摘要/Abstract

摘要： 利用三维荧光光谱（3DEEM）和平行因子分析法（PARAFAC）研究巢湖湖滨带沉积物间隙水中溶解性有机质（DOM）含量组成、剖面分布特征及主要来源。结果表明，间隙水中DOM含有3种荧光组分，包括类腐殖质组分C1（275 nm，365 nm/467 nm）、类腐殖质组分C2（330 nm/407 nm）和类酪氨酸组分C3（275 nm/319 nm）。在空间分布上，远岸带DOM总荧光强度均值为（0.432±0.306）RU，低于近岸带DOM总荧光强度均值〔（0.583±0.478）RU〕，同时近岸带荧光强度均值大于湖心点，各点位垂直剖面上荧光强度随沉积物深度呈现下降趋势；在时间分布上，沉积物间隙水夏季DOM总荧光强度均值为（0.390±0.301）RU，小于冬季〔（0.584±0.453）RU〕；此外，近岸带DOC浓度高于远岸带，远岸带DOC浓度高于湖心点，冬季各断面DOC浓度高于夏季；随着沉积物深度的增加，DOC浓度首先呈现升高趋势后迅速随深度增加而降低，在底泥界面10 cm以下保持稳定状态；冬季腐殖化指数（HIX）高于夏季，荧光指数（FI）和生物源指数（BIX）表明沉积物间隙水DOM受到内源中生物源与外源污染中陆源的共同影响，受到内源中生物源影响更大。该研究可为巢湖湖滨带水环境管理与面源污染控制提供一定参考。

Abstract: Three-dimensional fluorescence spectroscopy (3DEEM) and parallel factor analysis (PARAFAC) were used to study the composition, profile distribution characteristics and main sources of dissolved organic matter (DOM) in the interstitial water of sediments in the littoral zone of Lake Chaohu. The results show that DOM in interstitial water contained three fluorescent fractions, including humic-like fraction C1 (275 nm, 365 nm/467 nm), humic-like fraction C2 (330 nm/407 nm) and tyrosine-like fraction C3 (275 nm/319 nm). In terms of spatial pattern, the mean value of DOM fluorescence intensity in the pelagic zone was (0.432±0.306) RU, which was lower than the mean value of DOM fluorescence intensity in the near shore zone of (0.583±0.478) RU, while the mean value of fluorescence intensity in the near shore zone was greater than that in the center of the lake, and the fluorescence intensity showed a decreasing trend with depth in the vertical profile at each point. In terms of time pattern, the mean value of DOM fluorescence intensity in summer was (0.390 0±0.301) RU, less than that in winter[(0.584±0.453) RU];In addition, the DOC concentration in the nearshore zone was higher than that in the pelagic zone, the DOC concentration in the pelagic zone was higher than that in the lake center, and the DOC concentration in all sections in winter was higher than that in summer; The DOC concentration first increased, then decreased rapidly with the increase of sediment depth, and remained stable below 10 cm layer of sediment-water interface. The humification index (HIX) in winter was higher than that in summer, and the fluorescence index (FI) and biogenic index (BIX) indicated that DOM in interstitial water was influenced by both endogenous biogenic sources and terrestrial sources of exogenous pollution, and was more influenced by endogenous biogenic sources. This study can provide certain references for the water environment management and non-point source pollution control in the littoral zone of Lake Chaohu.
