| 摘 要： | 运用树木年轮气候学方法，研究了河北木兰围场油松的生长与气候要素之间的关系.结果表明：油松生长对环境变化十分敏感，以早材最为敏感.5、6月气温与油松生长存在显著的负相关关系；6月的降水和相对湿度对油松早材的生长有促进作用， 上年9月到翌年9月的降水对油松生长有更强的促进作用；12月到翌年3月的相对湿度对油松晚材生长的促进作用较干旱和全轮显著；油松的生长与大尺度气候波动存在一定的相关性.1951—2006年间，围场地区增温明显.随气温的升高，油松生长对温度和降水的敏感性下降，且有向相反方向转变的趋势.百年尺度上5—6月平均气温的重建值与观测值差异较大，说明当地油松的宽度生长对气候因子变化的敏感性波动较大. |

| Abstract: | Dendroclimatic methods were used to investigate the relationships between the growth of Chinese pine (Pinus tabulaeformis Carr.) and the climatic parameters in Mulan-Weichang of Hebei Province. The results showed that Chinese pine presented high sensitivity to climatic changes, and its earlywood width showed the highest sensitivity. There was a significant negative correlation between the tree-ring width chronology of Chinese pine and the air temperature in May-June. The precipitation and relative humidity in June had strong positive effects on the growth of earlywood, the precipitation from September to next September had significant positive effects on Chinese pine growth, and the relative humidity in winter more strongly affected the growth of latewood than of earlywood. There was a definite correlation between the tree-ring width chronology of Chinese pine and the large scale climate fluctuation. From 1951 to 2006, the increase of air temperature in study area was significant, and the sensitivity of Chinese pine to the variations of local temperature and precipitation decreased, presenting an inverse transforming trend with increasing temperature. Greater differences were observed between the reconstructed and observed data of mean temperature in May-June in a century scale, suggesting that the tree-ring growth of Chinese pine in study area had a greater fluctuation of sensitivity to the variation of climatic factors. |
