Distribution and Implications of Major and Trace Elements in Peat Profiles of Yuanchi,Changbai Mountain

This article discussed the distribution of major and trace elements of peat in Yuanchi,Changbai Mountain.Four profiles were collected with Wardenaar peat sampler produced in Netherlands.Each sample was cut into 1～2 cm at the present.As far as the special physical conditions in Yuanchi are concerned,the content of major and trace elements(Na、K、Mg、Ca、 Al、Ti、Fe、Mn、Zn、Pb、Cu)were determined among different peat bogs.The elements distribution with depth in each peat profile was fully analyzed.Also we have analyzed the enrichment of different elements in peat profiles.Through the calculated M/Ti(M refers to Na、K、Mg、Ca、 Al、Ti、Fe、Mn、Zn、Pb、Cu) ratio,compared with ratio of M/Ti collected from literature,we concluded the differences among different peat bogs.The increasing content of Mn、Zn and Pb from bottom to top in peat profiles proves the increasing pollution of them in present environment,which has profound implications for environment.
