摘要：以云杉属4个树种(白扦、青扦、云杉、丽江云杉)为对象,通过查阅文献资料收集了这4个树种主要分布省份(山西省、甘肃省、四川省、云南省)的树木生长量调查信息,并汇总了单木生长过程及胸径处树皮厚度数据,分析各树种树高、胸径、材积的平均生长量和连年生长量变化规律,同时对3个生长指标的总生长量以及树皮厚度进行模型拟合与精度检验。结果表明:1)云杉属4个树种在不同分布区单木生长过程符合一般林木生长规律,并且0-40 a的树高、胸径连年生长量增长速率较快,而材积连年生长量在40 a后增长速率较快,除白扦外其他树种在不同分布区的总生长量无显著性差异;2)各树种单木生长方程和树皮厚度模型拟合精度较高,树高与胸径拟合最优模型多为二次曲线模型,而材积拟合最优模型多为理查德模型,树皮厚度拟合最优模型为双对数模型和二元一次线性模型。研究可为云杉属的人工林经营与管理提供理论参考。
In this paper,four species of Picea(P.meyeri,P.wilsonii,P.asperata,and P.likiangensis)were taken as the research objects.By consulting documents,the investigation information of tree growth in the four tree species in the main distribution provinces(Shanxi,Gansu,Sichuan,and Yunnan)were collected,the data of single tree growth process and bark thickness at DBH were summarized.Meanwhile,the average growth of the tree height,DBH and volume as well as the regular pattern of annual growth were analyzed for each tree species.Moreover,mathematical empirical equations were fitted about the total growth of above three growth indexes and bark thickness,and their accuracies was tested.The results showed that 1)the single tree growth process of four Picea species in different distribution areas was accorded with the generally regular pattern of forest growth,and the annual growth rate of tree height and DBH from 0 to 40 years was faster,while the annual growth rate of volume was faster after 40 years.There was no significant difference in the total growth of other species in different provinces except for P.meyeri.2)The model fitting accuracies of growth and bark thickness of single tree were all relatively high for each tree species.The best fitting models of tree height and DBH were mostly quadratic curve models,while the best fitting models of volume were mostly Richard model types,and the best fitting models of bark thickness were both Bouble logarithmic model and Binary linear model.This study can provide a theoretical reference for the construction and management of Picea plantation.
