磁化率、碳酸钙含量和有机碳含量可用作良好的气候指标，主要是反映了降水量的变化。祁连山东段北麓哈溪剖面研究表明，９５６０ａＢ．Ｐ．时本区已进入全新世。大暖期是对温度而言，与气候适宜期是不同的概念，二者在时间上也不一定是同时的。本区的气候适宜期为６．８～３．６ｋａＢ．Ｐ．，气候最宜期为５．０～３．６ｋａＢ．Ｐ．，与其它记录有不同之处。在７．８～７．２ｋａＢ．Ｐ．和１．５～０．８ｋａＢ．Ｐ．间出现了“冷湿”的气候组合，这与传统的气候组合不同，但后一阶段的“冷湿”是有大量证据的。９．０～８．７ｋａＢ．Ｐ．间是全新世最干旱的时段，堆积了砂黄土。 Magnetic susceptibility, calcium carbonate content and organic carbon content can be used as good climatic indicators, mainly reflecting changes in precipitation. The northern section of the Haxi section of the eastern section of the Qilian Mountains shows that 9560aB. P. This area has entered the Holocene. The Great Warm-up period is a concept of temperature which is different from the climate-suitable period, and the two may not necessarily be simultaneous in time. The climate in this area is suitable for 6.8 ~ 3.6kaB. P. , The most suitable climate is 5.0 ~ 3.6kaB. P. , And other records are different. In 7.8 ~ 7.2kaB. P. And 1.5 ~ 0.8kaB. P. There is a “cold and wet” climate combination, which is different from the traditional climate combination, but the latter stage of “cold and wet” there is a lot of evidence. 9.0 ~ 8.7kaB. P. Between the driest period of the Holocene, sand loess piled up.
