Identifying and developing effective post‐2020 conservation bridging leaders
Conservation Biology, Volume 36, Issue 6, December 2022., 2022 Abstract Effective bridging leaders interact within and outside their group to facilitate collaboration required in multistakeholder contexts. This is particularly crucial to community‐based conservation interventions that strive to achieve both ecological and social objectives by actively engaging or devolving decision‐making and management authority ...

Disasters, Volume 46, Issue 1, Page 141-161, January 2022., 2022 The aim of this study is to investigate what women do in disaster situations and how both men and women perceive and discuss the work of women. These patterns were evidenced in the stories that were told following the largest forest fire in the modern history of Sweden in July 2014.

Setting goals for pollinator gardens
Conservation Biology, Volume 39, Issue 4, August 2025.Abstract In recent years, declines in animal pollinators have stimulated tremendous interest in pollinator‐friendly gardening. There is a widespread notion that pollinator gardens are beneficial, but the specific capacity of pollinator gardens to improve biodiversity conservation and societal well‐being remains unclear.

Engaging youth in biodiversity education through visual narrative
Conservation Biology, Volume 38, Issue 6, December 2024.Abstract Engaging youth in early and sustained conservation education has important implications for promoting positive attitudes and behaviors in those who will become the future of conservation and management. Toward this goal, visual narratives (comic books, graphic novels) are an increasingly popular method used by conservation scientists to ...

Dianci bileiqi, 2012 对国内±800 kV直流输电工程共用接地极,根据已建成向家坝-南汇±800 kV直流输电工程的相关参数,利用电磁暂态计算软件PSCAD分别搭建了两个特高压直流输电系统换流站共用接地极的仿真计算模型,对送受两端采用独立接地极和共用接地极进行对比。并结合云广和贵广Ⅱ共用接地极的实际情况,分析其共用接地极影响。结果表明:当其中一个直流系统转为单极大地回线运行方式或双极电流不平衡运行方式时,会产生中性点电压偏移。电压偏移会影响直流系统的稳态运行电压水平。为减小电压偏移问题,在设计共用接地极时 ...

Dianci bileiqi, 2021 为了研究直流接地极周围金属管道的缓解线防护措施对降低管道泄漏电流密度防护效果的影响,通过CDEGS软件,建立了直流接地极、埋地金属管道和缓解线防护装置的仿真计算模型,依次分析缓解线敷设位置、缓解线与管道距离、缓解线与管道连接方式、缓解线半径、接地极和土壤参数对防护效果的影响,并得出如下结论:缓解线在管道的靠近直流接地极侧敷设比远离直流接地极侧敷设的效果更优;缓解线与管道间距离对防护效果的影响不明显,但缓解线靠近管道时的防护效果稍好;通过减小电缆连接线的间隔距离或增大缓解线半径的方式 ...

Gaoya dianqi, 2010 针对直流落点增多与接地极选址越来越困难的矛盾问题,设计一种新型接地极设计方案——广域接地极。据此,首先建立了广域接地极的等效数学模型,该模型辅以场路耦合算法可以对分流情况和运行工况进行计算。随后根据广东电网直流工程现状和后续直流建设情况构建了广东电网广域接地极,并进行了可行性分析。结果表明,广域接地极辅以合适的均流措施可以满足多回直流共用的需要,且具备长期解决后续直流工程接地极问题的理论可行性,值得进一步研究。

Dianci bileiqi, 2020 准确计算直流接地装置的散流性能及接地特性是优化设计直流接地极的基础。提出了基于恒定电场理论的直流接地装置性能有限元数值计算模型,针对求解区域和接地导体截面尺寸的差异导致的剖分困难、计算量大的问题,引入"薄壳"理论,在保证计算精度的前提下大大减小了计算量;通过与文献数据对比,验证了该方法的有效性。建立典型结构的深井型接地极模型,计算深井接地极散流过程产生的地中电流密度、电场强度、接地电阻和最大跨步电压等参数;分析电流注入点个数、接地极导体长度、接地极埋深、导体并联根数以及土壤电阻率等因素对接地性能的影响 ...
