Zhejiang Daxue xuebao. Lixue ban, 2023 采用异位生态组合修复系统研究九龙江支流浦林溪污染水体不同形态磷净化效果及其对磷形态百分比的影响，并分析了异位生态组合修复系统各处理单元水体磷形态与环境因子的相关性。结果表明，异位生态组合修复系统对总磷（TP）、溶解态总磷（DTP）、可溶性正磷酸盐（DP）和颗粒态磷（PP）的平均总去除率分别为84.3%、84.4%、90.8%和78.9%，其中对DP净化效果最好。在异位生态组合修复系统各处理单元中，当原水水体中磷浓度较低时，泥膜共生高效混凝净水系统对TP、DTP和DP的净化效果良好，平均去除率分别可达81.

Shuitu Baochi Xuebao, 2022 为探究在全球气候变化敏感区的干旱区高寒湿地上,氮添加对土壤无机磷形态的影响。在保护良好的巴音布鲁克高寒湿地沼泽(S)、沼泽草甸(SM)和草甸(M)布设野外原位试验,依据巴音布鲁克草原氮沉降量,设置0(CK),8(N1),16(N2) kg·N/(hm2·a)的施氮量,研究短期氮添加对高寒湿地土壤无机磷形态的影响。结果表明:(1)高寒湿地土壤全磷含量平均为1.09 g/kg,总无机磷平均为492.71 mg/kg,而总无机磷平均占全磷的45.67%。(2)3种湿地类型土壤无机磷主要以Ca—P形态存在 ...

Shuitu Baochi Xuebao, 2001 对由向海湿地采集的土壤样品进行了无机磷酸盐形态 (吸附态磷、铝磷、铁磷、闭蓄态磷、钙磷 )分析 ,结果表明 ,钙磷是无机磷酸盐的主要组成部分 ,在各土壤发生层中含量最高 ;除吸附态磷外 ,其它各形态的磷含量总体上有随土壤深度增加而逐渐减少的趋势。铝磷、铁磷、闭蓄态磷受 p H值的影响显著 ,与 p H值呈显著负相关 ,而吸附态磷与钙磷含量则受 p H值的影响甚微。

Shuitu Baochi Xuebao, 2023 为探讨红壤侵蚀区不同植被类型下土壤磷素有效性,选取福建长汀红壤丘陵生态系统国家定位观测研究站的裸地(CK)、针叶林(CF)、针阔混交林(CB)以及阔叶林(BF)4种植被类型,分别测定其铁氧化物、各级磷素形态,并采用高通量测序技术对解磷菌(PSM)进行测定。结果表明:随着植被类型的转变,中等活性磷含量增加,低活性磷含量总体上减少,游离态氧化铁(Fed)含量逐渐减少。土壤中解磷菌的丰富度和多样性随植被类型的转变增加。在门分类水平上,优势类群主要有变形菌门(Proteobacteria)、放线菌门 ...

Functional Ecology, EarlyView.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.

Shuitu Baochi Xuebao, 2005 由于长期种植蔬菜，石灰性菜园土壤中的磷素在剖面中发生了分异，直接影响到其它营养元素的吸收和蔬菜的产量及品质。通过对不同植菜年限石灰性菜园土壤剖面磷素形态分级及其变异规律的研究，探讨了全磷、有效磷和无机磷不同形态的变异特征以及其磷素形态分布与其它土壤性质的关系。研究结果表明，石灰性菜园土壤耕层全磷、有效磷、无机磷与有机磷均比粮田富集强烈，有效磷源的无机磷形态含量与植菜年限呈明显的正相关，各形态无机磷含量的垂直分布与粮田存在显著关系，Ca2-P、Ca8-P、Fe-P含量为表层强烈富集，向下骤减的垂直分布特征。

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Constructing a porous scaffold with the essential features of natural cancellous bone, including structural architecture and biochemical cues, is one of the pivotal factors for effective bone regeneration. In this study, a biomimetic composite porous Gelatin fibrous scaffold (SrHA/Gelatin) incorporating ultralong strontium‐doped hydroxyapatite

Functional 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 ...

Plant nutrient‐acquisition strategies contribute to species replacement during primary succession
Journal of Ecology, Volume 113, Issue 4, Page 988-1003, April 2025.Pioneer species Hippophae acquires phosphorus and nitrogen mainly by ‘mining’ and N2‐fixing strategies and thus dominates in the beginning of primary succession. As soil nutrient availability increases with the mobilization of apatite‐P and input of N‐rich plant residues, Hippophae' strategies become less efficient than Populus's scavenging strategies.
