摘　　要：应用响应函数分析方法研究东北地区人工林樟子松生长轮宽度对气候变化的响应,结果表明:前1年4月至当年9月的气候变化可以解释生长轮宽度径向变异的44.1%。温度是影响樟子松生长轮宽度径向变异最主要的气候因素,其中,当年6月平均气温对其影响最大,回归系数达到-0.350。The response of annual ring width of Pinus sylvestris var. mongolica plantation grown in the northeast China to the climate change including temperature, precipitation and sunshine duration was studied by response fimction analysis. The results showed that the change of climate factors from April of the former year to September of the current year might account for about 44. 1% of the variation in the annual ring width. The most important climate factor to influence upon the annual ring width was temperature of the current year. Especially, the response of annual ring width to the temperature in June of the current year was the most significant, whose coefficient was -0. 350.
