| 摘 要： | 以Landsat MSS、TM、ETM+影像和HJ1B CCD2影像为主要数据源,采用人机交互的方式提取了1983～2012年间的6期杭州湾海岸线。分别采用端点变化率(EPR)法和叠加分析法定量化计算了岸线变迁速率及陆域面积变化,并按照地级市分岸段进行了岸线变迁分析。结合相关资料,开展了杭州湾南岸和北岸的变迁驱动力分析。结果表明:杭州湾沿岸以人工岸线为主,岸线变迁剧烈,变迁速率分布不均,绍兴市、杭州市、宁波市、嘉兴市、上海市围填程度依次降低。人类围填是杭州湾海岸线变迁的主要驱动力。

| Abstract: | In this study,Landsat and HJ1B satellite images from Hangzhou Bay were used to extract six periods of shorelines from 1983 to 2012. And the end point rate ( EPR) and overlay analysis were respectively used to estimate the rate of shoreline changes and the area of land changes caused by shoreline changes. Specifically,we divided the Hangzhou Bay shoreline into five parts to analyze the historical shoreline changes. Furthermore,with additional data,we tried to find out the causes of the shoreline changes. |
