中文摘要：

通过对研究区35个站位全新世中期以来泥质体沉积厚度和形成年代的统计分析,认为泥质体主体主要形成于7.0cal.kaBP前后,伴随着黄海最高海平面出现,此后海平面波动幅度极小,沉积环境比较稳定,黄海暖流开始入侵并形成了黄海现今的环流格局,细粒物质被近岸海流所携带向岸向海双向传输,发育了山东半岛南部近岸（沉积厚度7.7m）和南黄海中部（最大沉积厚度9.0m）两个沉积中心。物源上以现代黄河和老黄河物质为主,同时,长江物质、朝鲜半岛物质、山东半岛沿岸短源河流物质,甚至外海的再悬浮物质对泥质沉积也有一定的贡献。两个沉积中心的最大沉积速率分别为1.283和1.286mm/a,之所以与以往研究区百年尺度的沉积速率有显著差别,可能与地史时期泥质体的沉积压实作用及黄河数次改道造成的物源供应不稳定等因素有关,但最大沉积中心位置在百年和千年尺度上的表现是吻合的。

英文摘要：

The thickness and forming age of the Holocene mud deposits are studied with the thirty-five cores collected from the Central Yellow Sea. Our results suggest that the pattern of Yellow Sea Warm Current was formed simultaneously when the sea-level reached its maximum at 7.0 cal. kaBP. and has remained stable with little fluctuation since then. Fine sediments were transported by the coastal current to the near- shore and offshore areas, and lead to the deposition of mud deposits in two depositional centers： the off- shore area of Southern Shandong Peninsula （thickness 7.7 meters） and the Central South Yellow Sea （thickness 9.0 meter maximum）. The fine sediments are mainly supplied by the modern and old Yellow River, and at the same time, the Chang]iang River, Korean Peninsula, small rivers and coastal sediments around the Shandong Peninsula as well as the suspensions from the outer-seabed erosion also have certain contribution to the mud supply. The maximum depositional rate of the two centers is 1. 283 and 1. 286 mm/a respectively. Obvious difference of sedimentation rate in scale of hundred years is observed. It is probably related to the compaction of mud deposits and unstable sediment supply owing to the diversions of the old Yellow River in the history. The two depositional centers has retained in stable. High resolution research of palaeoenvironment changes in the mud area is required on the basis of this study.
