摘要
以武汉市的主要供水水源地水质参数(氨氮)为研究对象,利用某时段的实测数据和遥感影像数据,尝试性地建立了氨氮含量的回归反演模型。精度和可用性检验结果表明,氨氮模型的反演精度较好,最大平均相对误差为10.02%,最小为6.28%,可以用来进行氨氮含量参数的反演。
The water quality parameter （ammonia nitrogen） from drinking water source areas of Wuhan City was collected, and a regression retrieval model of ammonia nitrogen concentration was experimentally established with interval monitoring data and remote sensing image data. The precision and the usability examination showed that the retrieval precision of the model was good, the largest and smallest average relative errors were 10.02% and 6.28% respectively. The model could be used for retrieval of ammonia nitrogen concentration parameter.
