巴罗ＡＢ－６７钻孔岩芯的４８个样品被进行了２５个项目的粒度分析和４４个项目的地球化学分析。本文对这些数据进行了Ｑ型因子分析，并得到了４个主因子。研究表明，这４个因子分别代表了沉积环境的四项指标，它们分别为沉积速率、降水、海平面和温度。从岩芯顶部５个样品与巴罗气象台观测记录确定了古温度和古降水的转换函数，从２１０Ｐｂ测年和几个环境事件确定了沉积速率的转换函数。从沉积相的变化识别出了海平面因子。重建的温度和降水的曲线表明，１６、１７世纪巴罗地区的环境比现在更为寒冷、干旱。１８、１９世纪温度升高而降水变幅很大，２０世纪的温度和降水波动都很剧烈，重建的温度曲线在岩芯的微体古生物变化组合上得到了很好的印证。
Forty-eight samples of Barrow’s AB-67 bore core were subjected to particle size analysis of 25 projects and geochemical analyzes of 44 projects. This paper conducted a Q-factor analysis of these data, and got four main factors. The results show that these four factors represent the four indicators of sedimentary environment, respectively, sedimentation rate, precipitation, sea level and temperature. The conversion function of palaeoprotectant and paleo-precipitation was determined from observations of five samples at the top of the core and Barro meteorological station. The deposition rate conversion function was determined from the 210Pb dating and several environmental events. The sea level factor was identified from changes in sedimentary facies. The reconstructed temperature and precipitation curves show that the Barro region was cooler and more arid in the 16th and 17th centuries. During the 18th and 19th centuries, the precipitation increased greatly due to the temperature increase. The temperature and precipitation in the 20th century fluctuated violently. The reconstructed temperature curve was well confirmed in the microphysophytic assemblage of cores.
