利用巨尾桉(EUCALYP GRANDIS×UROPHYLLA)实测数据,采用数学模型模拟的手段,研究、分析树皮体积率和树皮干重率的估计方法。结果表明,用胸径估计树皮体积率和树皮干重率的效果与用树干带皮材积估计树皮体积率和树皮干重率的效果相近,树皮体积率的估计精度优于树皮干重率的估计精度。
Based on the measured data of EUCALYP GRANDIS × UROPHYLLA, the method of mathematical model simulation was used to study and analyze the estimation methods of bark volume fraction and bark dry weight. The results show that the estimation of the bark volume fraction and the bark dry weight rate by the DBH is similar to the estimation of the bark volume fraction and the bark dry weight fraction by the trunk bark skin volume. The estimated accuracy of the bark volume fraction is better than that of the bark Estimated accuracy of dry weight.
