摘要
湿地作为一个特殊的生态系统,在维持生物多样性、调蓄洪水、降解污染物、调节气候等方面发挥着重要作用。总结概括了当前湿地生态系统中有关地球化学研究的现状,包括湿地生态系统中的持久性有机污染物(POPs)和重金属研究及人为影响,生命元素碳、氮、磷的研究及环境意义,湿地系统的稳定同位素研究3个方面。
As particular ecosystems, wetlands play an important role in maintaining biologic diversity, storing flood, degrading pollutants, and regulating climatic conditions. The authors summarize present situations of researches on geochemistry of wetland ecosystems, in the aspects of persistent organic pollutants (POPs), heavy metals and man-made effects as well as carbon, nitrogen and phosphorus and their environmental implications, and stable isotopes in the wetland ecosystems.
