
