三江平原是我国招泽炙中分布区之一。其中泥炭沼泽面积约242km².泥炭中的植物残休是沼泽的重要组成成分,又是泥炭分类和利用的依据。本文论述了该区泥炭的分布、泥炭植物残体类型及特征,同时还探讨了泥炭植物残体与沼泽形成的关系。

The Sanjiang Plain region situated Jn the northeastern end of China is one of the concentrated distribution areas of mire in the country.This region has 11192 km of marsh,of which peat moor is 242km².Peat is a special product of mire.Plant residues are important components in peat.Plant residues provide the scientific basis for peat classification and utilization.Therefore, the study on plant residues has both production practice value and theoretical significane. The paper discusses peat distribution and emphasizes the main types and characteristics of plant residuesas,as well as the relationship between plant residues and peat.The plant composition and vegetation types of mires are closely related to plant residues.
