中文摘要：
通过对红原泥炭沉积剖面Pb，Zn，Fe，Mn，Cu，Co，Ni，Ti，V，Al等10种元素和灰分的测试，发现多数元素在该剖面的变化与灰分变化较为一致，但Cu，Pb和Zn元素的变化在剖面300cm以上出现较大异常：这3种元素的变化与其他元素变化呈相反的规律，而且Pb和Zn两种元素的含量较之剖面下部出现数量级的增大。通过对比，发现元素含量的异常与位于剖面上风区的甘青地区新石器时代晚期一青铜时代文化在发生时间上较为吻合，认为这可能是人类活动环境效应的记录。用600—300cm段的元素变化作为背景值，用与Pb，Zn元素相关较好的4种元素分别计算出二者变化的自然背景值，从而分离出了人类活动强度信息与自然环境背景值，分离结果与著名的青海柳湾墓地出土人口规模对比较好。
英文摘要：
We report the preliminary comparison of the element abnormity （Cu, Pb, Zn） in the peat profile from Eastern Tibetan Plateau with the ancient culture sequence from Gansu-Qinghai in the upper drifting area of the sample site. Peat cores were drilled every 50cm by specific peat sampler from the Hongyuan peatland in Eastern Tibetan Plateau. The sample site is located in the high terrace of Baihe River, 2km southwest away from Hongyuan County （32°46′42″N, 102°31′0″E）, where the sediments were rarely influenced by the fluvial sediments. The element concentration （Pb, Zn, Fe, Mn, Cu, Co, Ni, Ti, V, Al） and ash content proxy are measured at every 8cm and lcm respectively in peat cores. Variations of all the ten elements are consistent well with each other from 600cm to 300cm; while from 300cm to lcm variations of most elements are still consistent with that of the ash content, except Cu, Pb, and Zn which changed abnormally. Variations of these three elements are counter to those of the other elements from 300cm to lcm; and the amplitudes of Pb and those from 600cm to 300cm by about one order of magnitude. 5500aB. P. when the Neolithic and Bronze Age Cultures are Zn concentration in this stage are much larger than The age of the element abnormity started from about well developed in Qinghai-Gansu area at where the upper drifting area of the sample site is located. To decipher the reason of the element abnormity we have compared the element abnormity with the sequence of ancient cultures from the late Neolithic to Bronze Age in the area of Qinghai Province and Gansu Province and found out that these two phenomena＇ are closely correlated to each other, which may indicate that the peat sediment in Hongyuan preserved the information of ancient human activity. Since the variations of the ten elements are consistent well with each other from 600cm to 300cm, it is supposed that the elements of this stage are of the natural background value that is not influenced by human activity. Four elements （Ti,
