为了建立滇西北云南松测树因子与各器官的生物量模型,在宁蒗县翠玉和红桥乡设置云南松样地,在样地内选取云南松样木伐倒进行生物量器官称重调查,查数截取的树干圆盘年轮,建立了云南松单木各器官生物量与测树因子回归模型,分析了云南松的连年生长量。结果表明,利用胸径和各器官生物量建立的滇西北云南松生物量模型具有很好的精度。
為瞭建立滇西北雲南鬆測樹因子與各器官的生物量模型,在寧蒗縣翠玉和紅橋鄉設置雲南鬆樣地,在樣地內選取雲南鬆樣木伐倒進行生物量器官稱重調查,查數截取的樹榦圓盤年輪,建立瞭雲南鬆單木各器官生物量與測樹因子迴歸模型,分析瞭雲南鬆的連年生長量。結果錶明,利用胸徑和各器官生物量建立的滇西北雲南鬆生物量模型具有很好的精度。

for establishing tree biomass models of Pinus Yunnanensis Faranch in northwest Yunnan province, eight sample plots were set at Cuiyu and Hongqiao township in Ninglang county. 12 trees of Pinus Yunnanensis Faranch were cut and parts of them were weighted. Tree biomass models of Pinus Yunnanensis Faranch were established based on survey data and the accuracy of models are Precise.
