Nitrogen Transports and Transformations in Mangrove Sediments using Nitrogen Isotope Techniques in China [PDF]
, 2012 人类活动对生态系统的影响日益扩大，过量施肥、化石燃料的燃烧等引发的氮(N)负荷迅速增加。陆地生态系统过剩的N通过流域汇集至河口和海岸，威胁着海洋生态系统的健康。目前，全球N循环正致力于揭示河口和海岸地区N的源汇格局及主导机制。红树林湿地广泛分布于热带、亚热带河口和海岸地区，作为陆源营养盐入海过渡带，在缓解陆源N输入方面扮演着重要角色，成为了研究的热点。 本研究利用N稳定同位素技术，将现场培养与室内模拟培养相结合，揭示了我国东南沿海典型河口和海湾红树林湿地沉积物总氮沉积、固氮作用、反硝化作用 ...

Shuitu Baochi Xuebao, 2022 通过定点监测刺槐林土壤水分含量,探究不同林龄刺槐林土壤水分分布与亏缺程度。采用空间代替时间的研究方法,选择10,15,25,40年人工刺槐林为研究对象,农地(0年)为对照,调查分析0—200 cm土层土壤水分分布情况。结果表明:各样地平均土壤含水量大小顺序为农地(18.80%)＞10年刺槐林(16.43%)＞15年刺槐林(15.47%)＞40年刺槐林(13.87%)＞25年刺槐林(13.38%);不同林龄刺槐林土壤水分均处于亏缺状态,随着林龄增加,土壤水分亏缺呈增大趋势,平均土壤水分亏缺程度为19.38%

Ultrasound in Obstetrics &Gynecology, Volume 64, Issue 6, Page 768-775, December 2024.Abstract Objective Lower urinary tract obstruction (LUTO) is a chronic condition with a spectrum of outcomes. It is usually suspected prenatally based on ultrasound features (USFs). Given the unknown postnatal trajectory and the potential for significant morbidity and mortality, many families choose termination of pregnancy (TOP), often based on USFs ...

Integrative Conservation, Volume 3, Issue 1, Page 58-75, March 2024.Local populations are aware of the decline and disappearance of Detarium species in their habitats, attributing this trend to excessive human exploitation and the effects of climate change. Thus, Detarium plant resources may face challenges in forests with different levels of protection status due to habitat fragmentation and the effects of climate ...
