探讨了广西禄峰山林场16年生4种密度湿地松Pinus elliottii人工林生态系统的碳积累、分配及与林分密度的关系.结果表明:4种密度湿地松人工林生态系统碳库的空间分布序列均为土壤层＞植被层＞死地被物层,碳库总量范围为264.834～323.978 t*hm-2,平均为291.663 t*hm-2,随着林分密度的增大而增加.植被层的碳贮量范围为96.614～110.717 t*hm-2,占碳库总量的35.40%,各组分碳贮量排列均为树干＞树根＞树枝＞树叶,碳贮量的地上/地下之比为7.185～7.922,随着密度的增大而下降.随着林分密度的增加,死地被物层的碳贮量由5.746 t*hm-2-增加至9.181 t*hm-2,占2.17%～2.83%.土壤层(0～60 cm)的碳贮量平均为18...

Carbon accumulation and distribution were studied in 16-year-old experimental slash pine plantations with four kinds of different densities at Lufeng Forest Farm in Guangxi Autonomous Region.The results indicated that the spatial distribution sequence of carbon storage ranked as soil layer>vegetation stratum>litter floor,the total carbon storage ranged from 264.834 t·hm~ ( -2) to 323.978 t·hm~ ( -2) ,with an average value of 291.663 t·hm~ ( -2) ,and increased along with enlarging of density in 4 kinds of different densities of slash pine pla...
