摘要
基于有毒赤潮藻的三维荧光光谱及主成分分析方法,针对我国东海常见的6种有毒赤潮藻建立了有毒赤潮藻活体荧光识别测定技术。根据Fisher判别分析结果,选用三维荧光光谱的第一主成分得分谱作为有毒赤潮藻识别特征谱,建立了有毒赤潮藻荧光特征库,在此基础上,利用非负最小二乘法对6种有毒赤潮藻进行识别测定,有毒赤潮藻的识别正确率≥80%。
The discrimination technology for 6 toxic species of the Red Tide algae was developed by in vivo 3D fluorescence spectra of the toxic algae and principle component analysis. Based on the results of Fisher linear discrimination, the first principle component score of 3D fluorescence spectra were chosen as discrimination feature and then the feature base was established. The 6 toxic algae species were tested by non-negative least square, more than 84% samples were accurately discriminated.
