中文摘要：

利用贺兰山同时存在高山气象站和山下气象站的条件,在高山气象站旁采集油松树轮样本,建立3种树轮年表,并选用标准年表分别与高山气象站和山下的阿左旗气象站的月降水量和月均温进行相关分析,探究利用山下气象站数据代替山上气候是否可行.结果表明,在贺兰山地区,用山下气象站数据代替高山气候,能较准确地反映树轮与月均温的响应显著的月份;而在反映树轮与月降水的响应关系时,则与真实情况有所差异.因此在树轮—气候的研究中,可以用山下气象站的数据代替山上的月均温,而不能代替月降水来进行相关分析.

英文摘要：

An alpine meteorological station (Helan mountain station)and a submontane meteorological station (Azuoqi station)are present in Helan mountains.This work will study whether data from the submontane meteorological station could replace data from the alpine meteorological station.Tree core samples of Pinus tabulaeformis were taken near Helan mountain station and three types of tree-ring chronologies were developed.Standard chronology was used to study correlation between tree-ring and two climatic parameters (mean monthly temperature and total monthly precipitation of Helan mountain station and Azuoqi station).It was found that correlation between chronology and mean monthly temperature of the two stations were similar, while correlation between chronology and total monthly precipitation of the two stations were discrepant. Therefore in tree ring-climate studies,mean monthly temperature data of submontane stations can replace the alpine stations,while total monthly precipitation data cannot.
