| 摘 要： | 以陕西黄土高原沟壑区小叶杨天然和人工林为对象,在获取大量的林分生长信息的基础上,采用修改的Richards方程、指数方程和山本和藏式,建立了小叶杨个体、群体优势高、材积、胸径等的生长预测模型,编制了本区二元材积表,并导算出一元材积方程.

| Abstract: | By using the modified Richards model and exponent function, the growth prediction functions of dominant tree height, volume and diameter at breast height (DBH) for Populus simonii in the gully rolling region of Shaanxi Loess Plateau have been developed based on the adequate growth data, the two factor volume table was constructed, and one factor volume prediction function was deduced from the models. |
