【摘要】利用1986年以来8个时相的TM/ETM+遥感资料,调查杭州湾围垦淤涨情况。在几何校正、图像拼接的基础上,提取多时相的岸线;利用GIS空间分析功能,分析岸线动态变化、围垦淤涨状况及其趋势。结果表明,1986年以来杭州湾岸线演化主要是由人工围垦和滩涂养殖引起。更多还原

【Abstract】 This paper describes the investigation of inning and silting in Hangzhou bay using 8 times TM/ETM~+ since 1986. Remote sensing image processes including geometric correction and false color combination and mosaiking were carried out before deriving shorelines. Then the information of shoreline dynamic changes, inning and silting was obtained by utilizing the space analysis function of geographical information system (GIS). The results show that the shorelines of Hangzhou bay have been changing since 1986 mainly due to manual inning and beach breeding. The investigation also reveals that the manual projects are carried out on the basis of planning.更多还原
