| 摘 要： | 潮滩表层沉积物含水量是反映潮滩与潮水周期性作用并指示潮滩高程的重要指标,了解潮滩表层沉积物含水量是开发利用潮滩资源的重要工作之一。以江苏辐射沙洲为例,在对应于2000年4月的TM遥感图像成像时潮位特征的潮汐周期时,测量了两条断面的表层沉积物含水量,然后通过对辐射沙洲TM遥感图像的多种处理及其比较,找出了TM图像与潮滩表层沉积物含水量的相关系数绝对值最高的数字图像处理方法,然后再进行傅立叶变换等处理,并推算出可决系数较高的表层沉积物含水量推算模型。 |

| Abstract: | Surface sediment humidity of the tidal flat reflects the periodicity action of the tide,and it is connected closely with the elevation of the tidal flat.The remote sensing image of TM can show the surface sediment humidity fairly,so the elevation of the tidal flat can be deduced by the remote sensing image of TM,and it is very important to know the elevation of the tidal flat in studying the sands movement and using the tidal flat resources which can not be measured easily by traditional method because of t... |
