对闽南地区麻竹人工林地上部分生物量模型及现存生物量结构进行了研究。结果表明:以模型m=a·(D2H)b对麻竹地上部分总生物量和秆生物量进行估计较为可靠,而对枝、叶生物量的估计需引进枝下高因子h及模型m=a·Db·(H-h)C或m=a·Db·[(H-h)/h]C。闽南地区麻竹人工林地上部分平均现存生物量为39.518t·hm-2,按年龄分配为:3年生生物量最高,占59.17%,其次为2年生、4年生、5年生;按器官分配为:秆生物量最高,占62.81%,其次为枝、叶。地上部分总生物量与秆生物量随竹秆高度增加而递减,枝、叶生物量自6~8m区分段分别向秆基及秆梢递减
The biomass model and existing biomass structure of the aboveground part of Artemisia matsutake plantation in southern Fujian were studied. The results showed that it was more reliable to estimate the aboveground biomass and stalk biomass of A. mongolicum with m = a · (D2H) b. However, the estimation of biomass of stalk and leaf needed to introduce the high branchlet h and the model m = a · Db · (H-h) C or m = a · Db · [(H-h) / h] C The average biomass of the aboveground part of the bamboo plantation in southern Fujian Province was 39.518 t · hm-2. According to the age distribution, the three-year biomass was the highest (59.17%), followed by two years, four years and five years Organ distribution was as follows: stalk biomass was the highest, accounting for 62.81%, followed by branches and leaves. The aboveground biomass and stalk biomass decreased with the increase of bamboo height. The biomass of branches and leaves decreased from 6m to 8m to the stalk and stem
