陕西宁陕自然保护区的现状及保护对策

open access: yes野生动物学报, 2006
宁陕自然保护区是秦岭大熊猫保护区群的东缘地带,也是秦岭大熊猫保护区群向东延伸的纽带,更是秦岭大熊猫保护区群最有保护价值的保护区之一。本文阐述了宁陕自然保护区生物资源状况、建立的重要性及大熊猫的种群状况、社区经济概况、机构设置及管理情况,并提出了保护区存在的问题及具体的保护管理对策。

东北豹保护对策研究

open access: yes野生动物学报, 2012
通过概述世界上东北豹的种群数量特征和分布状况,分析了东北豹保护面临的各种威胁和问题,如人类过度干扰、乱砍滥伐、乱捕滥猎、近亲繁殖以及人类的开发建设等活动对栖息地造成的严重破坏,使栖息地呈片段化、破碎化发展趋势,直接威胁东北豹种群的生存和繁衍。中国对东北豹的保护没有足够的重视,还没有建立专门的东北豹自然保护区,而俄罗斯对于东北豹的保护非常重视,不但建立了专门的东北豹自然保护区,还完善了东北豹的各项保护措施。最后,针对上述情况,提出了东北豹栖息地保护、猎物种群恢复、东北豹的重引入 ...

Biodiversity‐driven spatial conservation planning to delineate temporally stable regions

open access: yesConservation Biology, EarlyView.
Abstract The accelerating loss of biodiversity underscores the critical need for effective conservation strategies, particularly in the face of climate change and anthropogenic pressures. We devised a conservation planning framework that adopts a temporal stacking approach to species distribution models and landscape connectivity analyses. These models

对TDHM技术提高光网络被保护容量的探究

open access: yesGuangtongxin yanjiu, 2017
新型时域混合调制(TDHM)技术可以提高光通道的频谱使用效率,有效地提高光网络的容量。针对共享备份路径保护(SBPP)技术下的波分复用(WDM)光网络,我们结合TDHM技术研究了路由和波长分配(RWA)问题,并提出了一种基于最佳路径对策略的优化技术。仿真结果表明,与传统的最短路径策略优化技术相比,提出的最佳路径对策略能使被保护的网络容量提高30%,从而验证了TDHM技术对提高光网络传输容量的有效性。

Defining and identifying relevant stakeholders to advance effective conservation

open access: yesConservation 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 ...

计及继电保护失效的断路器检修顺序决策方法

open access: yesGaoya dianqi, 2017
多台断路器存在最优检修时间段重叠情况,为了合理配置检修资源,应该对断路器实施差异化检修,决策多台断路器检修顺序及检修重点。针对上述问题,从断路器潜在风险分析出发,考虑断路器关联继电保护的影响,提出了计及继电保护失效的断路器检修决策及检修效果评价方法。通过建立计及关联继电保护失效的断路器状态空间模型,综合考虑断路器退出运行时系统风险增量及继续运行的潜在风险,建立断路器检修紧迫度指标决策断路器检修顺序。以IEEE-RBTS进行算例分析 ...
