以沧州大浪淀水库作为研究对象,将实测的高锰酸钾指数和 TM 多光谱遥感数据反射率进行回归分析处理,构建了高锰酸钾指数多光谱定量遥感模型,并对 TM3/TM5 波段指数模型进行了定量反演,其结果符合水体实际水质分布情况,表明所建模型可应用于该水体高锰酸钾指数的监测.%With Dala1tgdian Reservoir in Gangzhou as the research obtcct. the measured CODma. and TM remote scnsing data reflectivity were reated by regression analysis, the multi-spectral quantitative model for CODma. was constructed, the TM3/TM5 waveband index model was quantitatively inverted, and the results were in accordance with the actual distribution of water quality, which indicated that the model was apolicable to the monitoring of CODma in water.
