The refiectivity of water body was obtained through processing remote sensing images of water body in Dalangdian reservoir of Cangzhou. The correlativity between reflectivity of water body and measured dissolved oxygen content was analyzed, the multiple spectra model of dissolved oxygen content and TM2 + TM3 was constructed and the constructed model was inversed and verified. The results were relatively consistent with actual condition, indicating that the constructed model could be used to monitor the dissolved oxygen content of water body in Dalangdian reservoir.%对沧州大浪淀水库水体遥感影像进行处理得到水体反射率,分析水体反射率与实测溶解氧含量的相关性,构建了溶解氧含量与TM2+TM3的多光谱模型,并对模型进行了反演和验证.结果与实际情况较吻合,说明所建立的模型可用于大浪淀水库水体溶解氧含量监测.
