People and Nature, Volume 7, Issue 11, Page 2700-2713, November 2025.Abstract Large old trees are important ecological entities in human settlements, providing cultural values and ecological services that are threatened by current and future changes in global climate, land use and disturbance regimes. Some studies suggest incorporating social and cultural significance into the conservation of large old trees.

Integrative Conservation, Volume 4, Issue 3, Page 476-490, September 2025.The leaf functional traits of angiosperms and gymnosperms in mountain ecosystems significantly influence phyllosphere fungal diversity. These traits are critical for understanding fungal stress resistance and elevational adaptation, which aids in predicting plant responses to climate change.

Religious uses shape the selection and distribution of Chinese Buddhist tree species
People and Nature, Volume 7, Issue 9, Page 2094-2105, September 2025.Abstract As a widely disseminated world religion, Buddhism's selection of religious species may profoundly impact candidate species distribution. This study sampled 246 Chinese temples covering diverse regions to investigate the selection modes of Buddhist tree species (BTS) and the alien religion's influence on Chinese indigenous biodiversity and ...

Jianzhu Gangjiegou Jinzhan, 2011 为了研究实腹式钢骨混凝土异形柱在偏心荷载下的破坏机理、受力性能及变形能力。本文通过对12个十字形钢骨混凝土异形柱进行偏心受压承载力的试验研究,观察了含钢率和偏心距不同情况下的试件受力过程和破坏形态,分析了钢骨混凝土异形柱的荷载-位移曲线、承载力、位移延性等力学性能。通过试验,明确了钢骨混凝土异形柱的破坏特征,含钢率对承载力的影响。试验结果表明,含钢率越大,构件的承载力及延性也会相应增加,钢骨混凝土异形柱具有较高的承载能力和较好的延性。

Jianzhu Gangjiegou Jinzhan, 2007 本文分析了半刚性连接组合梁框架的在水平荷载作用下的受力特性,提出了对于具有合理构造措施的半刚性连接框架,采用塑性分析方法进行在水平荷载作用下的框架整体极限承载能力、组合梁的承载能力及框架柱的承载能力验算。采用塑性分析方法可使设计计算工作量极大地降低,而且能给出较为安全和准确的分析结果,这可供半刚性连接框架的实际设计参考。

Jianzhu Gangjiegou Jinzhan, 2021 对7根设肋薄壁方钢管混凝土柱进行了拟静力试验,研究了加劲肋设置数量、轴压比和长细比对试件的承载能力、延性和耗能能力的影响。同时使用ABAQUS软件对带肋薄壁方钢管混凝土柱进行了受力全过程分析,模拟结果与试验结论基本一致。研究结果表明:在达到承载力前,无肋试件已经发生鼓曲,鼓曲在达到承载力后迅速增大从而导致焊缝开裂,钢管对混凝土的作用未充分发挥时试件就已破坏。带肋试件由于加劲肋对外部钢管的拉结作用,延缓了试件局部鼓曲的发生,试件材料性能得以充分利用,因此带肋试件的承载力、延性性能和耗能性能均优于无肋试件 ...
