2018年研究院团队成员苏芳莉教授等在期刊“Environmental Monitoring and Assessment volume”上发表题目为“The distribution and enrichment characteristics of copper in soil and Phragmites australis of Liao River estuary wetland”的论文，研究深入探讨了位于辽河口湿地的土壤和芦苇植物中铜元素的分布和积累特征。研究内容包括了铜元素在湿地土壤中的分布模式，以及其在芦苇植物体内的积聚情况。通过详尽分析这些特性，研究不仅揭示了铜在土壤和植物中积聚的机制，还详述了可能影响其积聚的因素，如土壤性质和植物生长状态等。同时，对铜元素在生态系统和环境中积聚所带来的潜在风险进行了详细研究，并探讨了植物与土壤中铜含量与生态系统稳定性之间的联系。该研究为辽河口湿地生态系统的保护和管理提供了有力的科学支持，为相关环境政策和措施的制定提供了有益参考，对于深入理解铜元素在湿地生态系统中的行为及其对环境的影响，具有显著的重要意义，有助于揭示湿地生态系统中的生物地球化学过程，为湿地环境的可持续管理与保护提供了坚实的理论基础。
Abstract The aims of the present investigation were to reveal the distribution and enrichment characteristics of copper in soil and Phragmites australis of Liao River estuary wetland. The concentrations of copper in root, stem, leaf, and ear of Phragmites australis as well as in soil were determined to study the absorption capacity of copper by wild Phragmites australis of Liao River estu- ary wetland. The study was carried out at test pool of the Shenyang Agricultural University, and the experimental materials (soil, irrigating water and Phragmites australis) were derived from Liao River estuary wetland. The con- centrations of copper in soil and Phragmites australis were 16.4441 to 49.0209 mg/kg and 0.8621 to 89.5524 mg/kg, respectively. The results indicated that the enrichment coefficients of copper in different tissues of Phragmites australis changed with the growth of Phragmites australis. The results revealed that the enrichment coefficients of copper in the whole Phragmi- tes australis were greater than 1 at each growing stage of the Phragmites australis. The results also showed that the transfer coefficients of Phragmites australis to copper changed with the growth of Phragmites australis. The results revealed that the Phragmites australis had a good removal effect on copper from soil and had some char- acteristics of copper hyperaccumulator.
