江西省安福县北华山林场碳储量计算及策略研究
摘要
<span>森林资源可持续经营管理是林业可持续发展的核心。清楚了解林场的碳储量和碳密度有利于指导林场现代生态林业建设，利于林场的可持续经营。本文以江西省北华山林场</span><span lang="EN-ZA">2016</span><span>年森林经营方案数据为基础，运用生物量</span><span lang="EN-ZA">-</span><span>蓄积量关系模型和平均生物量法，测算了北华山林场森林的碳储量与碳密度。结果表明：北华山林场森林总碳储量为</span><span> <span lang="EN-ZA">200848.28t</span></span><span>，平均碳密度为</span><span lang="EN-ZA">32.87t/hm2</span><span>。乔木林生物量碳储量是北华山林场森林生物量碳储量的主体，碳储量为</span><span lang="EN-ZA">200808.45t</span><span>，占森林总碳储量的</span><span lang="EN-ZA">99.98%</span><span>，单位面积平均碳密度为</span><span lang="EN-ZA">32.88t/hm2</span><span>。单位面积固碳能力毛竹林</span><span lang="EN-ZA">&gt;</span><span>乔木林</span><span lang="EN-ZA">&gt;</span><span>经济林。毛竹林碳密度最大，单位面积平均碳密度为</span><span lang="EN-ZA">40.95 t/hm2</span><span>。乔木林中，马尾松固碳能力最优，碳密度为</span><span lang="EN-ZA">43.12t/hm2</span><span>。</span>
