| 摘 要： | 从影响林木生长的环境因子入手，采用数学方法，找出了影响各引种栽培区内１－６９／５５杨生长的主导气象因子和主导土壤因子。在此基础上，采用数量化方法编制了Ｉ－６９／５５杨立地指数得分表。根据大量的固定标准地和临时标准地资料，经综合分析，提出了１－６９／５５杨的适宜造林密度和各项丰产栽培技术措施。

| Abstract: | In this paper, by multivariate regression analysis,authors figured out the leading climateand soil factors affecting the growth of Populus clone 1-69/55. By means of quantitative theory I. Siteindex objective mark table of the clone was divised. Based on the data investigated from a great number of temporary sample plots and permanent plots,some intensive culture models for industrial useswere suggested. |
