摘　　要：分析了５７组含沙水体光谱反射曲线特征，定量描述悬浮水体光谱反射峰 值处波长的“红移”现象。在此基础上得出黄河口区野外实测悬浮体含量与光谱反 射率呈较好的相关关系，相关系数为０．８９，且在４个波段中，ＭＳＳ７相关系数最低， ＭＳＳ６最高。因而用分段回归或复相关模式来研究悬沙含量，效果较好。文中最后 讨论了提高遥感信息－悬沙相关关系精度的方法，提出增加参与回归模型参数的设 想，特别是增加悬沙粒度参数。The 57 spectral reflectance curves of suspended matter waters whose contents range from 10 mg/1 to 7079. 5 mg/1 are analysed. The result is that the logarithm value of the suspended matter content in waters has high relationship with the wave length in the maximum reflectance, and the correlation coefficient is 0.9. The suspended matters content also has high correlation coefficient with its spectral reflectance. The spectral reflectance of suspended matter waters in the Huanghe River Estuary were surveyed in 1984 and 1989. They gave the same results, and its correlation coeffieient is 0. 89, similar to those for the Yangzijing River Estuary, the Pearl River Estuary, the Miniing River Estuary and some lakes in Japen.
