2003~2020年广西国有维都林场森林资源数量与质量动态分析

Dynamic Analysis on Forest Resource Quantity and Quality in Guangxi State-Owned Weidu Forest Farm from 2003 to 2020

摘要: 为全面掌握林场森林资源数量与质量变化情况，促进林场森林资源高质量发展，采用2003-2020年广西国有维都林场森林资源规划设计调查报告数据，对林业用地、森林面积、森林蓄积、森林覆盖率、森林生长量、森林消耗量等49项指标分析森林资源数量动态变化；并采用层次分析法在森林起源、森林结构、森林产能、森林健康、森林价值等方面综合评价森林质量。结果表明，2003年到2020年维都林场森林资源在数量上有较大的增加，森林质量有所上升，从及格等级上升到中等等级，当前制约森林质量提升关键评价指标是单位面积蓄积量严重偏低、平均径级偏小。针对存在问题提出了精准提升森林质量的意见建议。

Abstract: In order to known the changes of forest resource quantity and quality in Guangxi state-owned Weidu 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, forest growth, per unit area stock volume, forest consumption were statistically analyzed, and the forest resource quality was evaluated according to its forest origin, structure, productivity, health and value. The results are as follows: the forest resource quantity was increased and forest quality was promoted from 2003 to 2020. The rank of the forest resource quality valuation was increased from pass to medium. The key indicators restricting forest quality were that per unit area stock volume and DBH (diameter-breast-height) were very small. Some suggestions for accurate promoting the forest quality in Weidu Forest Farm were proposed.
