摘　　要：环境一号卫星CCD数据具有获取周期短、空间分辨率高的特点,在内陆湖泊水质遥感监测方面具有很好的应用前景。通过与卫星同步的地面试验,建立了适用于东湖水体叶绿素浓度遥感反演模型,使得遥感数据的反演结果与地面测量一致,结果表明,东湖水体叶绿素浓度具有明显的时空分布特点,东湖东部水质和北部水质较好,南部和西部水质较差,这为东湖水质的治理提供了有效的参考依据。Environment No.1 satellite CCD data have characteristics of short time obtaining and high spatial resolution,which have a huge potential prospect in inland lakes water quality remote sensing.The remote sensing inversion model for Donghu Lake chlorophyll concentration was established through ground experiment.The results showed that Donghu Lake chlorophyll concentration has obvious spatial-temporal distribution characteristics,the water quality of east and north of Donghu Lake is better than that of south and west of Donghu Lake,which will provide effective reference basis for control of Donghu Lake water quality.
