摘　　要：应用响应函数分析方法研究了东北地区人工林红松生长轮宽度对月平均气温等气候因素变化的响应,结果表明:前一年4月到当年9月的气候变化对人工林红松生长轮宽度径向变异可产生40.8%的影响;温度是影响红松生长轮宽度径向变异最主要的气候因素,其中,前一年9月平均地温的影响最大,回归系数达到0.441。A study was conducted to determine the variation of growth - ring width of planted Pinus koraiensis in northeast China in response to climate change, such as monthly mean temperature, by using the analytical method of response functions. Ahat about 40.8% radial variation of the growth ring width were resulted by climate change from April of the previous year to September of the same year. Temperature is a key factor affecting the radial variation of the growth ring width of Pinus koraiensis. The average ground temperature in September of the preceding year had the most significant effect on the variation in the growthring width, with a regression coefficient of 0.441.
