Alleviation of phosphorus rather than nitrogen limitation driven by permafrost and landscape effects on Dahurian larch forests

open access: yesFunctional Ecology, Volume 40, Issue 8, Page 2590-2601, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Permafrost thaw is reshaping nutrient dynamics in boreal forests, but its impacts on tree nutrient limitation and functional strategies remain poorly understood. Clarifying these responses is crucial for predicting the response of boreal forests to climate change.

不同基质去除水中氮、磷的作用机理及效应

open access: yesShuitu Baochi Xuebao, 2011
对粉煤灰、矾土、活性炭、蛭石和火烧石5种基质的元素含量和表面化学性状进行了研究,并比较了这5种基质对P和NH4+-N的吸附性能。结果表明:粉煤灰呈碱性,具有较高的Fe、Ca含量,胶体氧化铁和水溶性Ca含量也最高,矾土呈酸性,Al含量和游离氧化铝含量最高,蛭石和火烧石呈中性,其中蛭石含有21.6%的Mg,活性炭比表面积最大。Langmuir等温吸附曲线方程能够对上述基质的P、NH4+-N吸附过程进行了很好的拟合,其中P理论饱和吸附量由大到小依次为粉煤灰>矾土>火烧石>活性炭>蛭石,NH4 ...

Pinus armandii ectomycorrhizas mobilize aluminium‐bound phosphorus via carboxylates along a subtropical altitudinal gradient

open access: yesJournal of Ecology, Volume 114, Issue 8, August 2026.
Ectomycorrhizal roots of Pinus armandii release more carboxylates than non‐mycorrhizal root segments, mobilizing Al‐bound inorganic P. Under the lowest available P conditions, they also secrete more phosphatase, promoting the mineralization of Al‐bound organic P.

稻秸还田对稻麦两熟农田麦季养分径流流失的影响

open access: yesShuitu Baochi Xuebao, 2011
采用田间小区定位试验研究自然降雨条件下稻秸全量还田对稻麦两熟农田麦季养分径流流失特征的影响。结果表明:麦季径流水量可达2 185.05 m3/hm2,秸秆还田(T1)处理可降低径流水量4.43%(p>0.05);常规施肥(T0)条件下,每1 hm2麦田径流流失全N(TN)和全P(TP)总量分别为30.90,3.00 kg,流失率分别达13.73%和3.34%;较T0处理而言,T1、T2(秸秆还田减肥)处理不仅减少TN和TP流失量分别达15.95%,33.50%和13.98%,15.71 ...

菹草对水体悬浮泥沙及氮、磷污染物的净化

open access: yesShuitu Baochi Xuebao, 2007
利用冬春季沉水植物菹草构建的阶梯式水生植物系统研究了其对水体悬浮泥沙及氮、磷污染物的净化效果。结果表明:由菹草构成的生态物理模型系统对挟沙水体氮、磷负荷以及泥沙含量具有较好的改善作用,菹草系统前后总氮负荷分别为0.746 mg/L和0.622 mg/L,去除率为16.57%,其中菹草净化率占6.67%;停留时间分别为24 h和48 h时,菹草系统对总磷的净化百分率分别为18.52%和22.22%,其中菹草对总磷的净化作用分别占10.83%和6.84%,因此,菹草系统对挟沙水体中氮、磷的净化 ...

Directed Construction of a Synergistic Li3P‐LiF Inorganic Solid Electrolyte Interphase Toward Stable Silicon Anodes

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Silicon–carbon composite anodes offer exceptionally high energy density, but their practical application is severely constrained by the structural instability and continuous evolution of the solid electrolyte interphase (SEI). In this work, moving beyond conventional LiF‐enrichment strategies, we propose a directional regulation approach based

铁镁铝三元类水滑石对磷的吸附特性研究

open access: yesGongye shui chuli, 2015
采用低饱和共沉淀的方法合成了n(Fe):n(Mg):n(Al)=1:1:1的铁镁铝三元类水滑石。研究其对磷的吸附特性,考察了吸附时间、投加量、温度、pH等因素对吸附效果的影响。结果表明:此类水滑石对磷的吸附在前20 min吸附量急剧增加,40 min之后趋于稳定;当投加量为1.0 g/L时,吸附率和吸附容量都相对较高;初始pH为3~10时,对吸附效果无明显影响;温度对吸附效果影响较大,温度升高吸附量增加,表明此吸附过程是吸热过程。此类水滑石对磷的等温吸附数据与Langmuir方程的相关系数很高,45 ...

改性磁铁矿的制备及其对水中磷的吸附

open access: yesGongye shui chuli, 2017
用硝酸钙和氯化镧对磁铁矿进行改性,考察不同初始浓度、pH、作用时间对含磷废水的吸附效果,进而分析其吸附等温线及动力学特性。结果表明:Langmuir等温吸附方程能很好地描述其等温吸附特性,未改性、硝酸钙改性、氯化镧改性的磁铁矿对磷的吸附饱和量分别为0.068、0.409、2.157 mg/g;未改性、硝酸钙改性、氯化镧改性的磁铁矿分别在pH为12、pH为8~12、pH为4~10时,对磷的吸附效果较好;氯化镧改性磁铁矿对磷的去除率达95%以上且其吸附过程符合二级吸附动力学方程。
