泥炭是地球冰河后退期进入温暧期间沼泽地带的特有产物。由于所处沼泽地特点不同,地势差异和气温高低,形成泥炭的原始植物体群落差异,使泥炭分为三大类:高位泥炭,主要群落为苔藓植物,其特点是具有弹牲,在原始泥炭挖出时用手攥紧,流出来的水清亮,矿物质含量低,手一松还如原状;低位泥炭原植物群落是芦苇、苔草等,分解度高,呈黑色或黑褐色,原始泥炭挖出用手攥紧,流出的是带有泥浆的污浊水,矿物质含量较高,微有弹牲;中位泥炭介于两者之间。泥炭的组成是由没有分解的植物残体或分解到一定程度中止,而保持原来细胞特点的物质;植物体分解到失去细胞结构变成有色物质及矿物质。
Peat is a peculiar product of the glacier retreat into warmth during the marshes. Because of the characteristics of the swamps, the difference in topography and the temperature, the difference of the original plant community of peat is formed, and the peat is divided into three categories: high peat and the main community is bryophyte, which is characterized by bullets, When digging out, it is clenched by hand and the water flowing out is clear and bright. The content of minerals is low and the hands are still as loose as before. The low-lying peat plant communities are reed and Carex, which have high disintegration degree and are black or dark brown, Dug out by hand clenched, out of the muddy muddy water, high mineral content, a slight bullet; the middle of the peat in between. Peat consists of decomposed plant residue or decomposition to a certain extent suspended, while maintaining the original characteristics of the cell material; plant decomposition to the loss of cellular structure into a colored material and minerals.
