我国沿海地区,北起鸭绿江口,南止北仑河口,大致呈南北伸展,向东突出的狭长弯弧状,为我国泥炭地分布较广的地区之一。在我国沿海除台湾省以外的八个省份,178个县,约有泥炭地四千余处,面积约45万公顷,泥炭储量约占全国总储量的11%。如今,本区泥炭多为泥砂所掩埋属埋藏泥炭地。本区毗邻海洋,泥炭地的形成与海洋水体对陆地水的水力影响有关,因而表现在泥炭地的类型以及它们在空间和时间上呈有明显的分布特征。这对于研究第四纪,尤其是全新世以
China’s coastal areas, north of the Yalu River Estuary, the North End Beilun estuary, extending roughly north-south, prominent long curved arc, is one of the areas of peatland widely distributed. In the eight provinces and 178 counties except Taiwan Province along the coast of our country, there are about 4,000 peat fields covering an area of about 450,000 hectares and peat reserves accounting for about 11% of the country’s total reserves. Nowadays, most of the peat in this area is buried in muddy burial peatland. This area is adjacent to the sea. The formation of peatland is related to the influence of ocean water on the hydraulic influence of terrestrial water. Therefore, peatland types and their distribution characteristics in space and time are obvious. This is for studying the Quaternary, especially the Holocene
