我国东部沿海地区,位于北纬18°12′—42°间欧亚大陆的东岸,面向太平洋,受海洋影响,是泥炭比较丰富的地区。本区的泥炭大多是全新世12000年来形成的,如今多数已被泥砂掩埋,属于埋藏泥炭。 本区毗邻海洋,泥炭的生成与分布同海洋有关。由于海洋性气候降水较多,湿度较大,对发育沼泽、堆积泥炭是较有利的。但我们认为本区泥炭比较丰富的主要原因,是由于海洋水体对陆地水的水力影响。而它们在空间与时间上的分布特征,则是海面在全新世有过较大幅度的升降,引起沿海地区海进、海退造成的。 本区埋藏泥炭的上覆盖层不厚,一般1—2米,容易开采。可制做各种腐植酸肥料,促进农业生产发展。此外,泥炭对研究第四纪具有十分重要的地位。因此,研究本区泥炭有着重要的经济意义与理论意义。
The eastern coast of China is located on the east coast of Eurasia between latitudes 18o 12’-42o north latitude and facing the Pacific Ocean and the sea. It is a region rich in peat. Most of the peat in this area was formed during the Holocene 12000 years ago, and most of the peat now has been buried by muddy sand and belongs to the buried peat. The area adjacent to the ocean, the formation and distribution of peat with the ocean. Due to the more precipitation and high humidity in the maritime climate, peat accumulation is more favorable for swamp development. However, we think the main reason for peat abundance in this area is due to the hydraulic impact of marine water on terrestrial water. Their spatial and temporal distribution is characterized by the significant sea level rise and fall during the Holocene, which caused the coastal areas to enter sea and retreat. Overburden covered peat in this area is not thick, usually 1-2 meters, easy to exploit. Can make all kinds of humic acid fertilizer, and promote the development of agricultural production. In addition, peat plays a very important role in the study of Quaternary. Therefore, peat research in this area has important economic and theoretical significance.
