| 摘 要： | 渤海湾沿岸的海陆过渡带，优越的水文地理环境有利于泥炭沼泽的形成与发育。海洋海退导致的海岸线变迁，是控制泥炭沼泽发育时间和空间分布的主导因素。间冰期和冰后期的海面上升期间，自海向陆发育了海侵基底泥炭；中全新世高海面期，在山前扇缘洼地和沟谷有泥炭沼泽发育；晚全新世海面下降期，泥炭沼泽主要发育在沿岸的海湾、泻湖、三角洲汊河间洼地及平原上的河滩、阶地、古河道等地。

| Abstract: | In the sea- land transitional zone in the coastal area of the Bohai Bay ,the advanta-geous hydrogeographical environment contributes to the formation and development ofpeat moor. The migration of coastline resulting from transgression and regression is theleading factor to control the time-space distribution of the peat. During sealevel rising inthe interglaciation and the deglaciation,the basal peat developed from sea to land. Andduring the high sealevel period in Middle Holocene, peat moors developed in somegulleyes and depressions on mountain-front fan margins. And during sealevel drop inLate Holocene, peat developed in bays and lagoons along coast,in deltaic interdis-tributary sags and also in river flat,terrace and ancient channels in the coastal plains. |
