摘 要 ：在冬季对福建省华安县竹园14属46种（含变种和栽培型）竹类植物叶的热值和灰分含量进行了研究。结果表明：竹类植物叶的灰分含量在8.05%～28.14%之间，平均为15.18%；干重热值在14957.3 ～19111.4 J/g之间，平均为17672.1 J/g；去灰分热值在19473.1～24646.2 J/g之间，平均为20845.6 J/g；竹类植物叶干重热值和灰分含量有显著的线性关系，相关方程为Y=－169.21X+20241（r=0.7370**，df=44），高灰分含量是竹叶干重热值相对较低的重要原因之一。

Abstract:The ash contents, gross caloric values and ash free caloric values in leaves of 46 bamboo taxa (including varieties and cultivars) of 14 genus in the Bamboo Garden of Hua‘an County, Fujian in winter were studied. The ash contents, gross caloric values and ash free caloric values in leaves of these bamboo taxa varied from 8.05% to 28.14%, from 14957.3J/g to 19111.4J/g and from 19473.1J/g to 24646.2J/g, respectively. Gross caloric values （Y） correlated remarkably with ash contents（X）, the regression equation being Y= -169.21X+20241(r=0.7370**, df=44). The high ash contents resulted in low caloric values in dry leaves of bamboos.
