Identifying priority areas for conservation to promote connectivity and mitigate the impacts of anthropogenic disturbance

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract As nations seek to expand protected area (PA) networks to cover 30% of land and seas by 2030 (30×30), there is an urgent need for systematic conservation planning and spatial prioritization that considers the broad range of ecological and socioeconomic factors influencing the persistence of biodiversity.

Effects of human demand on conservation planning for biodiversity and ecosystem services

open access: yesConservation Biology, Volume 33, Issue 4, Page 942-952, August 2019., 2019
Abstract Safeguarding ecosystem services and biodiversity is critical to achieving sustainable development. To date, ecosystem services quantification has focused on the biophysical supply of services with less emphasis on human beneficiaries (i.e., demand).

不同电极结构下SF6气体临界击穿场强计算

open access: yesGaoya dianqi, 2022
SF6气体在电力绝缘设备中的应用已经非常广泛,计算多种电极结构下SF6气体临界击穿场强对于研究SF6气体放电击穿特性具有重要意义。文中针对SF6气体在多种电极结构下的放电击穿过程开展了详细的理论研究与计算分析。首先,基于已有的SF6气体击穿过程进行理论总结并加以完善;然后,引入阶段先导发展模型,针对稍不均匀电场条件下SF6气体放电击穿过程进行建模,将放电击穿分为3个主要过程:首电子产生阶段、流注初始阶段及先导发展至击穿阶段;最后,结合气体物性参数建立多种电极结构下SF6气体折合临界击穿场强计算综合模型 ...

Primary saltmarsh succession on a tropical coral island in the South China Sea: Human influences initiate and accelerate the process of succession

open access: yesEcological Solutions and Evidence, Volume 6, Issue 2, April–June 2025.
Pioneer grass species rapidly colonized the site within 1 year following land reclamation, with a grass‐to‐shrub transition concurrently with dike construction, indicating a clear trajectory of species establishment and development in a newly formed saltmarsh.

Incorporation of human–wildlife interactions in ecosystem‐based management to enhance conservation of endangered guitarfish

open access: yesConservation Biology, Volume 38, Issue 6, December 2024.
Abstract Growing human use of the marine environment increases the proximity of humans to marine wildlife and thus likely increases human–wildlife interactions. Such interactions influence perceptions of nature and promote or undermine conservation. Despite their importance, human–wildlife interactions are rarely considered in ecosystem‐based marine ...

10kV架空配电线路感应雷过电压暂态特性分析

open access: yesDianci bileiqi, 2014
研究架空配电线路的感应雷过电压特性对分析配网雷击风险有重要意义。基于传输线模型和电磁场理论,计算了回击过程产生的空间电磁场,先导发展过程产生的静电感应影响了线路上的过电压波形。采用Agrawal场线耦合模型和时域有限差分法(FDTD)求得导线上产生的散射电压。通过与文献实测结果对比,验证了方法的有效性。针对典型的10kV架空配电线路,分析了先导发展速度、雷击点与导线间的水平距离、导线高度和雷电流幅值不同时的感应过电压波形特性。结果表明:先导发展速度越快,感应雷过电压波前时间越短,过电压幅值越大 ...
