Jianzhu Gangjiegou Jinzhan, 2022 基于高海拔地区山地和平原两类地貌1.5年的实测脉动风风速数据，确定了两类地貌风剖面指数、湍流强度的均值和98%保证概率值，分析了高海拔风场特性参数对输电线路风压高度变化系数、杆塔风振系数和导地线风振系数的影响规律，高海拔地区风剖面指数不应高于A类场地风剖面指数0.12。确定了高海拔与标准B类地貌下杆塔和导地线风荷载的差异，通过结构受力分析得到了高海拔地区杆塔应力及分布特征，两类地貌风场下杆塔最大应力比较B类地貌均有所增加，且山地地貌风场更为不利，杆件最大应力比达到了1.14 ...

Shuitu Baochi Xuebao, 2011 对冀北山地阳坡不同海拔蒙古栎天然林分枯落物层及土壤层进行了初步研究,结果表明:(1)样地二(海拔1 180 m)的枯落物总蓄积量最大为33.18 t/hm2,其次为样地三(海拔1 260 m),最小为样地一(海拔1 100 m),为14.20 t/hm2,即随海拔升高枯落物总蓄积量先增大后减小。最大持水率的变动范围为140.83%～229.81%,随海拔升高而降低。样地二的有效拦蓄力最强,为39.22 t/hm2,样地三拦蓄能力最弱,为20.58 t/hm2,即中海拔拦蓄能力最强,高海拔最弱。(2 ...

Functional Ecology, Volume 39, Issue 9, Page 2327-2341, September 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract While elevational patterns of soil bacterial and fungal communities in mountain ecosystems have been well documented, the assembly processes of soil archaeal and protistan communities, and their linkage with ecosystem multifunctionality (EMF), remain poorly understood ...

野生动物学报, 1999 小熊猫在高黎贡山不断受到人为干扰,生存环境日益缩小.调查表明,东坡小熊猫主要在海拔28003100m活动,西坡小熊猫主要在海拔28003500m活动,冬季生境密集利用带为海拔28003000m,春季以后为海拔33003500m,并主要在山脊活动.这些现象均与躲避人类有关.

New Phytologist, Volume 247, Issue 3, Page 1460-1473, August 2025.Summary Podocarpus pollen morphology is shaped by both phylogenetic history and the environment. We analyzed the relationship between pollen traits quantified using deep learning and environmental factors within a comparative phylogenetic framework.

Dianci bileiqi, 2015 海拔条件对绝缘子的沿面闪络电压会产生影响,使得不同海拔地区电力设备的外绝缘配置产生差异,需要加强绝缘子闪络电压随海拔高度变化规律的试验研究。对不同海拔高度地区（武汉、昆明两地）10 kV线路常用绝缘子的冲击和工频沿面闪络电压进行了试验研究,对多次试验结果按Weibull概率分布的方法进行了处理,得到不同闪络概率的闪络电压,进而完善了绝缘子闪络电压随海拔高度变化规律的经验公式,为不同海拔条件地区的外绝缘设计提供参考。

Applying Bergmann's Rule to Species Conservation Planning 贝格曼法则在物种保护规划中的应用
Integrative Conservation, Volume 4, Issue 2, Page 120-125, June 2025.Although Bergman's rule has extensively been studied, its implications in species conservation have not been clear, especially in the context of climate change (global warming). Here, we discuss the potential applications of the “rule” based on IUCN's (2022) Red List and suggest species' body size to be an important ecological indicator in future long ...

Integrative Conservation, Volume 4, Issue 2, Page 188-204, June 2025.We assessed the distribution of 14 threatened agamid lizard species using Species Distribution Modeling to identify hotspots for these species' conservation. Based on the results, high‐priority areas of threatened agamids were projected to occur specially in the wet zone.
