| 摘 要： | 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。

| Abstract: | The construction of aboveground biomass and biomass model of Dendrocalamus latiflorus plantation in South Fujian are studied in this paper.The results are showed as follows: (1)The aboveground biomass and the biomass of culm of D.latiflorus may reliably be calculated by the model, m=a·(D2H)b,but the biomass of its culm and leaf may not.In order to calculate it, it is necessary to introduce the factor, clear height,and the models, m=a·Db(H-h)c and m=a·Db·[(H-h)/h]c.(2)The total aboveground biomass of D.latiflorus plantation in South Fujian is 39.518 t·hm-2 .The biomass of 3-year-old is the highest,accounting for 59.17 percent of the total, followed by that of 2-,4-and 5-year old successively.The biomass of culm is the highest in terms of organ, accounting for 62.81 percent of the fotal, followed by that of branch and leaf successively.The total aboveground biomass and the biomass of culm gradually decrease along the height, and that of branch and leaf gradually decreases from the section of 6～8 m to the top and to the bottom. |
