简介：推迟的沉积的遥感上的量的申请是遥感学习的设计申请的一个重要方面。在这份报纸，厦门海湾被选择为学习区域。遥感数据的十一个不同阶段被选择建立一个量的遥感模型由使用遥感图象和伪同步的测量沉积数据印射推迟的沉积。基于开发的实验统计是在即时推迟的沉积集中和集中以及变换在表面层之间建模的平均tidally的推迟的沉积之间的变换模型推迟的沉积集中和平均深度的推迟的沉积集中。在这个基础上，量的应用程序推迟的沉积的遥感上的综合模型被开发。由象多时间的遥感图象一样使用这个模型，平均的多年推迟了厦门海湾的沉积集中被预言。在模型预言和多年平均的观察数据表演之间的比较象附近的地点的集中差别一样推迟了学习地点的沉积集中能被遥感模型很好与21.61%的错误率或更少预言，它能满足隧道免职计算的设计要求。
