临江河水体溶解性有机质荧光光谱特征解析
Analysis of the fluorescence spectral characteristics of dissolved organic matter in the Linjiang River watershed
摘要
Abstract
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 protein-like 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.关键词
