摘要

通过对兴凯湖长期N、P添加平台设置不同浓度的处理,分析DOM的浓度和光谱学特征,来探究外源N、P及其交互效应对泥炭地DOM结构复杂性的影响.研究结果表明,外源N、P输入没有显著改变DOM的浓度,但DOM的芳香化程度在高氮(N₍₂₎)、低磷(P₍₁₎)以及NP交互效应下显著提高了58.5%~82.9%.此外,高磷(P₍₂₎)和低氮高磷(N₍₁₎P₍₂₎)处理增加了DOM的内源输入.DOM的荧光组分主要以类腐殖质物质和类蛋白质物质为主,单独N、P处理提高了类蛋白质含量,而NP交互效应增加了类腐殖质含量.这些结果表明外源N、P输入会通过刺激植物生长以及促进微生物活性来增加DOM的结构复杂性.

Abstract

This study investigated the impact of exogenous N and P additions and their interactions on DOM, focusing on its concentrations and structural complexity by analyzing their spectroscopic characteristics in the long-term N, P additions platform in the boreal peatlands. The results indicated that exogenous N and P additions did not significantly alter DOM concentration, but a significant increase in DOM aromatization, from 58.5% to 82.9%, under high nitrogen (N₍₂₎), low phosphorus (P₍₁₎), and combined N-P treatments. Additionally, the endogenous input of DOM was amplified in treatments with high phosphorus (P₍₂₎) and low nitrogen combined with high phosphorus (N₍₁₎P₍₂₎). Fluorescence analysis indicated that DOM primarily consisted of humic-like and protein-like substances. Individual N or P treatments were found to enhance the content of protein-like substances, whereas NP interactions predominantly increased the humic-like content. These results suggest that exogenous N and P additions increase the structural complexity of DOM by promoting plant growth and enhancing microbial activity in boreal peatlands.
