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。
The stratified cutting method was used to determine the biomass of various organs in aerial and underground parts of sightseeing woods. According to the correlation analysis, the correlation between biomass and DBH and tree height of each part of sightseeing wood was found out, The mathematical models that overestimated the biomass of various organs were obtained. The mathematical models W = a Db and W = a Db Hc were obtained by comparing the biomass estimation models. Among them, W = a Db Hc is more ideal and can be used for estimating the sightseeing wood biomass in sightseeing wood distribution area.
