摘　　要：根据采自山东蒙山地区两组幼龄黑松树木年轮样本，研制出单点和区域树轮宽度年表，分析了蒙山黑松树轮宽度年表的统计参数和径向生长的气候限制因子，并尝试重建相关密切的气候因子，探讨蒙山黑松径向生长与大范围气候变化的关联。研究结果表明，（1）蒙山黑松树轮宽度年表的统计参数都比较高，说明蒙山黑松树轮宽窄变化包含有较多的气候环境变化信息。（2）蒙山黑松径向生长变化与当年4-9月降水量呈显著正相关。同时，当年5-7月异常高温也对蒙山黑松径向生长变化产生显著抑制。通过黑松树轮宽度年表对4-9月降水量的模拟重建结果表明蒙山黑松具有较大树轮气候研究潜力。（3）蒙山黑松树轮宽度生长与太平洋大范围气候波动存在显著关联。According to two sets of samples of young Pinus thunbergii trees obtained from two individual sites in Mengshan Mountain, single-point and regional tree-ring width chronologies were developed.Based on statistical parameter from the chronologies, we analyzed relationships between tree radial growth and climate limiting factors, tried to reconstruct the related climate factors, and further explored the relationships between the radial growth and large-scale climate change of Pacific Ocean.The results showed that： （1） the statistical parameters of tree-ring width chronologies were high that indicated the pine trees from Mengshan had high sensitivity to the climate change. （2） the radial growth of Pinus thunbergii was positively correlated with precipitation from April to September, while high temperatures from May to July had great negative influence on the radial growth.Based on the results of above climate response analyses, climate research potential of the Pinus thunbergii from Mengshan had been showed. （3） The tree-ring width growth had remarkable correlations with the large scale climate change of Pacific Ocean.
