中文摘要
翻译
河岸湿地被认为是重要的地形,可以有效地减少农业用地的化学品负荷,但地下水和地表水中的硝酸盐负荷仍然是一个问题。这在五大湖地区尤为明显,那里的湖泊继续受到农业做法的影响。需要更好地了解河岸湿地何时以及为什么不能减少硝酸盐,特别是在五大湖地区,那里存在气候变化增加的威胁。
英文摘要
Riparian wetlands have been identified as important landforms that effectively reduce the loading of chemicals from agricultural lands, yet nitrate loading in ground water and surface water remains a problem. This is particularly evident in the Great Lakes Region, where the lakes continue to be impacted by agricultural practices. An improved understanding of when and why riparian wetlands do not attenuate nitrate is needed, particularly in the Great Lakes region, where the threat of increased climatic variability exists.
