	长江大保护背景下，长江口水环境监测具有重大需求，迫切需要快速有效的监测手段增强监测能力。本文基于长江口现场实测和GOCI卫星影像，建立了水质参数反演模型，实现了总磷、总氮、化学耗氧量和溶解氧的遥感反演，具有较好的反演精度，进一步参考海水水质标准和地表水环境质量标准，对遥感反演的海域进行了水环境质量评价，长江口水域水环境质量较好，整体处于一、二类水水平，总氮略偏高为三类水。本文提出的水质监测与评价方法能够为长江大保护提供有力的技术支撑。<br />
Under the background of the great protection of the Yangtze River, the significant requirement is about ordinary survey of water environment around Yangtze estuary, so it is urgent to form a rapid and effective monitoring method of the water environment quality of the Yangtze River. Based on the results of Marine Environment Monitoring of Shanghai and the images of GOCI satellite, this study establishes models of the four important parameters of water quality, such as TP, TN, COD and DO and these models all have good precision. Based on the visualization of the inversion results and the observed data, this study assesses the water environment around Yangtze estuary and its adjacent waters using the water of the sea water quality standard and the surface water environment quality standard. This study finds that the water environmental quality of Yangtze Estuary is good; the overall water quality level is between grade 1 and 2 although TN is slightly higher than the grade 3. This study also provides technical basis for the prediction of water quality pollution and the protection of the Yangtze River.
