| 摘 要： | 利用厦门湾地区遥感图像及准同步实测泥沙资料,进行相关和回归分析.结果表明,采用两种比值组合作为遥感参数,与表层含沙量作二次曲线回归,可以得到精度较高的模型.利用两种比值模型构建最佳组合模型,提高了模型预测精度,将其作为悬沙遥感反演的最优模型,由此得出了研究区域悬沙分布图.

| Abstract: | According to the remote sensing images and sediment concentration data acquired quasisynchronously, correlation analysis and regression analysis are made, the results of which indicated that using two kinds of band ratios and silt concentration, two conic regression model which have a high precision can be worked out. By the combinatorial model established based on the two models, a higher forecast precision is acquired. Using this model as the best inversion model to derive the suspended sediment distribution of the estuary, the distribution diagram of suspended sand at the research area is obtained. |
