摘要
1 前言裸露泥炭是现代沼泽地里仍在积累的泥炭,表面无泥、沙掩盖。我国裸露泥炭资源丰富,其储量约占泥炭总储量的80%左右,而埋藏泥炭只有五分之一。多数分布在我国的东北地区兴安岭、长白山地、三江平原等湿润的寒温带、中温带泥炭区,是我国泥炭沼泽分布面积最广,裸露泥炭丰富的地区之一。在青藏高原和新疆也有较大面积的分布。泥炭是沼泽的特有产物,其中固相物质主要是由植物残体、腐植质以及矿物质组成的。植物残体指造炭植物遗体在嫌气条件下未被完全分解而残存于泥炭的部分,它主要包括植物的根、根状茎、茎、叶、果实、种子、孢子和花粉等。就造炭植物种属来说,可以称为苔草残体、镰刀藓残体、紫杉残体等等。因为沼泽是在某种特定环境下。
According to the taxonomic principle that classifies by the genetic ralations of the plant residue and their differences of form and on the basis of the dominant life patterns of the pear- forming plants,the main types of the plant residue in exposed peat in Northeast of China,the Qinghai-Xizang Plateau and Xin- jiang are now tentatively devided into 20 groups of 5 types. In order to make the best use of the peat resources,the dev- elopment and exploitation of these resources should be conducted rationally according to the principal characterics of each type of the plant residue. The exposed peat mean the peat which are accumulating in present marshland.There are rich exposed peat resources in our country.Its reserves make up 80 per cent of the total peat rese- rves(27 billion tons).Therefore.the study of the plant residue in exposed peat has both practical value for production and the- oretical significance for us to have a scientific understand and rational use of peat resources.
