Conservation Biology, Volume 37, Issue 1, February 2023., 2023 Abstract Insights into declines in ecosystem resilience and their causes and effects can inform preemptive action to avoid ecosystem collapse and loss of biodiversity, ecosystem services, and human well‐being. Empirical studies of ecosystem collapse are rare and hampered by ecosystem complexity, nonlinear and lagged responses, and interactions across ...

Rewilding in the face of climate change
Conservation Biology, Volume 35, Issue 1, Page 155-167, February 2021., 2021 Abstract Expansion of the global protected‐area network has been proposed as a strategy to address threats from accelerating climate change and species extinction. A key step in increasing the effectiveness of such expansion is understanding how novel threats to biodiversity from climate change alter concepts such as rewilding, which have underpinned ...

Effects of Biochar Application on Nitrogen and Phosphorus Availability in Soils: aReview [PDF]
, 2016 利用生物炭在贫瘠的土壤上培育出肥沃的"黑土"正成为土壤学家研究的热点.氮、磷等大量养分是衡量土壤肥力高低的重要指标,生物炭对其有效性影响表现出极大的复杂性.不同研究得出的结论不尽相同,关键是缺乏对其机制的深入研究.由于氮和磷的不合理利用还可能造成非点源污染而带来环境风险,再加之生物炭施用的不可逆性,必须确保生物炭在任何情况下都不会对土壤和环境带来不利的影响.为此,本文综述了生物炭添加对氮肥和磷肥在土壤-植物系统迁移转化过程中的作用,重点讨论了不同生物炭处理方式对土壤磷素吸附解吸和形态转化的影响 ...

Shuitu Baochi Xuebao, 2023 生物炭的性质与老化作用是影响生物炭钝化修复Cd污染土壤效果的重要因素。比较研究4种不同原料生物炭(污泥类、秸秆类、动禽粪便类和木本类)对Cd2+吸附作用和Cd污染土壤的钝化修复效果的差异。结果表明:施用生物炭显著提升土壤孔隙水pH(棕榈丝生物炭除外),降低孔隙水DOC和Cd浓度,从而减少水稻根系对孔隙水中Cd的吸收。同时,4种生物炭提高土壤pH,降低土壤有效态Cd、水稻根系和籽粒Cd含量。老化作用减弱稻秆生物炭的钝化效果,显著增强棕榈丝生物炭对土壤Cd的钝化作用,然而 ...

Preparation of Biochar from Different Biomasses and Their Application in the Li-S Battery [PDF]
, 2017 通过可再生生物质制备的生物炭具有成本低、环保和资源可再生的优势。本研究以分布广泛的稻谷壳、芒草、杉木和柚子皮等生物质为原料,制备了4种不同类型生; 物炭,然后研究了其作为锂-硫电池硫/碳正极的载体的性能。研究表明由稻谷壳制备的硫/生物炭正极材料表现出最高的比容量和最优的循环稳定性。为了进一步; 改善其电性能,以SiO_2溶胶为模板制备了具有高孔隙率的稻谷壳生物炭,其多孔结构可有效抑制多硫化物的溶解。由此得到的硫/生物炭(硫含量为60%; (w,质量分数))材料中的硫以无定型态均匀地分散在碳载体中 ...

Shuitu Baochi Xuebao, 2022 通过控制不同生物炭添加量和降水量,分析土壤理化性质及黑麦草(Lolium perenne L.)的各项生长指标,探究不同添加量的生物炭对缺水植物生长促进的直接与间接作用。结果表明:生物炭的添加可以提高土壤的田间持水率、土壤中速效磷的含量以及土壤的pH;干旱条件下,增加生物炭的用量能促进黑麦草植株的增高,但高剂量的生物炭抑制黑麦草的生长;生物炭加入并不能持续性的保持土壤中的水分,高浓度(>15%)的生物炭反而增大土壤中水分的流失,但由于生物炭中钾元素为植物对抗干旱提供了必要条件。适当添加生物炭(5 ...
