摘　　要：为全面掌握高峰林场森林资源动态变化情况,促进林场森林资源高质量可持续发展,基于2003—2020年高峰林场森林资源规划设计调查报告数据,对林场林业用地、森林面积、森林蓄积、森林覆盖率、林地利用率、单位面积蓄积量、森林生长量、森林消耗量等40多项指标进行统计分析。采用层次分析法从森林起源、森林结构、森林产能、森林健康、森林价值等5方面37项指标对森林质量进行评价,结果表明:2003—2020年高峰林场森林质量从及格等级上升到中等等级。筛选出制约森林质量提升关键评价指标7项:公益林地占比偏低、特用林缺失、杉树面积比重偏低、松类面积比重偏低、单位面积年均生长量偏低、平均径级偏小、混交林占比偏低。针对制约森林质量提升关键评价指标,提出了精准提升森林质量的建议。To gain a comprehensive understanding of the dynamic changes in forest resources at Gaofeng Forest Farm and to foster high-quality,sustainable development,over 40 indicators based on data from the 2003—2020 Gaofeng Forest Farm forest resource planning and design survey report were analyzed,including forestry land use,forest area,forest volume,forest coverage rate,land utilization rate,per-unit volume,forest growth,and forest consumption.Using the Analytic Hierarchy Process(AHP),forest resource quality based on five criteria:forest origin,forest structure,forest productivity,forest health,and forest value were evaluated.The results indicated that from 2003 to 2020,the forest quality at Gaofeng Forest Farm improved from a passing grade to a moderate level.Seven key indicators limiting further improvement in forest quality were identified:the low proportion of public welfare forest land,the absence of special-purpose forests,the low proportion of Cunninghamia lanceolata area,the low proportion of pine species area,the low average annual growth per unit area,the small average diameter class,and the low proportion of mixed forests.
