滩涂资源是浙江省重要的后备土地资源，及时掌握滩涂冲淤演变的动态对滩涂的开发利用有重要的意义，遥感是获取滩涂冲淤演变的重要手段。本文采用1981年MSS数据、1995、2009年TM和2013年高分1号卫星数据，结合潮位资料提取杭州湾南岸慈溪段的年平均高、低潮特征线，并进行GIS对比分析。结果表明，1981-2013年研究区大部分断面为淤长，且主要集中凸出岸段，而两边淤长速度减慢，有的呈侵蚀状态。平均高低潮特征线附近滩涂处于淤长状态，形状为凸型，各个断面的淤长速度各有不同，主要表现为中间凸起部分淤长速度最快，往两边次之。1981年至2013年慈溪段滩涂面积逐渐增长，呈现为淤积状态,1995年和2013年滩涂面积分别是1981年和2009年近一倍，引起滩涂冲淤演变的主要原因是由于输沙通道的变化，以及人类开发资源活动的加剧，研究表明遥感和潮位信息结合可以实现滩涂冲淤变化的连续分析。

The tidal flat is important land reserve resource in coastal areas as the population continues to increase and the cultivated land resources in coastal areas decrease sharply. It is very important to master the erosion and deposition variation dynamic of the tidal flat.Remote sensing can judge erosion and siltation situation of the tidal flat accurately. This paper takes part of Hangzhou Cixi tidal flats in Hangzhou Zhejiang province for study area, and extract the average high and low tide characteristic line by using MSS in year 1981, TM in year 1995 and 2009, and GF satellite in 2013 and combing with tide level. The results showed that the tidal flat which is situated in the average high and low tide characteristic line is the deposition from 1981-2013. Because the shape is convex, the deposition speed in every section is different, and the degree of deposition speed in the middle section is more than the both sides of the bulge. The deposition area increase from year 1981 to year 2013, and the tidal flat area in year 1995 and year 2013 are nearly doubled in 1981 and 2009 respectively. The cause of tidal flat spatial evolution is due to sediment transport channel and the rise and fall of transfer, and human resource development activities intensified.
