中文摘要：

选用海南岛南部海区的EO-1 Hyperion高光谱遥感数据进行了浅海水深直接反演方法的研究。水深反演的关键问题是水体漫衰减系数的获取和海底底质的分类。通过主成分分析方法进行海底底部分类；应用QAA算法可以计算得到光学深水的漫衰减系数Kd，并对沿海光学浅水求硒的方法提出了修正方法，最终代入基于辐射传递理论的直接反演方法中计算得到浅海水深。结果表明直接反演方法能够较快得到水深结果，且能够与海图匹配。

英文摘要：

Using EO-1 Hyperion hyperspectral remote sensing data, the shallow-water bathymetry inversing in Hainan Island is studied. The key techniques in inversing the bathymetry are retrieve of sea water diffuse attenuation coefficient and classification of seabed. Principal component analysis method is used for seabed classification. The diffuse attenuation coefficient Kd is derived by using QAA algorithm which performs well in optical deep water. Kd obtained from QAA needs to be corrected in some coastal areas with optical shallow water and calculated by direct inversion based on radioactive transfer theory to obtain the bathymetry. It is concluded that the water depth derived from direct inversion can match with the marine map.
