摘要针对莫莫格自然保护区,选择3个水体,利用三维荧光光谱结合平行因子分析(PARAFAC)探究溶解性有机质(DOM)的组成、光谱特征和来源;采用二维相关光谱结合结构方程模型分析DOM组分变化及其与水质指标的响应关系.结果表明,水体DOM受内源和外源共同作用,腐殖化特征明显,蛋白质组分含量较低.PARAFAC共识别出微生物代谢产物(C1)、类富里酸(C2和C4)、类胡敏酸(C3)和类色氨酸(C5)等5种组分,其中C1组分含量最高(41.37%);DOM来源、组成、转化与保护区内水生动、植物生长环境下的微生物代谢过程紧密相关,采用2D-COS表征沿水流方向DOM组分的变化顺序为:C4→C2→C3→C1→C5,类富里酸(C2和C4)含量的变化幅度大于类色氨酸,类色氨酸的含量相对比较稳定.C1、C5组分与COD_Mn呈显著正相关,表明其具有同源性,主要来源于藻类生长死亡过程中产生的大量有机物.DOM来源和组成对水环境因子有直接或间接的影响,DOM主要通过腐殖化程度直接影响水质状态,影响权重为46.17%;DOM组分C2和C3间接影响水质状态,影响权重为17.59%.莫莫格自然保护区水体DOM组成与水环境因子响应机制的研究,可为自然保护区水生态保护提供理论依据.

Abstract：In Momoge Nature Reserve, three distinct water bodies were selected for the investigation of the composition, spectral characteristics, and sources of dissolved organic matter (DOM) utilizing three-dimensional excitation emission matrix spectroscopy in conjunction with parallel factor analysis (PARAFAC). Additionally, two-dimensional correlation spectroscopy combined with structural equation modeling was employed to analyze the variations of DOM components and their relationships with water quality parameters. The results indicated that the DOM in the water bodies originated from both endogenous and exogenous sources, which has obvious humification characteristics. Five components were identified as microbial metabolites (C1), fulvic acid-like (C2 and C4), humic acid-like (C3) and tryptophan-like (C5) through three-dimensional fluorescence coupled with PARAFAC. Of five components, C1content was the highest (41.37%). The changing sequence of DOM components along the direction of water flow was characterized by 2D-COS as follows: C4→C2→C3→C1→C5, with humic-like substances showing greater variation than tryptophan-like substances, and the content of tryptophan-like substances being relatively stable. The humification degree of DOM directly affected the water quality status with influence weight of 46.17%. The water quality was indirectly impacted by DOM components C2 and C3 with a 17.59% influence weight. Insight into the response mechanism of DOM properties to water quality in Momoge Nature Reserve could provide a theoretical basis for the ecological protection of nature reserves.
