Based on remote sensing data acquired in different periods ,by radiometric calibration ,geometric correction and band synthesis processing ,etc ,this paper explained the reclamation process of Hangzhou Bay Andong Beach in different periods ,and discussed the tidal change trend under the background of reclamation using the foreshore terrain in corresponding period .The results showed that Andong Beach reclamation showed an obvious “slow to fast” phased development characteristics . ①1984—1995 was the slow development stage when reclamation rate was 1.19 km2/a; ②1995—2004 was the steady development stage with a reclamation rate of 6.65 km2/a; ③2004—2013 was the rapid development stage , when reclamation rate reached 17.69 km2/a . In the rapid development reclamation stage ,0 m contour line moved constantly close to the sea ,but the -5 m contour line remained essentially unchanged .Under the land reclamation background , -5 m contour line shallow beach area showed a decreasing trend ,indicating that the beach reclamation rate was greater than the beach silting up rate .%基于不同时期遥感影像数据，通过辐射校正、几何校正和波段合成等处理，解释不同时期杭州湾庵东边滩围垦过程，并结合相应时期的滩涂地形，探讨围垦背景下的滩涂变化态势。结果表明：近30 a来庵东边滩围垦呈现明显的“由慢至快”的阶段性发展特征：①1984—1995年为缓慢发展阶段，围垦速率为1.19 km2／a；②1995—2004年为稳步发展阶段，围垦速率为6.65 km2／a；③2004—2013年为高速发展阶段，围垦速率为17.69 km2／a。围垦高速发展阶段，0 m等高线不断向海淤进，而－5 m等高线基本保持不变。在围垦背景下，－5 m等高线以浅滩涂面积呈减少态势，表明该区域围垦速率大于滩涂淤涨速率。
