本文结合笔者几年来对不同类型泥炭沼泽分布区界的实地考察,分析了世界各地与泥炭形成有关的517个气象站的水热气候指标的相互关系。确定了泥炭形成的水热系统指数。划分了不同类型的成炭气侯区。并依此对现代泥炭的成因、分类进行了系统分析。

According to the principal plant of peat formation, the peat-bog is divided into two types. One is low-moor in which principal plants of peat formation are herb and woody plants. The other is high-moor in which principal plant is sphagna. The climate only suitable to the development of low-moor is named the low-moor peat formation climate, the climate suitable to the development of both high-moor and low-moor is named the high-moor peat formation climate.The paper has counted T and K values (from 1961 to 1970) from 517 meteorological stations throughout the world and established ail equation of the water and heat system for peat formation, i.e. Z=5.7K+12.8-T, regarding daily average temperature in the period in which the temperature equals 10℃ more orless (T) as heat index and humid coefficient by M. H. as water index.
