| 中文摘要 | Using excitation-emission matrix spectrum(EEMs) combined with parallel factor analysis(PARAFAC) examine the fluorescent components feature of dissolved organic matter (DOM) sampled from East China Sea in the summer and autumn was examined. The type, distribution and origin of the fluorescence dissolved organic matter were also discussed. Three fluorescent components were identified by PARAFAC, including protein-like component C1(235, 280/330), terrestrial or marine humic-like component C2(255, 330/400) and terrestrial humic-like component C3(275, 360/480). The good linearity of the two humic-like components showed the same source or some relationship between the chemical constitutions. As a whole, the level of the fluorescence intensity in coastal ocean was higher than that of the open ocean in different water layers in two seasons. The relationship of three components with chlorophyll-a and salinity showed the DOM in the study area is almost not influenced by the living algal matter, but the fresh water outflow of the Yangtze River might be the source of them in the Yangtze River estuary in Summer. From what has been discussed above, we can draw the conclusion that the application of EEM-PARAFAC modeling will exert a profound influence upon the research of the dissolved organic matter. |
