以福建省德化葛坑国有林场1996年种植的秃杉人工林为研究对象,开展林分生物量和生产力研究。结果表明:20年生秃杉人工林单株平均生物量为202.56 kg,其中地上部分生物量、地下部分生物量分别为167.74、34.81 kg,分别占个体总生物量的82.81%、17.19%;各组分生物量大小排序为:干>根桩>叶>枝>粗根>细根>中根。秃杉林分总生物量达177.75 t·hm~(-2),其中乔木层的总生物量为176.23 t·hm~(-2),占林分总生物量的99.14%;凋落物的生物量含量比较小,只有1.52 t·hm~(-2),仅占林分总生物量的0.86%。20年生秃杉人工林的生产力为11.87 t·hm~(-2)·a~(-1),各器官生产力大小排序为:树干>树叶>树根>树枝。
Taking Taiwania flousiana plantation planted in 1996 as a research object in Gekeng National Forest Farm, Dehua, Fujian Province, the biomass and productivity of stands were studied. The results showed that the average biomass of the 20-year-old Taiwania flousiana plantation was 202.56 kg, of which the above-ground biomass and underground biomass were 167.74 and 34.81 kg, accounting for 82.81% and 17.19% of the total biomass respectively. The order of biomass was: stem> root pile> leaf> branch> root> fine root> root. The total biomass of Taiwania flousiana reached 177.75 t · hm -2, in which the total biomass of tree layer was 176.23 t · hm -2, accounting for 99.14% of the total biomass of stand. The biomass of litter Only 1.52 t · hm -2, accounting for only 0.86% of the total biomass of stand. The productivity of the 20-year-old Taiwania flousiana plantation was 11.87 t · hm -2 · a -1. The order of productivity of each organ was as follows: trunk> leaves> roots> branches.
