荧光光谱具有灵敏度高、选择性好、分析速度快等特点被广泛应用于溢油鉴别。通过结合同步荧光光谱法、导数荧光光谱法和三维荧光光谱法对某码头一次溢油事故的溢油样进行分析鉴别，快速准确地鉴别出溢油源，进一步说明了荧光光谱法是溢油鉴别中一种有效的技术方法。研究结果表明：(1)同步荧光光谱对油源较为相近的油样区分能力较差，但可初步判断其相似性；(2)三维荧光光谱图油样荧光强度会受风化等因素的影响，但谱图的整体轮廓受干扰因素影响较小，芳烃的测定结果能比较准确地反映出溢油源的特征信息；(3)一阶导数荧光光谱中峰的比值能增强光谱特征，提高溢油鉴别的分辨能力。

With the characteristics of high sensitivity, good selectivity and high speed in analysis, fluorescence spectra have been widely used in the identification of oil spill. By combining the synchronous fluorescence spectrometry, derivative spectra and three-dimensional fluorescence spectrometry, this paper analyzes and identifies the spilled oil samples from a harbor. The source of spilled oil is reliably and quickly distinguished, which further illustrates the effectiveness of the fluorescence spectra used in oil spill identification. The study suggests that the synchronous fluorescence spectrometry has poor ability in identifying spilled oil samples with similar origins, while it can preliminarily estimate the similarities. For the three-dimensional fluorescence spectrometry, the generated fluorescence intensities of spilled oil samples are susceptible to a series of factors like weathering. Nevertheless, the overall outline of the map is less affected by interference factors, and the measured results of arenas can accurately reflect the characteristics of the source of spilled oil. As to derivative spectra, the ratio of middle speak can strengthen the spectrum characteristics and enhance the resolving power of the oil spill.
