根据2003年1月份珠江口实测资料获得了适合该海域的相关参数,建立了适用于该海域的二类水体水色三要素优化反演模型,同步优化反演得到了与2003年1月25～26日实测站点相对应的2003年1月29日的SeaWiFs图像像元点的水色三要素,反演与实测水色三要素的平均相对误差分别为:叶绿素14.9%,悬浮泥沙12.1%,黄色物质13.6%。研究结果说明本研究建立的优化反演模型比较适用于珠江口二类水体水色三要素的反演,且具有较高的反演精度。
Based on the measured data of Pearl River Estuary in January 2003, the relevant parameters suitable for the sea area were obtained, and the three-factor model of aquifer color inversion for the second type of water body suitable for the sea area was established. Simultaneously, The average relative errors of the three factors of inversion and measured water color were respectively 14.9% for chlorophyll, 12.1% for suspended sediment and 13.6% for yellow matter, corresponding to the three elements of water color of SeaWiFs image pixel on January 29, 2003 corresponding to the measured stations. %. The results show that the optimized inversion model established in this study is more suitable for the inversion of the three elements of water color in the second-class water bodies in the Pearl River Mouth, and has higher inversion accuracy.
