Carbon Sequestration and Balance in Kandelia candel Plantation Ecosystem in Jiulongjiang Estuary [PDF]
, 2012 本文选择福建九龙江口不同发育阶段（中龄林、成熟林）的秋茄红树林为研究对象，通过测定秋茄红树林林木层各器官、凋落物层和土壤层含碳率，结合各组分生物量和年净生产量，计算了秋茄红树林生态系统的碳储量和不同发育阶段秋茄林的年净固碳量。于2010年5月至2011年4月，采用LI–8100全自动土壤CO2通量测定系统，研究了不同林龄秋茄林的土壤呼吸的日动态、月动态与季节差异，及其土壤水热因子对土壤呼吸的影响。通过测定样地的土壤含碳率和碳储量，以及秋茄林生态系统地上部分的年固碳量，分析评价了秋茄红树林生态系统的碳源 ...

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,
