中文摘要	以鄂尔多斯地区的小叶杨( Populus simonii) 、沙蒿( Artemisia desertorum)和沙柳( Salix psammophila)以及豫中平原地区的毛白杨( Populus tomentosa)植物落叶提取的溶解性有机质( Dissolved Organic Matter, DOM)为研究对象,通过对DOM理化指标的测试,结合紫外-可见和三维荧光光谱技术,对DOM中的有机物结构特征和含量关系进行了对比研究。研究结果表明:四种植物DOM中DOC和COD显著相关( r~2 = 0. 96) ,且DOC、COD、富里酸及腐殖酸的荧光峰强均与pH呈现较好的线性负相关关系。单位有机碳总荧光峰强可以用来较好地指示植物DOM含量。对于在干旱地区的植物落叶DOM中芳香族蛋白类有机物含量均明显高于毛白杨,并且沙柳DOM中含有羰基和共轭羰基的官能团,而毛白杨的荧光类有机质则以腐殖酸类物质为主,其总荧光峰强要明显低于其他三种植物。土壤等因素的区域性差异对植物的盐分含量有很大影响。
英文摘要	Batch experiments were carried out to compare the structure and content of dissolved organic matter ( DOM) extracted from the fallen leaves of Populus simonii,Artemisia desertorum and Salix psammophila in Ordos City and the Populus tomentosa in Zhengzhou City. During the experiments,the dissolved organic carbon ( DOC) ,chemical oxygen demand ( COD) ,pH,electrical conductivity ( EC) ,UV-Vis absorbance and 3D fluorescence spectra were measured for the DOM samples. The results showed that there was a significant correlation between DOC and COD for the DOM samples ( r~2 = 0. 96) . Meanwhile,pH had an obvious linear negative correlation with DOC,COD and the fluorescence peak intensity of fulvic acid and humic acid individually. The fluorescence intensity ( divided by DOC) including all peaks could be used to quantify the DOM content of the studied plants. The contents of aromatic protein for the DOM samples from Ordos City were significantly higher than that of the Populus tomentosa from Zhengzhou City. Additionally,DOM of Salix psammophila contained functional groups of carbonyl and conjugated carbonyl. The humic acid was the major fluorescence component in the DOM extracted from the Populus tomentosa. And its fluorescence intensity of all peaks was significantly lower than that of the other three plants. In general,regional differences in soil components had a great influence on salt content of the studied DOM.
