人工林大青杨木材生长轮宽度对气候因子的响应分析

摘要

A study was performed to discuss the responses of growth ring width of wood from Populus ussuriensis plantations to climatic factors in order to realize the directed breeding of high quality plantations by the response function method. Results showed that the 21 percent of radial variation of growth ring width of P. ussuriensis wood was caused by climatic factors. The main climatic factor influencing the radial variation of growth ring width was relative humidity, especially relative humidity in January, and the regression coefficient was -0.367.%为了实现人工林大青杨优质木材的定向培育,以人工林大青杨木材为研究对象,运用响应函数分析方法研究了人工林大青杨木材生长轮宽度对气候因子的响应.结果表明:气候因子对人工林大青杨木材生长轮宽度径向变异的影响可以达到21％；相对温度是影响大青杨木材生长轮宽度径向变异最主要的气候因子,其中1月的相对湿度影响最大,回归系数为-0.367.
