摘要

以荆江段高水动力砂质洲滩三八滩和缓流淤积黏土洲滩乌龟洲为对象,采用三维荧光光谱-平行因子分析(EEMs-PARAFAC)和连续提取法,解析SDOM组分特征与磷形态的响应机制.结果表明:三八滩与乌龟洲SDOM的组成特征差异显著,三八滩以类蛋白组分为主,其高生物活性特征与Fe/Al-P的高占比共同主导磷形态分布;而乌龟洲以类腐殖质组分为主导,其高芳香性与强络合能力促进有机磷累积,显著高于三八滩;类蛋白组分与Fe/Al-P呈显著负相关(P<0.05),腐殖化指数与有机磷呈显著正相关(P<0.05),表明SDOM主要通过与金属氧化物竞争吸附位点、改变微生物代谢两种途径影响磷的形态;三八滩的SDOM更容易与铁铝氧化物结合形成沉淀,从而截留更多Fe/Al-P,而乌龟洲中低分子量的类蛋白SDOM会加速有机磷的分解矿化.研究首次阐明长江中游洲滩SDOM对磷形态的影响,为大型河流水文调控磷截留功能提供理论依据.

Abstract

This study focused on the high-hydrodynamic sandy shoal Sanba Tan and the slow-flow sedimentary clay shoal Wugui Zhou in the Jingjiang section of the Yangtze River. The response mechanisms between the composition of SDOM and phosphorus forms were analyzed using EEMs-PARAFAC and sequential extraction methods. Significant compositional differences were observed between the SDOM from Sanbatan and Wuguizhou. Sanbatan was dominated by protein-like components, whose high biological activity, coupled with a high proportion of Fe/Al-P, was found to jointly govern the distribution of phosphorus forms. In contrast, the SDOM from Wuguizhou was primarily characterized by humic-like components, whose high aromaticity and strong chelating capacity were identified to promote the accumulation of organic phosphorus, which was significantly higher than that in Sanbatan. A significant negative correlation was observed between protein-like components and Fe/Al-P (P<0.05), while the humification index was significantly positively correlated with organic phosphorus (P<0.05). These results suggested that SDOM influences phosphorus forms through two primary pathways: competition with metal oxides for adsorption sites and alteration of microbial metabolism. At Sanba Tan, SDOM was more readily precipitated with iron-aluminum oxides, thereby retaining more Fe/Al-P. Conversely, the low-to-medium molecular weight protein-like SDOM in Wuguizhou accelerated the decomposition and mineralization of organic phosphorus. The influence of SDOM on phosphorus forms in sandbars of the mid-Yangtze River was elucidated for the first time in this study, providing theoretical support for the phosphorus trapping function associated with the hydrological regulation of large rivers.
