摘要: 对福建德化葛坑国有林场1996年种植的秃杉Taiwania flousiana人工林植被碳库和氮库分配格局进行调查。结果表明,秃杉人工林各器官碳含量在442.86~488.72 g·kg-1之间,而各器官氮含量在2.26~8.93 g·kg-1之间。20年生秃杉人工林单株碳库和氮库分别为96.10 kg和0.679 kg。各器官碳库大小顺序为树干(64.56 kg) >树根(16.11 kg) > 树叶(8.18 kg) > 树枝(7.25 kg)。各器官中氮库大小顺序为树干(0.379 kg) > 树叶(0.157 kg) > 树根(0.085 kg) > 树枝(0.058 kg)。乔木层的碳库和氮库主要集中在树干,分别占67.18%和55.82%。20年生秃杉人工林林分植被碳储量和氮储量分别为84.29 t·hm-2和0.60 t·hm-2。

Abstract: The distribution patterns of vegetation carbon and nitrogen pool of Taiwania flousiana plantations planted in 1996 at the Dehua Gekeng National Forest Farm were studied. The results showed that carbon contents of different organs were ranged from 442.86 to 488.72 g穔g-1, and nitrogen contents of different organs were ranged from 2.26 to 8.93 g穔g-1. The carbon and nitrogen pool per tree was 96.10 and 0.679 kg in the 20 a T. flousiana plantation, respectively. The carbon pool of different organs followed an order as trunk (64.56 kg) >root (16.11 kg) >leaf (8.18 kg) >branch (7.25 kg), while the nitrogen pool followed as trunk (0.379 kg) >leaf (0.157 kg) >root (0.085 kg) >branch (0.058 kg). The vegetation carbon and nitrogen pool of tree layer mainly distributed in trunk, which occupied 67.18% and 55.82%, respectively. The carbon and nitrogen storages of 20 a T. flousiana plantations were 84.29 t穐m-2 and 0.60 t穐m-2, respectively.
