摘　　要：为摸清福建酸竹生物量积累与分配特征,测定了1~4年生福建酸竹的秆、枝、叶生物量,分析了立竹地上构件生物积累与分配特征及其相对生长关系。结果表明,不同年龄福建酸竹构件含水率、生物量及其分配比例与相对生长关系差异明显。随立竹年龄增加,秆、枝、叶含水率明显下降,而其生物量及总生物量则显著增加;秆生物分配比例及异速生长指数总体下降,而枝、叶生物量分配比例及其异速生长指数总体升高。综合分析表明,福建酸竹丰产林经营宜多留养2年生、3年生立竹,适量留养4年生立竹。In order to better understand the characteristics of aboveground modular biomass accumulation and allocation in Acidoasa longiligula,the paper measures the culm,branch and leaf biomass of 1-4 a bamboos,and analyzes the characteristics of their aboveground biomass accumulation,allocation and their allometric growth.The results show that aboveground modular water content,biomass accumulation and allocation as well as the allometric growth of A.longiligula at different ages differs obviously.With the bamboo age increasing,the water content of culm,branch and leaf decreases markedly,while their biomass and the total aboveground biomass increases significantly.The proportion of culm biomass to the total biomass and its allometric growth index decrease,while those for branch and leaf increase obviously.The comprehensive analysis indicates that 2 a and 3 a bamboos should be more kept,with appropriate number of 4 a bamboo,for the management of high-yield bamboo forest.
