Research on Ammonia Emission Inventory in Fujian Province [PDF]

open access: yes, 2016
近年来,随着福建地区经济快速发展,城市化进度不断加快,环境与经济发展的矛盾日益突出,大气灰霾污染频繁发生,空气质量和能见度下降。氨是大气霾污染生成的促进剂,对大气污染有着直接和间接的影响。本研究建立了福建省人为源氨排放清单,分析氨的排放特征和时空分布,预测未来氨排放水平,探讨氨排放与氨监测和颗粒物离子的关系,为该地区空气质量改善提供了重要的基础数据。 首先,本研究以2013年为基准年,基于排放因子法建立了福建省人为源氨排放清单。研究显示,2013年福建地区人为源氨总排放量是25.24万吨 ...

Fabricating Highly Efficient Ternary Mn–CeOx/Co3O4 Catalysts for Low Temperature Thermal Desorption of Persistent Perfluorooctanoic Acid in Soil

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Developing efficient catalytic thermal desorption systems is of great significance in the field of sustainable soil remediation. Herein, novel Mn–Ce solid solution modified Co3O4 nanocrystals were successfully prepared for the removal of perfluorooctanoic acid (PFOA) in soil.

Strategies in Ericaceae to acquire phosphorus in phosphorus‐impoverished habitats in the southwest Australian biodiversity hotspot

open access: yesFunctional Ecology, Volume 39, Issue 10, Page 2889-2904, October 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In the Southwest Australian Biodiversity Hotspot, the greatest plant species diversity tends to occur on the most phosphorus (P)‐impoverished soils. Many plant species in this P‐impoverished environment release root carboxylates that mobilise soil P which is a more ...

Study on Soil Acidity Reconstruction by Using Dendrochemistry in the Subalpine Forest Ecosystems of Western Sichuan [PDF]

open access: yes, 2011
酸沉降是全球面临的重大环境问题之一,已经造成了许多地区的环境破坏和生态恶化。为此,人们对酸雨的性质及环境效应进行了广泛的研究,已经有了越来越深刻的认识。而作为引起森林树种衰退和死亡的主要原因,由酸沉降导致的土壤酸化问题更是备受关注。在大多数地区,历史监测资料的缺乏却给长期土壤酸化的评估带来了很多的困难,但是树木年轮元素含量的径向变动提供了检测林区土壤化学历史变动的潜力,从而可以用来克服这一困难。 基于以上几点,本研究为获取重建川西亚高山森林生态系统土壤酸化历史变迁的最佳指标,选取该地区峨眉山(严重酸沉降)

Arbuscular mycorrhizal fungus reshapes the rhizosphere microbiome of alfalfa in response to above‐ground attack by aphids and a fungal plant pathogen

open access: yesFunctional Ecology, Volume 39, Issue 8, Page 2149-2169, August 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants assemble beneficial rhizosphere microbiomes through a ‘cry for help’ mechanism upon pathogen or insect herbivore attack. The arbuscular mycorrhizal fungi (AMF) can influence the composition of microbial communities in the plant rhizosphere. However, their impacts

钙质钝化材料对四川盆地6种主要旱作土壤Cd的钝化效应

open access: yesShuitu Baochi Xuebao, 2023
为针对性、定量化地利用钝化处理实现不同类型Cd污染土壤的安全利用,以四川盆地6种主要旱作土壤为研究对象,采用室内培养试验和土培试验探讨了6个剂量水平下,钙质钝化材料对土壤pH、CEC、有效Cd含量、Cd形态、小白菜生物量和Cd含量的影响。结果表明:(1)钙质钝化材料可提升6种土壤的pH和CEC,土壤CEC随用量的增加而持续增加,而土壤pH在提升至微碱性水平后,不再随用量的增加而增加;(2)6种土壤有效Cd含量随钝化材料用量的增加先显著降低,后趋于平稳,用量>2.5%后均无显著变化。该添加量下 ...

Plant–microbe interactions drive the rhizosphere microbial assembly and nitrogen cycling in a subtropical forest

open access: yesFunctional Ecology, Volume 39, Issue 5, Page 1274-1287, May 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Interactions between plants and soil microorganisms in the rhizosphere are vital for maintaining the nutrient cycle and stability of terrestrial ecosystems. Nitrogen, closely related to carbon (C) cycling and ecosystem productivity, undergoes transformation by soil ...

石灰性土壤磷素的化学活化途径探讨

open access: yesShuitu Baochi Xuebao, 2005
用草酸、草酸钠、柠檬酸和柠檬酸钠作为活化剂,加人不同含磷水平土壤中,通过室内培养试验和分析,结果表明:(1)0.1M草酸和0.1M柠檬酸都有一定的活化土壤磷素的作用,草酸作用最为显著。而相同浓度的草酸钠和柠檬酸钠未显示对土壤磷素的活化效果。(2)对土壤磷素的活化作用,草酸随其浓度的增加而增强,而柠檬酸活化土壤磷的能力有限。(3)柠檬酸在加人的6h之内,对活化土壤速效磷作用明显;而草酸在加人的48h之内,对活化土壤速效磷有十分显著的作用。无论是柠檬酸还是草酸,在其对土壤速效磷发挥活化作用期间 ...
