In recent years, the implementation of the national policy of returning farmland to forestry has provided a vast space for maximizing the comprehensive benefits of large-scale slope farmlands in western Liaoning. Based on this, it is of great significance to analyze the distribution characteristics and features of natural vegetation in Lingyuan area, Liaoning Province. Combining with the ecological characteristics of each native species, it is of great significance to apply the conversion of cropland to forestland on slope farmland and improve the economic benefits per unit area.
