周村水库主库区水体热分层形成过程中沉积物间隙水DOM的光谱演变特征
|
摘要
运用三维荧光光谱(EEMs)技术结合平行因子分析法(PARAFAC)以及紫外-可见光谱技术,对周村水库热分层形成过程中沉积物间隙水中溶解性有机物(DOM)的垂向分布及光谱特性进行分析.结果表明:周村水库沉积物间隙水DOM的紫外-可见吸收光谱吸收系数的变异系数在-400%~400%之间,表明其性质在不同深度上存在差异; E2/E3变化说明随着热分层的形成,富里酸所占DOM的比例也随之升高; E3/E4> 3. 5以及SR> 1表明DOM为生物源,以富里酸为主;荧光光谱中出现了类富里酸峰(C1、C3)、类蛋白峰(C2、C5)和类腐殖酸峰(C4、C6);类富里酸以及类蛋白是DOM的主要构成组分; DOM总荧光强度、各组分荧光强度随着热分层形成过程呈下降趋势,垂向间和采样点的分布差异明显;热分层形成过程中水库沉积物间隙水的高BIX、FI、β:α以及低HIX,表明沉积物间隙水DOM以生物活动的内源为主,具有低腐殖化,强自生源特征.
Based on three-dimensional fluorescence spectra(EEMs) combined with parallel factor analysis(PARAFAC),and ultraviolet-visible(UV-Vis) spectra,we analyzed the vertical distribution and characteristics of dissolved organic matter in sediment interstitial water during the formation stage of thermal stratification in the Zhoucun Reservoir. The results show that the UV-Vis absorption coefficient varies between-400% and 400%,indicating the different properties of DOM(dissolved organic matter) at different depths. The changes of E2/E3 show that the proportion of fulvic acid in DOM increases with the stratification of the reservoir and fulvic acid accounts for the main proportion with autochthonous characteristics based on E3/E4 > 3. 5 and SR> 1. Two fulvic-like substances(C1,C3),two protein-like substance(C2,C5),and two humic-like substances(C4,C6) were identified with the PARAFAC model. Moreover,fulvic-like and protein-like substances account for most of substances. The total DOM fluorescence intensity and the fluorescence intensity of each component show a decreasing trend with the occurrence of stratification and exhibit significant vertical and temporal differences. Based on the analysis of FI,HIX,BIX,and β: α in sediment interstitial water,the high BIX,FI,β: α and low HIX indicate that the DOM of sediment interstitial water has strong autochthonous components and original characteristics of aquatic bacteria.
