摘　　要：为探究临江河水体溶解性有机质荧光光谱特征、组成及来源,本研究利用三维荧光光谱结合平行因子分析的方法对临江河水体溶解性有机质荧光光谱特征、荧光组分、水质指标及它们之间的相关性进行分析。结果表明:临江河流域森林山区水体存在典型类腐殖峰A及类富里酸峰C,村镇水体及农田水体除了存在典型类腐殖峰还出现类蛋白峰,养殖区水体存在典型类蛋白峰B和T。平行因子分析解析出2类3个荧光组分,分别为类腐殖质荧光组分C1、C2,类蛋白荧光组分C3。研究表明,三维荧光特征参数揭示出临江河水体溶解性有机质受到内外源的共同影响,相关性分析表明临江河水体中荧光组分及特征与氮、磷等元素的迁移转化密切相关。This study aimed to explore the fluorescence spectrum characteristics,composition,and source of dissolved organic matter(DOM)in Linjiang River water.This study employed three-dimensional fluorescence spectroscopy combined with parallel factor analysis to analyze the fluorescence spectral characteristics,fluorescence components,water quality indicators,and their correlations with DOM in the Lijiang River.The results indicated that water in the forested mountainous area of the Linjiang River basin exhibited typical humic-like peak A and fulvic-like peak C,while water in villages and farmland showed the presence of both a typical humic-like peak and proteinlike peak,and water in aquaculture areas exhibited typical protein-like peaks B and T.Parallel factor analysis revealed two categories of three fluorescence components,namely humic-like fluorescence components C1 and C2,and protein-like fluorescence component C3.This study demonstrated that the three-dimensional fluorescence characteristic parameters revealed the combined influence of both internal and external sources on DOM in Linjiang River water.Correlation analysis indicated a strong relationship between fluorescence components,characteristics,and the migration and transformation of elements such as nitrogen and phosphorus in Linjiang River water.
