邰晋, 龚绪龙, 梁莹, et al. 基于光谱指数和端元混合模型的滨海地下水溶解性有机质来源示踪[J]. Bulletin of Geological Science and Technology, 2025, 44(6): 237-248. DOI: 10.19509/j.cnki.dzkq.tb20230711.
滨海地下水中溶解性有机质(DOM)长期受到陆源、海洋源等多种有机质混合,定量评估其来源对认识滨海地区碳迁移转化具有重要意义。选取了江苏连云港市为研究区,利用同位素示踪和光谱指数识别了地下水DOM来源,并通过光谱指数与端元混合模型(EMMA)定量评估了不同端元对滨海地下水DOM的贡献占比。结果表明:滨海地下水DOM主要由河水DOM、海水DOM和沉积物可溶性有机质混合影响,3个端元贡献占比分别为44%±22%、33%±10%和22%±13%。研究区北侧地下水受到海水混入和淡水补给共同影响,地下水DOM具有较高海水DOM贡献占比和自生源特征;而研究区南侧.地下水咸化严重,高盐度地下水在径流过程中促进了沉积物可溶性有机质释放,地下水DOM具有较高的沉积物可溶性有机质贡献占比和腐殖化特征。研究成果为滨海地下水DOM来源的计算提供了评估方法。
