| 摘 要： | 较为系统地研究了赤潮生物水体反射率曲线获取方法。通过对 2类反射率反演方法得出的反射率曲线与实际反射率曲线进行比较 ,得出在不具备大气环境参数的情况下 ,经验线性法的反演结果与实际反射率曲线最接近的结论 ,并进一步对正常海水和赤潮生物水体的光谱特性进行分析 ,提取出赤潮生物水体的特征光谱。这是进行赤潮监测和识别的重要前提

| Abstract: | The methods for obtaining the reflectance curves of red tide organism water body are systematically studied. It is shown from the comparison between the reflectance curves obtained by two kinds of inversion method and the actual reflectance curves that the inversion results obtained by the empirical linear approach are the most approximate to the actual reflectance curves. Furthermore, the spectral characteristics of normal seawater and red tide organism water body are analysed to extract the characteristic spectra of red tide organism water body, which are important prerequisite for monitoring and identifying the red tide. |
