东北地区泥炭微量元素的研究

On Trace Elements in Peat from Northeast China

研究了我国东北地区草本泥炭、泥炭藓泥炭和草本－木本泥炭中微量元素的储存量及其分布特点，并分析了泥炭形成的地域特点和泥炭的理化性质，从而提出了泥炭类型、物质组成和理化特性是影响泥炭中微量元素的主要因素．测试结果表明，泥炭中微量元素含量为陆相沉积泥炭小于海相沉积泥炭；泥炭藓泥炭低于草本泥炭和木本－草本泥炭．

Quantity of trace elements and their distribution in herbacious, Sphagnum, and herbaciouswooden peat from northeast China are studied.The areal properties of peat forming and the physical-chemical characteristics of peat are analysed. Thereby, the concept is put forward that substance composition and the physical-chemical properties of peat are the main influencing factor for trace elements in peat. The test results show that the content of trace elements in continental peat is larger than that in marine peat; Sphagnum peat contains less trace elements than herbacious peat and wooden-herbacious peat.
