Utilizing the current status data of the three issues of land use in the North Mountains of Lin'an Changbei in 2010, 2015, and 2020， according to the subjective land use intention of the behavior subject, it is the basis for the division of "Production-living-ecological" land use.The evolution characteristics of "Production-living-ecological" land use in Changbei Mountain Area in recent ten years were calculatedaccording to the transfer matrix of land use,land use change map, single land use dynamic degree, land use structure information entropy and other methods, The results show that the land use is in the stage of slow development, but the information entropy value of the land use structure is increasing year by year, especially after 2015, the negative entropy flow of human activity interference input has increased significantly, the equilibrium level of the land use structure is low, and the internal structure of the land use system in Changbei Mountain Area is developing in a disordered direction. The reason is directly related to the expansion of local industrial and mining land and the blind pursuit of production development: the increase of industrial and mining production land will make the internal structure of the land use system develop disorderly, and the increase of forest and grass ecological land can make the system more orderly. The analysis results can provide basic research support for scientifically adjusting the land use relationship of "Production-living-ecological" in Changbei Mountain Area and exploring the road of sustainable and coordinated development of "Production-living-ecological" benign interaction.
