| 摘 要： | 以秦岭北麓辋川河水体为研究对象,利用紫外可见吸收光谱、荧光光谱结合平行因子分析法解析了夏季辋川河水体有色溶解性有机质(CDOM)的组成结构,并探讨了水体有色溶解性有机质的来源,运用冗余分析法和Pearson相关性分析阐明了光学参数与水质参数的相关性.结果表明,①辋川河水体CDOM由类色氨酸组分C1(245, 300/335 nm)、短波类腐殖质组分C2(240, 320～340/405 nm)和长波类腐殖质组分C3(270, 350～370/470 nm)组成,其中组分C1与C2具有一定的同源性(r=0.859,P0.001).②CDOM吸收系数α(355)表明辋川河水体CDOM浓度处于较低水平,并且α(355)与DOC浓度相关性显著(r=0.850,P0.001),这有利于建立DOC反演模型.③水体荧光指数FI(2.36±0.20)、HIX(3.66±2.47)、BIX(1.56±0.82)和新鲜度指数(β:α)(1.33±0.62),以及光谱斜率比S_R(0.76±0.25)表明,辋川河水体CDOM呈现强自生源、低腐殖化和非陆源的特征.④冗余分析结果表明类腐殖质组分(C2、C3)受藻类代谢和微生物作用影响,而类色氨酸组分(C1)与陆源输入有关,类色氨酸组分C1与DTN呈负相关关系,类腐殖质组分C2和C3与TP、DTP和DOC呈现正相关关系.本文阐明了夏季秦岭北麓河流水体有色溶解有机质的特征及影响因素,为秦岭流域水体治理提供理论依据.
