| 摘 要： | 以井冈山自然保护区天然林(常绿阔叶林)和人工林(杉木林、厚朴林和毛竹林)中的灌木为研究对象,对其碳密度和重要值进行了对比分析。结果表明,常绿阔叶林碳密度最大,为0.153 kg/m3,厚朴林碳密度最小,为0.027 kg/m3,前者是后者的5.6倍;4种森林类型中灌木碳密度排序为:常绿阔叶林>人工杉木林>毛竹林>厚朴林;天然林中灌木高度、基径和生长状况优于人工林。

| Abstract: | The shrubs in natural forest and man-made woods of Jinggangshan nature reserve were selected as research objects for comparing and analyzing their carbon densities and importance values.the selected natural forest was evergreen broad-leaved forest and the selected man-made woods were fir forest,Magnoliae officinalis woods and mao bamboo woods.The results indicated that the carbon density of evergreen broad-leaved forest was highest,being 0.153 kg/m3 and that of M.officinalis woods was lowest,being 0.027 kg/m3,the former was 5.6 times of the latter.The carbon density sequence of shrubs of 4 forest types was evergreen broad-leaved forest > man-made woods were fir woods > mao bamboo woods > M.officinalis woods;the height,base diameter and growth status of shrubs of natural forest was superior to that of man-made woods. |
