总氮质量浓度是衡量水环境的主要指标之一.以粤西海域为研究对象,将实测的总氮质量浓度和水体高光谱遥感反射率数据进行回归分析处理,结果表明:无论是单波段,还是波段因子,总氮质量浓度与水体高光谱遥感反射率的相关性仅达到0.593;研究区域的总氮和悬浮物具有较好的相关性,相关系数最高可以达到0.76.通过悬浮物间接的遥感监测粤西海域的总氮是一个有效的途径.

The total nitrogen concentration is an important index to measure water environment. Taking the sea waters of the west Guangdong as the research object, the measured total nitrogen concentration and hyperspectral remote sensing reflectance data were processed by regression analysis. The results shows that the total nitrogen concentration has a little correlation with hyperspectral remote sensing reflectance data, and the correlation coefficient only reaches 0.593. The total nitrogen and total suspended solids of the study area has a high correlation, and the highest correlation coefficient can reach 0.76. Therefore, it is an effective way to monitor the total nitrogen by monitoring the total suspended solids in the waters of the west Guangdong.
