| 摘 要： | 为了减少红松二次生长影响，正确设计和科学实施红松营林措施，文章运用响应函数分析，研究了人工林红松二次生长造成的过渡带宽度对气候变化的响应。结果表明，气候变化可以说明过渡带宽度径向变异的43．9％。过渡带宽度主要对温度变化响应显著，当年2、3月份最高地温升高有利于过渡带木材的形成，但是当年4月和7月最低地温升高会抑制过渡带木材的形成。另外，前一年9月和10月日照时间对过渡带木材的形成有显著的滞后影响。

| Abstract: | In order to reduce secondly growth of Pinus koraiensis,plan and manage plantations reasonably,the responses of transi- tional wood width to climate change were studied by the response function analysis.The results showed that 43.9%of variations in transitional wood width were explained by the climate change.The responses of transitional wood width to temperatures were signif- icant.The highest soil temperatures in February and March could accelerate evidently the increment in transitional wood,but ex- treme... |
