泥炭沼泽的形成和演化

泥炭沼泽的形成可分为水域泥炭沼泽化和陆地泥炭沼泽化两大类。泥炭沼泽可分为低位泥炭沼泽、中位泥炭沼泽和高位泥炭沼泽。由泥炭沼泽发育的内在聚集规律所决定,泥炭沼泽形成后,可由低位泥炭沼泽经中位泥炭沼泽发展至高位泥炭沼泽。研究泥炭沼泽的形成和演化,对剖析泥炭层的生成以及成分和性质,具有实际意义;对分析成泥炭时的古气候和环境乃至构造活动的稳定性,也有一定的意义。

THE FORMATION AND EVOLUTION OF PEAT SWAMPS

The formation of peat swamps can be divided into two major categories,i. e. waterlogged peatification and terrestrial. There are three types of peat swamps: raised swamps, intermediate swamps and low-level swamps. Depending on the inherent accumulating relations, a formed peat swamp may evolves form a low-level one into a intermediate or a raised one. The study of the formation and evoluation of a peat swamp is significant not only for analyses of the formation, the compesition and the nature of a peat bed, but olso for analyses of characteristics of palaeoclimate and environments even the stability of geological structures during peat-forming period.
