摘要: 1976-1978年我们对华北平原与长江下游平原的泥炭资源进行了考察与勘探,这个地区泥炭的分布比较普遍,泥炭地的类型、特征以及形成时代等,在我国东部平原地区具有一定的代表性。此外,通过泥炭研究第四纪,特别是全新世,已经引起人们的重视。所以本区的泥炭地的研究具有一定的理论与实践意义。

Abstract: Huabai plain and the lower reachers of Yangtze River plain in China are regions of which buried peatlands are widely distributed.The cover layers of peatland are chiefly within five meters.In this region,there exist three ypes of peatland,subdivided into seven patterns.Ⅰ.River Valley Type Peatland 1.Washland pattern peatland 2.Paleochannel pattern peatland Ⅱ.Lake Basin Type Peatland 3.Lagoon pattern peatland 4.Barrier lake pattern peatland Ⅲ.Cleuch Type Peatland 5.Head pattern peatland 6.Cleuch pattern peatland 7.Fan’s edge in mouth of cleuch patternp eatland.The peatlands in this region were chiefly formed in Mesoholocene,secondly were formed in eoholocene,and only a small part was formed in Euholocene.The ancient castline in high sea level period in the earlier stage of Mesoholocene could be used as boundary of peatland distribution.In peatland to the eastof this boundary line,there were two buried peat layers,the lower peat layer was formed Chiefly in Euholocene,the upper peat layer was formed chiefly in the later stage of Mesoholocene to Neoholocene.The peatlands to the west of this boundary line were formed chiefly in the earlier stage of Mesoholocene.
