1细数植物在人工湿地污水处理中的作用显示文摘天然的湿地植物在形态和解剖学上均能适应氧含量较低的生态环境,因此,它们可用于人工湿地系统中处理污水。而人工湿地中的植物不仅将人工湿地与稳定塘区分开,同时为污染物的去除创造适合的条件。人工湿地中的植物不仅能减弱强光与风力对湿地的影响,为湿地基质提供保温作用,满足根区微生物生长对氧气和其他营养成分的需求,还能截留部分污染物预防湿地堵塞,并具有其特有的美学价值,在不同类型的人工湿地中发挥不同程度的作用。最常见的人工湿地植物有漂浮植物如凤眼莲、浮萍;沉水植物如狐尾藻属、金鱼藻属;挺水植物如芦苇、香蒲属。而国内人工湿地除了以上这些常见植物外,还常用一些其他的沉水植物,比如芦竹、再力花、风车草以及美人蕉等。Jan Vymazal 卫婷 赵亚乾 Ulo Mander Florent Chazarenc 刘然彬 周敏伟 2021中国给水排水2021,37,2:11
2Global nitrogen input on wetland ecosystem:The driving mechanism of soil labile carbon and nitrogen on greenhouse gas emissions显示文摘Greenhouse gas emissions from wetlands are significantly promoted by global nitrogen input for changing the rate of soil carbon and nitrogen cycling,and are substantially affected by soil labile carbon and nitrogen conversely.However,the driving mechanism by which soil labile carbon and nitrogen affect greenhouse gas emissions from wetland ecosystems under global nitrogen input is not well understood.Working out the driving factor of nitrogen input on greenhouse gas emissions from wetlands is critical to reducing global warming from nitrogen input.Thus,we synthesized 72 published studies(2144 paired observations)of greenhouse gas fluxes and soil labile compounds of carbon and nitrogen(ammonium,nitrate,dissolved organic carbon,soil microbial biomass nitrogen and carbon),to understand the effects of labile carbon and nitrogen on greenhouse gas emissions under global nitrogen input.Across the data set,nitrogen input significantly promoted carbon dioxide,methane and nitrous oxide emissions from wetlands.In particular,at lower nitrogen rates(<100 kg ha^(-1)$·yr^(-1))and with added ammonium compounds,freshwater wetland significantly promoted carbon dioxide and methane emissions.Peatland was the largest nitrous oxide source under these conditions.This meta-analysis also revealed that nitrogen input stimulated dissolved organic carbon,ammonium,nitrate,microbial biomass carbon and microbial biomass nitrogen accumulation in the wetland ecosystem.The variation-partitioning analysis and structural equation model were used to analyze the relationship between the greenhouse gas and labile carbon and nitrogen further.These results revealed that dissolved organic carbon(DOC)is the primary factor driving greenhouse gas emission from wetlands under global nitrogen input,whereas microbial biomass carbon(MBC)more directly affects greenhouse gas emission than other labile carbon and nitrogen.Mengli Chen Lian Chang Junmao Zhang Fucheng Guo Jan Vymazal Qiang He Yi Chen 2020Environmental Science and Ecotechnology2020,,4:2
