摘要
在分析小海潟湖沉积物的粘土矿物组合特征、化学元素含量变化规律以及pH值、有机质含量等一系列指标的基础上,总结出山东半岛东北部沿岸6000a以来的气候、海平面变化曲线,概括出这一区域6000a以来的环境演变大致经历了:6000～3400a BP气候温暖湿润,相对海平面较高时期;3400～1600a BP气候趋向干凉,海平面相对较低的过渡时期;1600aBP以来气候温湿,海平面有上升趋势的时期.
Based on analysing the sediment geochmical characteristics, the environment change of the studied area since 6000 a B P is studied.1) The environment fluctuated mainly in accord with the climate change,the general tendency of which is from warm-humid to cool-dry and then meso- thermal-humid,with the warmer intermissions,at the times of 3400 a B P, 1600 a B P.2)The transyressions and regressions of the coast undergo the same rythume of the climate change,but somewhat lagged behind.
