Shuitu Baochi Xuebao, 2017 基于室内模拟培养试验，研究改良剂（生物质炭、过氧化钙）对旱地红壤微生物量碳、氮及可溶性有机碳、氮的影响。试验设置4个处理，即CK、Ca（过氧化钙，1.72 g/kg）、C（生物质炭，21.46 g/kg）、C+Ca。结果表明：各处理土壤微生物量碳、氮以及可溶性有机碳具有相同的变化趋势，即前期（3 d内）都增加较快，在第3天达到最大值，随试验进行有所下降，配施效果优于单施。各处理可溶性有机氮在21 d内缓慢增加；第21天时，C+Ca、Ca、C相比CK分别显著增加了62.1%，55.5%，40.9%；35 ...

Shuitu Baochi Xuebao, 2004 通过田间氮磷肥配施试验研究了氮磷配施对黑土玉米农田生态系统玉米不同生育时期微生物量碳、氮的影响。微生物量随玉米不同生育期的动态变化表明,氮磷肥对微生物量碳和微生物量氮的动态影响并不同步,微生物量碳和微生物量氮变化最显著的时期均是授粉期,但此时微生物量碳是最低的谷值,而微生物量氮是最高的峰值。不同氮磷配比对微生物量碳影响的回归分析表明,氮肥是影响微生物量碳的主导因素,无论是适量施用还是过量施用都是氮肥对微生物量碳的影响较大。不同氮磷配比对微生物量氮影响的回归分析表明 ...

退化马尾松林恢复过程中芒萁覆盖对土壤微生物生物量碳氮及其周转的影响
Shuitu Baochi Xuebao, 2023 为探究侵蚀退化红壤马尾松林恢复过程中林下芒萁对土壤微生物生物量碳氮月动态及其周转的影响,以不同恢复年限的马尾松林为研究对象,对比分析马尾松林恢复过程中林下保留芒萁、去除芒萁处理和林下裸地土壤中12个月的土壤微生物生物量碳(MBC)和微生物量氮(MBN)含量及其周转速率、周转时间和流通量,并分析其与土壤理化性状的关系。结果表明:(1)保留芒萁覆盖处理的MBC和MBN平均含量分布比林下裸地提高26.99%~277.31%和13.54%~173.39%,而去除芒萁处理分布比保留芒萁处理降低12.29%~27 ...

Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT The polyanionic compound Na3V2(PO4)3 (NVP) has emerged as a competitive cathode material for sodium‐ion batteries (SIBs), owing to its high‐voltage redox activity (3.4 V vs. the Na+/Na reference couple) and NASICON‐type framework that enables superior ionic conductivity.

Functional Ecology, Volume 39, Issue 12, Page 3504-3516, December 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Nitrogen (N) deposition strongly affects litter decomposition and nutrient release, thereby reshaping carbon cycling in terrestrial ecosystems. Although most studies have focused on above‐ground litter, the effects of N addition on fine root decomposition and their ...

New Phytologist, Volume 247, Issue 6, Page 2616-2629, September 2025.Summary Seagrasses are important contributors to environmental nutrient cycling in marine ecosystems and can improve water quality by absorbing excess nitrogen (N). However, these ecosystems are vulnerable to human‐mediated pressures, including marine heatwaves (MHWs), particularly those of longer duration. We performed an experiment simulating a 30‐d,
