| 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（UV-vis），对周村水库季节演替过程中沉积物上覆水溶解性有机物（DOM）的紫外-可见以及三维荧光光谱特征进行分析.结果表明：周村水库上覆水的总氮、溶解性总氮、总有机碳和溶解性有机碳的季节性差异显著，并且冬季总氮浓度最高、夏秋季总有机碳浓度较高；夏秋季上覆水DOM的吸收系数a254和a355均高于冬春季，与有机物的分布相一致；4个季节上覆水DOM的E3/E4均大于3.5，说明DOM以富里酸为主，E2/E3（富里酸占DOM的比例）在夏秋季低于冬春季，而且各季节SR均大于1，表明DOM主要为生物源；三维荧光通过PARAFAC解析出3种组分：类腐殖质（C1）、可见区富里酸（C2）和类蛋白（C3）；对3个组分进行相关性分析，结果显示C1、C2、C3之间具有显著的相关性；DOM的总荧光强度以及各组分的荧光强度均呈现出夏秋季高、冬春季低的特征，且各季节间差异显著；周村水库4个季节的DOM生物源指数（BIX）在0.8~1.0之间，表明水库DOM具有较强的自生源特征，与腐殖程度指标（HIX）的结果相吻合；主成分分析显示周村水库上覆水DOM的光谱特征差异明显，夏秋季的DOM光谱特征相近、冬春季的水体DOM特征相似；并且组分C1、C2、C3与DOM特征参数（a254、SUVA280、HIX、FI、BIX）以及溶解性有机碳呈显著相关.各荧光组分与水质参数（溶解性总氮和溶解性有机碳）的多元线性回归呈现很好的拟合，通过建立回归方程可以为以后研究周村水库水体四季的DOM光谱特征，分析水库水体的有机物污染特征，并为水库水质管理提供技术支持.
