摘　　要：根据考古界提供的盐城市建军中路东汉至明代古水井清理资料,从环境考古学角度探讨了盐城地区自东汉至明朝的海面变化规律。盐城市建军中路清理的这批古水井自东汉至明朝在时间序列上衔接清楚,井底高程的变化反映了海面波动情况。研究表明,盐城地区自东汉至明代海面变化总的趋势是上升的,但存在200年尺度的升降波动,期间有4次峰值和3次谷值:秦汉时期(2kaBP)、中唐(1 3kaBP)、南宋(0 9kaBP)和明代(0 4kaBP)为高海面;南北朝(1 6kaBP)、晚唐(1 1kaBP)和元代(0 5kaBP)为低海面,海面波动幅度在1m左右。Based on the data of ancient wells from East Han to Ming Dynasty offered by archaeology circles at Middle Jianjun Road in Yancheng area and from the viewpoint of environmental archaeology, the authors discussed the sea-level changes from East Han to Ming Dynasty in Yancheng area. The height of the bottom of ancient wells discovered at Middle Jianjun Road in Yancheng reflects the sea level change because the wells have serial and complete time series from East Han to Ming Dynasty. The study shows that the general trend of sea level from East Han to Ming Dynasty was going up, but it had the fluctuation on a 200 a scale. During this period there were four peaks and three valleys: Qin and Han periods (2 kaBP), Middle Tang period (1.3 kaBP), South Song period (0.9 kaBP), and Ming period (0.4 kaBP) had high sea level, and Southern and Northern periods (1.6 kaBP), Late Tang (1.1 kaBP) and Yuan (0.5 kaBP) had low sea level. The amplitude of the sea level fluctuation is about 1 m.
