Addressing the issues of insufficient consideration for non-market ecosystem services and unclear defini-tion of compensation control thresholds in forest ecosystem compensation,in this paper a regional ecological com-pensation mechanism oriented toward securing forest ecosystem service functions was proposed.Based on emergy analysis and integrated with multidisciplinary methods,a quantitative evaluation framework for forest ecosystem service functions was established.The M-K and Pettitt methods were jointly applied to the interannual sequence of functional benefits to identify abrupt changes and determine the compensation control threshold.A coupled human-nature emergy system was constructed to trace ecological and economic flows within and beyond the system,com-pensation standards(i.e.,the unit emergy value of forest resources)was defined,and the value compensation re-lationship between humans and forest systems was quantified with the constraint of functional benefit thresholds.This study provided a new perspective for forest ecological compensation research.The proposed theoretical frame-work and methodology were applied to Luoyang City in Henan Province.Results showed that the total emergy bene-fits of forest ecosystem functions exhibited a steady upward trend from 2010 to 2021,with a cumulative increase of 0.37%.The year 2016 was identified as the mutation point,with a compensation control threshold of 5.11E+22 sej.The years 2010-2015,during which the functional benefits were below the threshold,required compensation.During this period,the total compensation value showed a fluctuating decline,decreasing from 37.71 million yuan in 2010 to 12.64 million yuan in 2015.The compensation value was primarily driven by the magnitude of functional benefit reduction below the threshold,which was closely linked to the abundance of key ecological elements within the forest system.Therefore,continuously enhancing forest protection and sustainable management was essential to realize the goal of harmonious coexistence between humans and nature.
