| 摘 要： | 采用冬季采样，现场分层的方法，系统地研究了三江平原河床-河漫滩型泥炭地和谷底洼地型泥炭地微量营养元素和有益元素的垂直分布特征。结果表明，微量营养元素Cu、Zn、Fe、Mn、B和有益元素Ni、Sr、Ti、V、Co均有在G层急剧积累的趋势，Fe、Mn、B、Zn、Ti、Sr质量分数在Ase层明显高于泥炭层，某些微量元素间具有显著的相关性。

| Abstract: | Using the methods of sampling in winter and the dividing soil layers in soil profiles, the characteristics of nutrient trace elements and helpful trace elements concentration vertical distribution in peat sediments of river bed-flood land and valley depression land in Sanjiang Plain were systematically studied. The results showed that the content of nutrient trace elements Cu, Zn, Fe, Mn, B and helpful trace elements Ni, Sr, Ti, V, Co was accumulated sharply in G layer, the content of Fe, Mn, B, Zn, Ti, Sr in Ase layer was obviously higher than that in other peat layers, |
