为了分析卫星MODIS影像数据计算水体浊度的精度,探索利用卫星遥感数据监测水体水质的方法,以武汉东湖为研究区域,布置了水体浊度监测点。利用光谱分析法,将MODIS影像的光谱数据转化为浊度数据,并与地面准同步悬浮物浓度实测数据进行比较分析,建立了适合东湖水体的悬浮物浓度遥感定量估算模型。模型估算结果表明,根据MODIS影像数据所得的水体浊度数据精度满足相关要求,MODIS数据应用于湖泊水体悬浮物浓度监测具有可行性。

In order to analyze the accuracy of water turbidity calculated by satellite MODIS data and explore the water quality monitoring method by using satellite remote data, water turbidity monitoring points were arranged in the research area of Donghu Lake. By spectrum analysis, the spectrum data of MODIS images are converted to turbidity data and compared with the quasi-synchronously measured suspended matter concentration in Donghu Lake, and the quantitative estimation model of suspended matter concentration appropriate to Donghu Lake is established. The model estimation results show that the water turbidity accura-cy obtained by MODIS image data can meet the correlative requirements, and it is feasible for the application of MODIS data in monitoring the suspended matter concentration of Donghu Lake.
