摘要: 辽宁省泥炭的成因类型有陆相的沟谷类和河谷类,海陆交互相的河口类和海滨类.泥炭区域分布不平衡,辽东山地丘岭区为泥炭丰富区;辽南丘陵沿海为泥炭多量区;辽西山地丘陵及辽中平原区为泥炭少量区.从新构造运动与地貌、水文、海进海退和气候4个方面对泥炭分布的控制因素进行了探讨.Abstract: Peat is a kind of important organic mineral resources. The research and development on peat has made a great progress in agriculture, animal husbandry, industry, gardening, environment, medicine and other fields. There are abundant peat resources in Liaoning Province, with a total reserves of 35 362 700 tons, mostly in herbaceous nutritional type, formed in Middle and Late Holocene. The genetic types are gully, valley, estuary and seacoast. The peat is rich in Eastern Liaoning mountainous area, abundant in Southern Liaoning coastal hills area, and less in Western Liaoning mountainous area and Central Liaoning plain area. The controlling factors of the peat distribution are discussed on the neotectonic movement, geomorphology, hydrology, marine transgression and regression, and climate.
