摘要: 植物残体是沼泽植物死亡后,在过湿的嫌气环境条件下未完全分解的植物遗体,如根、根状茎、茎、叶、果实、种子、孢子和花粉等。东北是我国沼泽主要分布地区之一,沼泽面积达3万3千多平方公里。其中泥炭沼泽面积较大,是我国泥炭贮量丰富地区。植物残体是泥炭的主要组成部分,也是沼泽地的特殊产物。目前,国内外学者对泥炭分类,经常采用植物残体为分类指标之一。因此,植物残体既是泥炭的分类基础,又是泥炭利用的重要依据。所以研究泥炭中植物残体对泥炭的成因、类型、泥炭的理化性质、评定泥炭的利用以及对古植物、古地理、古气候的研究方面均有重要意义。

Abstract: The Northeast Region is one of concentrical distribution area of peat lands in China.In this region there are rich peat reserves constructed by various plant residues.Those residues have become basis of peat classification and utilization. The paper introduced the concept of plant residue,its signification and study way,and then proposed a classification system for plant residue.In additions9 the authors also made preliminary approach to types,characteristics, component and micro-structure of plant residue in peat in the Northeast Region.
