摘　　要：在全国泥炭资源调查的基础上(1983～1985年),结合中国科学院东北地理与农业生态研究所与有关单位多年来在全国各地泥炭调查的成果,根据泥炭的蕴藏形式、泥炭地有机碳的丰富度、泥炭地有机碳集中分布区的地貌单元和区域位置,将泥炭地有机碳按照埋藏类型和储量划分成3类(埋藏类、裸露类和裸露与埋藏兼有类)、5型(极丰富型、丰富型、较丰富型、贫乏型和极贫乏型)和31个分布区。中国泥炭地的蕴藏类型主要为裸露类,主要分布在青藏高原东部的若尔盖高原以及东北地区的山地丘陵,包括5型12个分布区;其次是埋藏类,主要分布在长江中下游平原以及沿海平原,包括4型14个分布区;裸露与埋藏兼有类泥炭地主要分布在云贵高原、晋北张北地区,仅包括4型5个分布区。Base on the investigation of peat resources over China during 1983-1985 and the survey carried out by Northeast Institute of Geography and Agroecology, Chinese Academy of Sciences, the division of organic carbon reserves of peatlands in China was carried out. There are 3 buried forms for organic carbon in peat- lands, so the peatlands were divided into bared peatland, buried peatland and bared-buried peatland. The 5 cat- egories including extremely abundant, abundant, relatively abundant, poor and extremely poor were graded by richness of organic carbon reserves; and 31 topographic areas by terrain features. Bared peatland is the main form ofpeatland in China, which is mainly distributed in Zoiga Plateau in which organic carbon reserves is ex- tremely abundant, the Daxingan Mountains in which organic carbon reserves is abundant, Xiaoxingan Moun- tains in which organic carbon reserves is abundant, and the Sanjiang Plain in which organic carbon reserves is abundant. Buried peatlands are mainly distributed in the Middle and Lower reaches of Yangtze River Plain and South Yunnan Plateau in which organic carbon reserves is abundant, and the Songliao Plain in which or- ganic carbon reserves is relatively abundant. Bared-buried peatlands are mainly distributed in the Yunnan-Gui- zhou Plateau in which organic carbon reserves is extremely abundant, and Zangnan Valley in which organic carbon reserves is relative abundant.
