| 英文摘要 | Field spectra and water quality measurements were performed in Zhongshan City and its adjacent river network in the Guangdong-Hong Kong-Macao Greater Bay Area.The hyperspectral reflectance characteristic of the river network and its correlation with the concentration of two non-optical activity parameters Chemical Oxygen Demand (COD_(Cr)) and Total Phosphorus (TP) were analyzed.The results showed that the spectral reflectance of the river network was mainly affected by suspended particulate matter and chlorophyll-a.In the range of 500~680 nm,the spectral reflectance of the water had negative correlations with the concentrations of COD_(Cr) and TP.Compared with the single band,the reflectance ratio of the specific band had higher correlations with COD_(Cr) and TP concentrations.The reflectance ratio band combinations with the highest correlations with COD_(Cr) and TP concentrations are R_(675)/R_(794) and R_(690)/R_(815),respectively.The water quality retrieval models that depend on the band combination show good estimation accuracy,with 27.2% and 32.1% of the average relative errors,indicating that the hyperspectral technology has good potential application for non-optical activity parameters (COD_(Cr) and TP) retrieval in the river network of the Pearl River estuary. |
