| 摘 要： | 河口悬浮泥沙反射率渡谱特性研究是悬浮泥沙遥感定量分析的基础工作。不同水域悬浮泥沙物质成份、粒径分布和浓度的不同,其相应的反射率波谱特性也有所差异。对此,国内外尚未建立起具有普适型的算法模式,用以处理不同水域的悬浮泥沙遥感问题。鉴于此,我们于1991年9月6～11日对胶州湾大沽河口区进行了现场悬浮泥沙波谱特性实验。由此建立了大沽河口悬浮泥沙落度SSC与陆地卫星TM_3和TM_4渡段相应的光谱反射率之间的数学模式。经过相关分析和误差分析的检验证明,由模式计算所得结果是令人满意的。

| Abstract: | In this paper, an algorithm has been developed for determining suspended sediment concentration in the surface water of Dagu estuary using satellite data and some reflectances have been correlated with suspended sediment concentration. Through correlation and error analyses, a correlation coefficient which is bigger than 0. 95 has been gained. We think the result is good. In addition, we also found that the peak Wavelength of spectrum reflectance moves toward long wavelength with increase in suspended sediment concentration. |
