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.
