【摘要】 森林资源二类调查作为林业管理的核心环节，对生态安全建设与资源可持续利用意义重大。该文基于北京市八达岭林场2019年森林资源二类调查数据，系统梳理了该林场森林资源的数量、质量及结构特征。并结合以往调查数据，分析了森林覆盖率、蓄积量等关键指标的动态变化规律。研究发现八达岭林场呈现森林覆盖率相对较高、蓄积量相对较低、林分结构有待优化等特点。通过与全国及北京市平均水平的森林资源进行对比分析，探讨了影响森林资源高质量发展的关键因素，以期为国有林场森林资源精准管理与生态治理提供理论与实践参考。更多还原

【Abstract】 As the core link of forestry management, forest resource class II inventory is of great significance to ecological security construction and sustainable utilization of resources. Based on the class II inventory data of forest resources in Beijing Badaling Forest Farm in 2019, this paper systematically combed the quantity, quality and structural characteristics of forest resources in the forest farm. Combined with the previous survey data, the dynamic changes of key indicators such as forest coverage and volume were analyzed. The study find that Badaling Forest Farm has the characteristics of relatively high forest coverage, relatively low volume, and stand structure to be optimized. Through the comparative analysis with the national and Beijing average levels, the key factors affecting the development of forest resources are discussed, in order to provide theoretical and practical reference for the precise management and ecological management of forest resources in state-owned forest farms.更多还原
