| 摘 要： | 辽宁海岸带,沙砾堤-潟湖体系沉积环境演化表明,冰后期由于气候变暖引起海平面上升,在9000aBP．左右海水开始侵入本区,8000—7000aBP．前的海平面约高于现海面1.5—2.5m。近5000年来,海面趋于下降过程中,并有波动和相对稳定时期。

| Abstract: | Changs' of sedimentary environment of the system of sand-gravel outer bar and lagoon in Liaoning coastal zone illustrated that the rising of temperature in the postglacial period had caused that of sea level. Since 9000 B.P. sea water has transgressed into this zone, and the sea level in the period of 8000-7000 B.P. was 1.5-2.5 m higher than that of present. Since 5000 B.P. it has tended to descend and experienced fluctuating and relative stable periods. |
