摘　　要：本文描述了1989年11月在青岛即墨岙山养殖基地所做的海水叶绿素σ浓度遥感测量的基础实验。该实验获得了高浓度叶绿素α含量的海水反射光谱。该反射光谱的特征波段为:波谷在485nm;波峰在450nm 和535nm;“节点”在572nm.根据该实验数据选取了叶绿素α浓度两种双波段估算模式.分析结果表明;两种模式的精度都在50%以上,且双波段反射率的差值法优于双波段反射率比值法.This paper describes an experimental study on estimation of chlorophyll a concentration in seawater by the remote sensing technique.The reflection spectrum of the seawater with high chlorophyll a concentration was obtained in Aushan Cultivation Base on 11—13 Nov.1989. The characteristic wave bands of the spectrum are that:the wave trough of the spectrum is at 450nm and 535nm,the crest is at 485mn,and the“nodal point”is at 572nm.According to the data of the experiment,two models of twin bands on estimation of chlorophyll a concentration are established and compared.The results show that the accuracies of the two models are all more than 50% and the model of the reflectance difference between twin wave bands is better than that of reflectance ratio.
