【摘要】 运用相关函数及单年分析等树木年轮气候学方法,研究三峡库区上游马尾松径向生长与气候变化的关系,结果表明,马尾松的生长对环境变化比较敏感,不同海拔马尾松对降雨量和气温的响应不同,海拔600m处马尾松生长与5,6月份的降雨和湿润指数显著相关,而海拔900m处马尾松与环境的关系相对复杂,除受当年5,6月份温度影响外,还受上年11月份湿润指数的影响,说明同一地区不同海拔梯度的马尾松对气候的响应具有不同特征。最后用多元回归模型回归了马尾松径向生长与气候因子之间的关系。更多还原

【Abstract】 The relationship of Pinus mussoniana radial growth in upriver,Three-gorge reservoir area in China with climate change was assessed by dendrochronological techniques including correlation functions and single-years analysis.The results showed that Pinus mussoniana growth in high and low elevations had a significantly different response to temperature and precipitation.In low elevation,Pinus mussoniana growth was significant correlated to the mean precipitation and the humid indies of May and June,but in high elevation,it had a more complicated relationship to the environment.Besides the mean temperature of May and June,the humid index of last November significantly correlated with the Pinus mussoniana tree-ring width.Therefore,it was not the same relationship of the same tree species with different environmental gradients.Finally the correlation model in different elevations of tree ring width index and climatic factors was simulated by multi-factor regression.更多还原
