Impacts of natural variability and external forcing on regional sea level change [PDF]
, 2015 全球平均海平面正在上升，预测在未来还会继续上升。海平面变化在空间上并不是均匀一致的，人们更关心的是区域性海平面变化。然而，区域性海平面往往表现出相当大的气候系统内部产生的自然变动，这使得外部强迫（包括温室气体、气溶胶等人为因素，火山爆发、太阳循环等自然因素）引起的区域性海平面变化不甚明显，同时也为未来区域性海平面变化预测带来很大的不确定性。 基于参加耦合模式比较计划第五阶段（CMIP5）的气候模式，设计了两种方法来衡量区域性尺度上外部强迫引起的海平面变化信号与海平面自然变动信号的相对强度 ...

Conservation Biology, EarlyView.Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...

Defining and identifying relevant stakeholders to advance effective conservation
Conservation Biology, EarlyView.The challenge of defining stakeholders in environmental science and an approach for refining existing definitions. Abstract Stakeholder is a contested term that has spawned a multitude of ad hoc definitions. The ambiguity of these definitions has oftentimes impeded transdisciplinary research in environmental governance and conservation science because ...

Jianzhu Gangjiegou Jinzhan, 2011 大跨度空间钢结构作为重要的公共设施,其安全性问题直接关系着国计民生,随着大跨度空间钢结构理论与实践经验的逐渐成熟和完善,其跨度也在逐渐增大。地震载荷作用下,在空间结构设计中考虑地震动的多维多点输入变得十分必要。本文对大跨度空间钢结构多维多点输入抗震的研究现状进行了系统的综述和总结,阐述并评价了现行大跨度空间钢结构考虑多维多点输入的3种抗震计算方法,即时程分析法、随机振动分析法和反应谱法。最后,对今后空间钢结构仍需要进一步研究的问题提出了建议和展望。
