摘要:
利用紫外可见光谱、三维荧光光谱研究乌鲁木齐夏季降水、冬季降雪中溶解性有机质(DOM)光谱特征,运用后向轨迹模型对DOM来源进行解析。紫外可见光谱分析结果表明,冬季降雪样品中的DOM分子量相对较低,夏季降水样品中DOM胡敏酸的含量比富里酸含量大,冬季降雪样品中相反;夏季降水样品中腐殖化程度低于冬季降雪,冬季样品中DOM的有机物分子缩合程度较低。三维荧光光谱分析结果表明,样品中DOM主要由生物活动产生,腐殖化程度较弱,类腐殖质和类蛋白质贡献均有,DOM来源既有陆源输入,也受到微生物活动的影响,腐殖组分发育程度较低。后向轨迹模型分析结果表明,不同高度乌鲁木齐夏季降水来源基本相同,主要来自西西伯利亚长距离传输和哈萨克斯坦楚河—萨雷苏盆地长距离传输。降雪100 m处的气流主要来自准格尔盆地短距离传输,500、1 000 m处的气流主要来自西西伯利亚长距离传输和天山山脉中段距离传输。
