| 摘 要： | 以胶州湾20m以内浅水域为研究区域，并按照0～2m、2—5m、5—10m、10～20m的水深对其进行分区，利用Landsat-5 TM数据进行水深遥感。结果表明：各区分别建立线性回归模型反演水深的精度要高于不分区时建立的模型；无论分区与否，多波段组合模型的反演精度最高，且在既不是太深也不很浅的区域反演效果最好；新建立的多时相单波段模型反演水深的精度在水深较浅的区域精度有较大的提高。

| Abstract: | This paper took Jiaozhou Bay with the water depth less than 20 meters as a study are.It was divided into intervals of 0~2m,2~5m,5~10m,10~20m,and the water-depth was extracted from Landsat-5 TM data.The results show that the precisions of the bathymetry models constructed in sub-area are better than that constructed in the whole area;the precisions of the multi-band bathymetry model is the best in both sub-area and the whole area,especially in the area which is neither low nor deep(2~10m);the precision of th... |
