Abstract [Objective] To comprehensively analyze the currnt situation of forestry，environment and economic development in Pingliang region，and toassess the coordination and changing trendsamong them.[Methods]Taking Pingliang MunicipalityinLongdongastheresearcharea，a19-index evaluationsystemof the "forestry-environment - economy" ternary system was constructed.The entropy method and the coupling coordination degree model were adopted to analyze the evolution characteristicsofthe ternary systemfrom 2011to 2O22.[Results]Thedevelopmentof the ternary subsystem was unbalanced.Forestryshowedafluctuating decline（G1～O.3O），the environment fluctuated sharply（G2 drops from O.73 toO.41），and the economyrecovered steadilyin thelater stage（G3 rises fromO.40to0.58）. The overall degree of system coupling cordination was at an intermediate level （D=0.61-O.7O），dropped to barely coordinated （D=0.435 4）from 2016 to 2018，reached good coordinated （D=0.7113）in 2021，andthen declined. [Conclusion]Theinsuficient stabilityofforestryis themainconstraintonthe imbalanceof theternarysystem.Itcan provide a scientific reference for the coordinated development of regional ecology and economy.
