摘　　要：以沧州大浪淀水库为研究主体,将水体TM影像与实测数据进行分析处理,得出水体反射率与水质参数相关性最高的波段组合,建立了悬浮物、总氮两种水质参数的遥感监测模型,并进行了反演和验证。结果表明所建模型满足了水库水质参数的动态监测需要,可以利用所建的模型来了解水体环境,采取措施,为附近地区人民生产和生活用水安全提供保障。Dalangdian reservoir,the water source of nearby irrigation and urban life,was used as the research object.The band combinations with highest correlation with water quality parameters were achieved through analyzing the TM images and live measurement data of water quality parameters;then the remote sensing monitoring model of SS and TN was established,inverted and verified.The results showed that the model could meet the need of dynamic monitoring of the water parameters in Dalangdian reservoir,and could make sure that residents know water environment timely.
