摘  要：
采用密度调控对贵州台江县12年生马尾松人工林碳储量进行研究。结果表明,密度调控提高了马尾松人工林乔木层、林下植被和凋落物层碳的累积,高密度(H)(1 800株·hm~(-2))、中密度(M)(1 566株·hm~(-2))和低密度(L)(1 350株·hm~(-2))及CK(未间伐:2 016株·hm~(-2))密度下马尾松人工林各组分碳储量乔木层>土壤层>林下植被层>凋落物层。乔木层碳储量分别高出CK2.58、5.69t·hm~(-2)和1.38t·hm~(-2);土壤层分别高出CK3.50、4.95t·hm~(-2)和-13.43t·hm~(-2);林下植被层分别高于CK1.88、2.59t·hm~(-2)和4.14t·hm~(-2),凋落物层分别高于CK0.14、0.27t·hm~(-2)和0.36t·hm~(-2),林下植被和凋落物层碳储量较CK达显著差异(p<0.05);H和M密度下生态系统总碳储量分别较CK提高8.1t·hm~(-2)和13.49t·hm~(-2),L密度低于CK7.54t·hm~(-2),马尾松人工林生态系统总碳储量以M密度调控最大,故马尾松中龄人工林林分经营过程中以M密度经营较好。

摘  要：
An investigation of the effects of density regulation on carbon deposits was conducted on a 12-year-old Pinus massoniana plantation located in Taijiang County of Guizhou Province.Besides the control(CK,without regulated,2 610plant·hm~(-2)),three densities were set up:high(H,1 800plant·hm~(-2)),medium(M,1 566plant·hm~(-2)),and low(L,1 350plant·hm~(-2)).The results showed that density regulation helped improving the carbon accumulation in the tree layer,understory vegetation and litter layer.The amounts of carbon storage was in the order of tree layer>soil layer>litter layer> undergrowth layer under all densities.The carbon storages in tree layers with high,medium and low densities were 2.58,5.69,and 1.38t·hm~(-2) higher than that of the control;in soil layer,3.50,4.95,and 13.43t·hm~(-2) higher,in litter layer,1.88,2.59,and 4.14t·hm~(-2) higher;and in undergrowth layer,0.14,0.27,and 0.36t·hm~(-2)higher.The carbon storages of understory vegetation and undergrowth layer were significantly different compared with CK(p<0.05).The total carbon storages of the ecosystem with H and M densities were8.1t·hm~(-2) and 13.49t·hm~(-2) higher than the CK,and with L density,7.54t·hm~(-2) less than the CK.It was concluded that the total carbon storage of P.massoniana plantation ecosystem with M density was the highest,indicating that M density should be adopted in the management of middle-age P.massoniana plantation.
