摘要：

解析夏季洞庭湖不同湖区溶解性有机质（DOM）的来源、荧光特征及环境行为对湖泊水体污染来源监测、水环境污染防治及安全调水具有十分重要的意义。利用DOM Fluor工具运行平行因子分析模型（PARAFAC）与同步荧光光谱（SFS）和紫外荧光光谱（UV-Vis）结合探究夏季洞庭湖水体DOM来源及荧光特性。水体中DOM一共含有4类荧光组分：C1、C2（类富里酸）,C3（类蛋白）,C4（类胡敏酸）。其中,洞庭湖DOM以类富里酸物质（C1、C2）为主。地统计分析结合荧光光谱指数（FI、BIX、HIX）分析结果表明,洞庭湖水体DOM主要以内源输入为主,受结构性因素影响较为强烈,洞庭湖4类组分均为极显著正相关（P<0.01）,说明洞庭湖东、南、西3个湖区联系密切,各湖区水体DOM具有较高同源性。东、南、西3个湖区的荧光组分与各水质参数的相关分析结果不尽相同,东洞庭湖水体DOM中较高的类腐殖质和类蛋白物质与丰水期干流水系、自然条件及周围人类活动息息相关。

Abstract:

Analyses of the sources, fluorescence characteristics and environmental behavior for the dissolved organic matter (DOM) in different regions of Dongting Lake in summer season are of vital significance to the pollution sources detections, water pollution preventions and water transportation safety. A combined approach of parallel factor analysis (PARAFAC), synchronous fluorescence spectroscopy (SF) and ultraviolet fluorescence spectroscopy (UV—Vis) was employed to elucidate sources and fluorescence characteristics of DOM in Dongting Lake in summer. A total of 4 fluorescence components, including fulvic-like components C1 and C2, protein-like component C3 and humic-like component C4 were obtained by PARAFAC and the DOM in Dongting Lake was dominated by fulvic-like substances (C1 and C2). As indicated by geostatistical analysis, the DOM concentration in Dongting Lake was mainly affected by structural factors. Results of absorption parameters (A₂₅₀/A₃₆₅, a₂₅₄, A_SUV, A_SUV-260) combined with fluorescence spectral index (FI, BIX and HIX) showed that DOM in Dongting Lake was mainly derived from endogenous inputs, and differences for the correlation analysis between fluorescence components and water quality parameters existed between the East, South and West Dongting Lake. Correlation analysis showed a significant correlation among four components in Dongting Lake (P<0.01), which indicated that the sources of DOM were similar from the East, South and West Dongting Lake. The relatively high humic and protein-like substances in the DOM of the East Dongting Lake may be related to the main-stream system during the wet season, the natural conditions and the surrounding human activities.

Key words: dissolved organic matter (DOM), parallel factor analysis model, ultraviolet-visible absorption spectrum, spectral characteristics, Dongting Lake
