According to the standard methods and principles of dendrochronology,we developed a tree-ring chronology of Fokienia hodginsii in Changting,Fujian and investigated the relationships between tree growth and monthly average temperature and monthly total precipitation during the period from 1956 and to 2013.It is found that tree growth is positively correlated with current autumn(from September to October)temperature and previous spring-summer(from April to August)precipitation.Results of moving correlation analysis with a 25 a window reveal that despite of the instability of the relationships between tree growth and temperature and precipitation,the relationships are both evident during the period from 1970s to 1990s.This finding suggests that climate variability may be more limited to tree growth during this epoch.In addition,we also find that the radial growth of Fokienia hodginsii cannot be promoted highly simply because of the increase of temperature or precipitation.The notable promotion of growth occurs when both temperature and precipitation rise.%基于树木年代学的研究理论与方法,建立了福建长汀地区福建柏(Fokienia hodginsii)的树轮宽度的标准化年表,并探索了其径向生长与1956-2013年期间前年3月到当年11月的月均温、月降水量气候因子的响应特征.结果表明:福建柏的径向生长主要与当年秋季(9-10月)温度气温与前年春夏季(4-8月)降水显著正相关(P<0.05);25 a滑动相关分析发现两者相关显著的时段比较一致,均集中在1970s-1990s时段,说明该时段气候因子对树木生长的限制作用更为明显.响应面回归分析表明,仅气温温度或降水的改善,并不能显著促进福建柏的径向生长,只有当两者同时改善后,树木的生长才会加速.
