Gaoya dianqi, 2022 针对高压XLPE电缆缓冲层烧蚀故障频发，缓冲层烧蚀影响因素较多，难以准确评估在运电缆缓冲层状态的情况，提出了一种缓冲层状态模糊综合评估方法。根据缓冲层烧蚀故障机理及带材特性，建立状态评估因子及评估分级标准。在此基础上，采用改进层次分析方法确定评估因子的权重。采用模糊综合评价方法，计算缓冲层状态评估等级隶属度向量。根据最大隶属度原则确定最终评估结果。通过实例计算表明，该评估方法能够对缓冲层状态进行准确评估，有效降低人的主观因素影响，为制定在运高压XLPE电缆缓冲层状态运维管控措施提供了科学依据。

Wildlife Letters, EarlyView.Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

Evaluation System of Marine Protected Area Based on Social-ecological Systems（SESs） [PDF]
, 2016 海洋保护区是保护典型海洋生态系统和生物多样性、拯救珍稀濒危物种的重要工具。目前海洋保护区数量和面积不断增加，但许多海洋保护区并未得到有效的管理，“纸上公园”式的保护区仍大量存在，保护效果不理想。保护区管理效果差的重要原因之一是缺乏定期的跟踪或对比评估，对管理中存在的问题认识不清；因此开展保护区评估对促进管理行动的适应性调整、提升管理水平非常重要。 当前保护区管理效果评估研究存在的主要问题是：评估研究对象以陆地类型的保护区为主，缺乏适用于海洋保护区特性的评估体系；评估偏重管理过程 ...

Wildlife Letters, EarlyView.Using a 3‐year, broad‐scale camera‐trap network in western Kansas, we tested whether coyotes and American badgers exhibit spatiotemporal patterns consistent with coordinated hunting. Despite high diel activity overlap, detection‐conditioned co‐detections occurred far less frequently than expected under independence, and short‐term temporal sequencing ...
