| 摘 要： | 本研究为克服优势木对比法在天山云杉的选优工作中的一些缺陷，采用双重逐步筛选回归的方法，建立了由三株优势木对比法所得候选树性状的优良度、均值、缩差、标准差和变异系数对标准地上的林分和候选材相应性状参数的估测方程。使优势木对比法和标准地法有机的结合起来．用前者的资料得到后者的信息．从而间接的估算出期望遗传增益。

| Abstract: | In order to overcome some defects of compare tree checking system in Tianshan Picea. this thesis has emploied double sifting regression atep by step to have established some regression equations which can be used to estimate superiority mean. standard deviate,standard deviation and variation coefficient of stand and candidate tree in sample plot. Combined with the three checking syste with sample plot checking system organically the three cheeking system can provide existing information about the sample plot and estimate the expect genetie gian. |
