| 摘 要： | 本文采用高分辨率层序地层学理论,运用气候旋回、基准面升降旋回,以及海平面升降旋回在区域上等时的原理,对研究区46 km2中的23个钻孔及两条全新世剖面进行了高精度的对比研究及沉积环境分析,对跨湖桥人的生态环境进行了深入的研究,得出8000 aBP跨湖桥人生活的地貌环境、植被、动物、气候已与现今基本一致,跨湖桥人突然"消失",是由于海平面上升,遗址被淹而致。直至3000 aBP海水还未从本区退出,所以先人不可能迁回,从而显示出某种"神密"色彩。

| Abstract: | Based on the high resolution stratigraphic sequence stratigraphy theory and the principles applicable to conditions as to when climate cycle and ascending and descending cycles of the base level and sea level are over the whole region,this paper carried out a comparative study with high precision and sedimentary environment analysis of 23 drill holes and 2 holocene sections within 46 km2 of the region of interest,and also made an in-depth investigation of the ecological environment for the ancestors living ... |
