本文介绍了前苏联Grichuk教授及其合作者提出的古气候定量重建方法——Grichuk法,并运用该方法重建了山西张村晚上新世的温度参数,反映当时气候(年均温8.7～18.3℃,最冷月均温-3.0～9.5℃)远比今天(年均温8.8℃,最冷月均温-6.8℃)更温暖。同时,对同一套孢粉数据,采用不同方法得到的结果数据对比显示运用Grichuk法与共存分析法估算的古温度参数范围相近,但Grichuk法估算的古温度参数范围要比共存分析法的结果更宽些,其差别产生的原因可能与二者操作方法相异及参考的最近现存亲缘类群分布范围不同有关。
This paper introduces the Güluk method, an ancient paleoclimate quantitative reconstruction method proposed by Professor Grichuk and its collaborators in the former Soviet Union, and uses this method to reconstruct the temperature parameters of the late Pliocene in Zhangcun, Shanxi Province, reflecting the climate (annual average temperature 8.7 ~ 18.3 ℃ , The coldest month average temperature -3.0 ~ 9.5 ℃) is far warmer than today (annual average temperature 8.8 ℃, the coldest month average temperature -6.8 ℃). In the meantime, the comparison of the data obtained by different methods for the same sporopollen data shows that the range of palaeo-temperature parameters estimated by Grichuk method and coexistence analysis method are similar, but the range of palaeo-temperature parameters estimated by Grichuk method is more than that of coexistence method The reason for this discrepancy may be related to the different scope of the distribution of the recently existing relatives of kinship with the two methods of operation and the reference.
