摘要
应用分层切割法，测定了观光木地上及地下部分各器官的生物量，据相关分析，找出观光木各器官生物量与胸径、树高之间的相关关系，建立用观光木胸径和树高估测各器官生物量的数学模型，通过生物量估测模型的比较，得到了精度较高的数学模型 Ｗ＝ ａ Ｄｂ 和 Ｗ＝ ａ Ｄｂ Ｈｃ 。其中以 Ｗ＝ ａ Ｄｂ Ｈｃ 更为理想，可用于观光木分布区内观光木生物量的估测。
Based on the surveys of biomass of Tsoongiodenron odorum, the relations between various organs and BDH or height were obtained by using the method of correlation analysis. The forecastion models for DBH, height and various organs biomass of Tsoongiodenron odorum have been established, which can be used for forecasting the biomass in the distribution area of Tsoongiodenron odorum.
