| 摘 要： | 在分析树木生长对气候要素响应的基础上,利用采自天山中段南坡夫斯坦沟的雪岭云杉树轮宽度年表,重建了巴仑台地区1360~2004A.D.当年7月至次年6月的降水量序列,方差解释量达53%(调整自由度后为52%)。交叉检验结果表明重建方程稳定可信。过去645a以来,巴仑台地区的降水量变化存在12个偏少阶段和12个偏多阶段。巴仑台地区降水量重建序列存在10.7~11、6.7和2.1a的显著准周期及16.5~17.2和2.4~6.6a的较显著准周期,并且在1496A.D.前后发生了降水量由少向多的突变。

| Abstract: | Dendroclimatology is one of the important methods for examining the past global climate changes and the tree-ring data were used widely as an important archive in paleoclimatic research because of its precise dating,annual resolution,and high correlation with instrumental meteorological data.Based on tree-ring chronologies,long-timescale climate variations have been reconstructed on both regional and hemispheric spatial scales.The study area,the Baluntai region is located on the southern slope of the mid-Ti... |
