摘    要:基于高分辨率遥感图像,采用相似三角形原理,结合海岛多年潮汐数据进行了海岛潮间带的确定;利用克里格(Kriging)插值方法,对水深图中海岛浅水区域的水深点数据进行单元网格化处理,在遥感图像的辅助下,进行了海岛湿地范围的界定。在此基础上,确定了东沙岛潮间带和湿地的范围,提取了各自的面积,并对结果进行了分析。

关 键 词:潮间带  湿地  高分辨率  遥感图像

Abstract:Based on the high resolution remote sensing images, the island intertidal zone is determined by using the similar triangle principle and the multi-year island tide data, the Kriging interpolation method is used to grid the water depth data in the island shallow water area of bathymetric map, and the island wetland scope is then demarcated with the aid of remote sensing images. Based on the above-mentioned method, the Dongsha Island intertidal zone and wetland scopes are demarcated, their areas are measured, and the measured results are also analyzed.
Keywords:intertidal zone  wetland  high-resolution  remote sensing image
