摘要: 运用逐步回归分析方法,对辽河源地区油松生长与气象因子之间的关系进行分析,结果表明:影响油松胸径生长量的主导气象因子是年蒸发量、年日照时数和年降雨量;影响油松树高生长量的主导气象因子是年日照时数、年蒸发量和年降雨量。由此可知,对辽河源地区油松生长量影响较大的气象因子是年蒸发量、年日照时数和年降雨量。

关键词: 油松, 气象因子, 相关分析, 辽河源地区

Abstract: In this study,the stepwise regression method is used to explore the relationship between tree growth and climatic factors of Pinustabulaeformis in the source areas of the Liaohe River.Results indicated that the dominant factors notably influencing the radial growth of Pinustabulaeformis are annual evaporation,annual sunshine duration and yearly precipitation; the major factors obviously influencing the elongation growth of Pinustabulaeformis stem are annual evaporation,annual sunshine duration and yearly precipitation.Thus,we can conclude that the climatic factors having a noticeable effect on the growth of Pinustabulaeformis are annual evaporation,annual sunshine duration and yearly precipitation.

Key words: Pinustabulaeformis, climatic factor, correlation analysis, the source areas of the Liaohe River
