应用地球化学元素、地球化学淋溶系数及环境温度指标，研究了北极阿拉斯加巴罗热融湖Ｉｋｒｏａｖｉｋ钻孔岩芯ＡＢ－３２连续的高分辨环境记录。结合２１０Ｐｂ测年数据，指出巴罗地区气候、环境变化的历史状况是：１６００～１７３５年为寒冷、干燥时期；１７５０～１８３０年，气候变暖、变湿；１８３０年出现明显的地球化学转折界限，１８３０～１９９４年，气候较湿润温暖。１９６９～１９７０年前后，巴罗地区有一变冷阶段。ＡＢ－３２钻孔岩芯１８３０年左右表现的古地球化学特征与现代Ｉｋｒｏａｖｉｋ湖泊环境地球化学特征相吻合，并且和Ｅｌｓｏｎ泻湖ＡＢ－６７沉积岩芯反映的气候环境变化基本一致。
Using the geochemical elements, the geochemical leaching coefficient and the environmental temperature index, we studied the AB-32 continuous high-resolution environmental record of the Ikroavik borehole in the Barrow thermal lake in Alaska. Based on the 210Pb dating data, it is pointed out that the history of climate and environment change in Barrow region is: cold and dry period from 1600 to 1735; warming and wetting from 1750 to 1830; obvious geochemical turning point in 1830 From 1830 to 1994, the climate is more humid and warm. Around 1969-1970 there was a cooling phase in the Barrow area. The paleogeochemical characteristics of the AB-32 bore core around 1830 coincide with the environmental geochemical characteristics of the modern Ikroavik lake and are basically consistent with the climate and environment changes reflected by the AB-67 sedimentary core of the Elson Lagoon.
