水质遥感是环境遥感领域的热点和难点问题。影响内陆水质遥感精度的因素很多。本文评述了国内外内陆水质遥感监测中存在的突出问题和影响水质参数信息提取精度的一些关键因素。内陆体光学特征的复杂性体现在水体成分的独立性上，水组分信号的特征光谱和耦合效应的相似性以及水光的时空变化。大气校正的不确定性体现了大气气溶胶光学特性的变化和波面反射光校正的不确定性。生物光学模型的复杂性和地域性要求复杂的反演算法。对于多源遥感数据协同反演，模型验证的尺度效应和不确定性明显。内陆水质遥感不同于海色遥感，要求遥感数据具有较高的空间分辨率、光谱分辨率和时间分辨率。因此，该模型具有较高的空间分辨率、光谱分辨率和时间分辨率详细讨论了现有卫星传感器在内陆水质监测中的性能局限性，指出了这些因素的复杂性和综合性，指出了内陆水质遥感研究的重点和发展方向。
Water quality remote sensing is the hot and difficult topic in the field of environment remote sensing.Various factors affect the improvement of inland water quality remote sensing precision.This paper comments on the outstanding problems existing in inland water quality remote sensing monitoring and some key factors influencing the water quality parameters information extraction precision both at home and abroad.The complexity of the optical characteristics of inland body embodies the independence of the water body components,the similarity of the characteristic spectrum and the coupling effects of water components signal and together with the temporal and spatial variation of the water optics.The uncertainty of atmosphere correction embodies the variation of atmospheric aerosol optical characteristics and the uncertainty of correction of reflected light from wave water surface.The complexity and regional characteristics of bio-optical models demand complex inversion algorithms.The scale effects and uncertainty of model validation are obvious for multi-source remote sensing data cooperative inversion.Inland water quality remote sensing differs from ocean color remote sensing,which demands remoted data with high spatial resolution,spectral resolution and temporal resolution.Therefore,the performance limitations of the available satellite sensors in inland water quality monitoring were discussed in detail.All the above-mentioned factors were complicated and integrated.The emphases and the development direction of inland water quality remote sensing were pointed out.
