泥炭,又称“草炭”或“泥煤”,是成煤作用初级阶段的产物,由沼泽植物残骸在空气不足和大量水分存在的条件下,经过不完全分解而成。因此泥炭中可以见到许多没有完全分解的树枝、树叶和树皮等植物残体。全球性的泥炭,绝大部分是在42000年前形成的,局部地区近代仍有泥炭堆积。 在自然状态下,泥炭由水、矿物质和有机质三部分组成,其中有机质占固相物质的50％左右。有机质由未完全分解的植物残体和腐殖质 Peat, also known as “peat” or “peat”, is the product of the primary stage of coal formation, which is formed from incomplete decomposition of marsh plant debris in the presence of insufficient air and large amounts of moisture. Therefore, peat can see many not completely decomposed branches, leaves and bark and other plant residues. Most of the global peat was formed 42,000 years ago. Peat accumulation still exists in some areas in modern times. Under natural conditions, peat consists of water, minerals and organic matter, of which organic matter accounts for about 50% of the solid material. Organic matter consists of incompletely decomposed plant residues and humus
