摘　　要：结合国际照明委员会(Commission International de l’Eclairage, CIE)颜色系统,首先利用基于卫星多光谱遥感反射率的色度角信息获取方法,得到色度角信息数据集;然后,将色度角数据集与航测数据集匹配,建立基于色度角信息的总叶绿素和悬浮颗粒物浓度反演模型;最后利用现场采集的辽宁大连附近海域高清数码图像进行验证。结果表明:基于色度角信息反演得到的叶绿素a质量浓度、悬浮颗粒物质量浓度的反演模型精度较高,二者与色度角的相关系数R^(2)分别为0.73、0.81,且均与色度角呈负相关关系。该模型可以与无人机、数码相机等系统联动,并与卫星遥感组成立体监测系统,为海洋水质环境监测提供一种新方法。Combined with the Commission International de l ’Eclairage(CIE) color system, the hue angle information acquisition method based on satellite multispectral remote sensing reflectance was used to obtain the hue angle information data set. Then the hue angle data set was matched with the survey dataset to establish a inversion model of total chlorophyll and suspended particulate matter concentration based on the hue angle information. Lastly, the high-definition digital image of the Dalian sea area was used for verification. The results show that the inversion model of chlorophyll a concentration and suspended particulate matter concentration based on the hue angle information has high accuracy, and the correlation coefficients R^(2) between the two parameters and the hue angle are 0.73 and 0.81, respectively, and both of them are negatively correlated with the hue angle. The proposed model can be integrated with drones, digital cameras and other systems, and combined with satellite remote sensing to create a three-dimensional monitoring system for providing a new method for marine water quality environmental monitoring.
