摘要
为全面掌握广西国有六万林场森林资源动态变化情况,促进林场森林资源高质量发展,基于2003~2020年六万林场森林资源规划设计调查报告数据,对林场各类土地面积、森林资源数量、森林资源质量40多项指标变化情况进行系统分析。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分析,结果表明,2003年到2020年六万林场森林质量从及格等级上升到中等等级。同时,筛选出制约森林质量提升关键评价指标8项:特用林缺失、用材林面积比重偏低、杉木类面积比重偏低、松类面积比重偏低、单位面积蓄积量偏低、单位面积年均生长量偏低、乔木林平均径级偏小、混交林林分比重偏低。针对制约森林质量提升关键评价指标,提出森林质量精准提升的5条建议。
In order to understand dynamic changes of forest resources in Guangxi state-owned Liuwan Forest Farm, to promote high-quality development of forest resources in the forest farm, using the data of forest resource investigation of the forest farm from 2003 to 2020, woodland, forest area, forest stock volume, forest covering rate, woodland using rate, forest growth, per unit area stock volume, forest consumption were statistically analyzed. The forest resource quality in Liuwan Forest Farm was evaluated in AHP (the Analytic Hierarchy Process) according to the forest origin, forest structure, forest productivity, forest health and forest value. From 2003 to 2020, the grades of the forest resource quality valuation in Liuwan Forest Farm from pass to medium. According to the analysis on the key indicators restricting forest quality, 5 important suggestions for accurately promoting the forest quality in Liuwan Forest Farm were proposed.
