摘　　要：研究西伯利亚落叶松生长量与气候因子之间的相互关系,对预测气候变化对森林系统的影响具有重要意义。文中利用相关性分析与多元回归分析的方法分析了西伯利亚落叶松生长量对气候因子变化的响应特征。结果表明:落叶松材积生长量与降水量呈极显著正相关(p<0.01),相关系数达到0.998,说明降水是影响落叶松生长的主要限制因子;落叶松材积生长量与年平均气温、年平均最高气温呈显著负相关(p<0.05),说明温度的升高不利于西伯利亚落叶松的生长;而落叶松材积生长量与年平均最低温度呈负相关,但相关性不明显;而降水和温度的共同作用对西伯利亚落叶松生长的影响更显著。Research on the relationship between the Siberian larch growth and climatic factors is important for understanding the climate change effects on forest systems. In this research, correlation analysis and multiple re- gression analysis method were used to analyze the response of Siberian larch growth factor to climate change char- acteristics. The results showed that： larch timber volume growth and precipitation was significantly positively cor- related （ p 〈 0.01 ） , the correlation coefficient was 0. 998, indicating that the impact of precipitation was the main limiting factor for the growth of larch; larch timber volume growth and annual average temperature, annual the average maximum temperature were the significant negative correlations （ p 〈 0.05）. description of the tem- perature rise was not conducive to the growth of Siberian larch, and larch timber volume growth and average an- nual minimum temperature was negatively correlated, but the correlation was not obvious. Combined effects of precipitation and temperature more pronouncedly influenced the Siberian larch growth.
