森林可持续管理对"四库"安全的作用机制与实证分析OA

[Objective]This study aims to quantitatively analyze the mechanism and impact pathways of forest sustainable management on"Four-Repository"security,providing decision-making references for improving forest resource management system construction.[Method]Based on panel data from 31 provinces in China from 2011 to 2022,this study comprehensively employed the entropy method,two-stage least squares method,and mediation effect model to construct an evaluation index system for forest"Four-Repository"security and analyze the impact mechanism of forest sustainable management on"Four-Repository"security.[Result]1)Forest sustainable management has a significantly positive impact on"Four-Repository"security,with the greatest impact on forest resource utilization sustainability,and relatively smaller impacts on forest resource protection investment and forest system restoration intervention.2)Forest sustainable management promotes"Four-Repository"security through two pathways:enhancing forestry green development resilience and strengthening forest ecosystem service value.The impact on forest resource utilization sustainability is mainly exerted through the pathway of enhancing the ecological service value,while the impact on forest resource protection investment and system restoration intervention is significantly operated through both pathways of enhancing forestry green development resilience and strengthening forest ecosystem service value.3)The impact of forest sustainable management on"Four-Repository"security shows significant differences across different functional zones and economic development level regions.Forest resource utilization sustainability plays the most prominent role in key ecological functional zones,and different economic development level regions exhibit evolutionary characteristics from resource dependence to efficiency improvement and then to ecological service orientation.[Conclusion]To deepen the synergistic development of forest sustainable management and"Four-Repository"security,it is necessary to strengthen policy orientation for sustainable utilization of forest resources,construct differentiated regional forest resource management systems,establish synergistic enhancement mechanisms for forest resilience and ecological services,improve institutional systems for forest"Four-Repository"security assurance,and enhance the comprehensive support capacity of forest resources for"Four-Repository"security.
