| 摘 要： | 悬浮泥沙含量的时空分布是分析河口海岸冲淤变化、估算河流入海物质通量、研究海洋沉积速率和海洋环境的重要参数.成像光谱仪技术包含了丰富的空间、辐射和光谱三重信息.用中国神舟三号上34个波段的中等分辨率成像光谱仪（CMODIS）数据,采用经验线性法对其辐射亮度值进行了反射率转换,结合长江口现场调查资料,对长江口悬浮泥沙含量时空分布进行了遥感定量反演,取得了很好的效果.

| Abstract: | Spatial and temporal distributions of suspended sediment concentrations are greatly important for analyzing the deposition and erosion variety of the estuary and coast,evaluating the material fluxes from river to sea,and studying oceanic sediment velocity and environment.The spectrometry imagery technology includes three kinds of spatial,radiation and spectral information.The Chinese Moderate Resolution Imaging Spectroradiometer(CMODIS) with 34 bands was loaded on the China's SZ-3 spacecraft on March 25,2002.Making use of the CMODIS data,this paper presents the retrievals of the suspended sediment concentrations and its spatial and temporal distributions in the Yangtze River estuary with the field measurements. |
