摘  要:
对巨尾桉立木和林分叶面积开展研究,结果表明,巨尾桉立木叶面积与树高、胸径、枝下高、冠长存在极显著的正相关,且以胸径的拟合效果最好。建立了巨尾桉立木和林分叶面积估测优化模型,估测结果表明,9年生巨尾桉人工林单株的平均叶面积为(14.96±3.85)m2,林分的平均叶面积指数为2.40±0.72。所建模型可用于同类林分叶面积指数的估算。

摘  要:
The leaf area of tree and stand in 9-year-E.grandis ×E.urophylla were studied,and the results showed that the leaf area of tree of E.urophylla×E.grandis had remarkable positive correlation with tree height,DBH,clear length and crown length,and even more DBH.The optimum models of estimating tree and stand leaf area were established.Average individual leaf area and average stand LAI of eucalypt plantation were(14.96±3.85) m2 and 2.40±0.72 respectively by the models.Both models could be used in estimating leaf area index of similar plantations.
