| 摘 要： | 由于潮滩范围广、变化频繁、缺乏常规的地形测量资料,给潮滩开发建设带来极大不便.以伶仃洋大铲湾为研究区,使用美国陆地卫星MSS,TM及ETM三类数据源,共计17个时相,时间跨度为1978～2001年,在国内首次利用多时相卫星遥感图像水边线高程反演技术,确定了大铲湾岸线变化,并进行了滩涂分带及面积的估算、滩涂利用状况及淤涨速度的确定、不同部位潮滩坡度及淤积速度的反演,为深圳港大铲湾的开发建设提供了理论依据.

| Abstract: | The development of beach is not convenient owing to the fact that it spreads widely and varies frequently, and routine topography data lack.The Dachan Bay of Lingdingyang estuary is taken as research area,and data resources such as MSS,TM and ETM are provided by American Landsat,the time span of these data is from 1978 to 2001,totaling 17 time span The shoreline variation of the Dachan Bay,beach zoning and its area estimating,beach utilization,and velocity of deposition are determined for the first time in China by applying waterside line elevation reverse technology based on multi-temporal satellite remote-sensing images.The gradient and the deposition velocity of the target beaches at different locations are successfully reversed.The research conclusion provides the theory foundation for the develpment of the Dachan Bay in the Shenzhen Harbor. |
