利用三维荧光光谱技术(EEMs)结合平行因子分析(PARAFAC)的方法,对2011年8月至9月胶州湾表层海水溶解有机物荧光特征的时间与空间变化进行了研究。PARAFAC 模型共鉴别出四个荧光组分：类蛋白质荧光组分(C1),陆源类腐殖质荧光组分(C2, C4)和海源类腐殖质荧光组分(C3)。类蛋白组分在调查期间的荧光强度最强(0.14±0.06),其余三个组分荧光强度相近(0.07±0.02,0.09±0.02,0.05±0.02)。这四种组分在8月下旬多雨期和9月上旬受径流影响的时期荧光强度较高,在9月下旬雨季影响消退后荧光强度显著降低。研究表明各组分荧光强度总体上与叶绿素 a 浓度显著正相关,与盐度负相关,说明胶州湾夏季FDOM浓度主要受降雨引发的生物活动影响。

Herein, the temporal and spatial variation of fluorescent characteristics of Dissolved Organic Matter in surface seawater in the Jiaozhou Bay, during August and September of 2011 was studied by using Excitation-Emission Matrix Spectrum (EEMs) combined with Parallel Factor Analysis (PARAFAC). Four fluorescent components including protein-like component (C1), terrestrial humic-like component (C2, C4) and marine humic-like component (C3) were identified by PARAFAC. The intensity of protein-like component was the highest (0.14±0.06), and the intensities of the other three components were close (0.07±0.02, 0.09±0.02 and 0.05±0.02) during the investigation. In late August and early Septem-ber, the intensities of four components were high, as influenced by rainfall and surface runoff, and then significantly de-creased in late September after rainfall. This study shows generally positive correlation between intensity of fluorescent components and chlorophyll a while negative correlation between intensity of fluorescent components and salinity. It shows that the concentration of FDOM in the Jiaozhou Bay was mainly influenced by biological activities caused by rainfall.
