中文摘要：

在曹妃甸近海水体实测光谱数据分析的基础上，与同步采集的水体悬浮泥沙浓度进行相关分析，选用合适的TM数据的遥感变量参数，根据2008年实测的四个剖面29个站点的海洋水色数据建立了水体悬浮泥沙浓度与TM数据对应的遥感定量反演模型，并用18个独立样本点进行了精度评价。研究结果表明：曹妃甸近海水体光谱曲线基本呈现单峰现象，敏感波段位于450—700nm范围内，最大波峰位于550nm附近，同时在600—700nm之间存在弱小的波峰，但最大峰值不明显；不同的地区，遥感敏感波段的选择有所差导；反演算法各地区不通用；误差计算结果表明，本区域TM3与SSC的二次多项式模型、TM3／1与SSC的二次多项式模型、主成分前三分量线性方程模型定量反演效果比较理想，反演结果能客观地揭示本区域悬浮泥沙的浓度分布及其变化特征，为今后对该海域悬浮泥沙运动规律的深化研究奠定了基础。

英文摘要：

On the basis of analysis of the field survey data reflected spectrum characteristics on Caofeidian coastal waters, we have done the correlation analysis with the synchronous pick suspended sediment concentration （SSC）and the remote sensing parameters of suspended sediments have been marked by selecting TM available channels in this paper, and the relevant inversion model of quantitative remote sensing data monitoring for suspended sediments has beech established with ocean color data measured from four sections of twenty nine stations on Caofeidian coastal waters in 2008, And carried out precision evaluation with the 18 independent samples. The results show that ： the reflected spectrum characteristics of Caofeidian coastal waters showed basically single-peak phenomenon, sensitive band located within the 450-700nm, maximum peak located in the vicinity of 550nm, and it＇ s the existence of the weak peaks within the 600- 700hm, but the biggest peak is not obvious ; different regions, remote sensing sensitive to the choice of band is different and aLso the inversion are not common; the results of the error show that the quadratic polynomial of TM3 and SSCg and TM3/1 and SSCg, the linear equation of the first three components of principal component are comparatively an ideal, and the remote sensing quantitative model has gained a good effect and high accuracy, and can fulfill the quantitative survey of the distribution and variation of suspended sediments in the coastal waters of Caofeidian. Finally, the results will be considered as a basis for further research in this region.
