鄱阳湖南矶湿地“点鸟奖湖”生态激励机制的实践与探讨

open access: yes野生动物学报, 2017
江西鄱阳湖南矶湿地国家级自然保护区位于鄱阳湖主湖区南部,赣江入鄱阳湖的三角洲水域。其特殊的地理位置孕育了非常丰富的鱼类资源和生物多样性,是许多迁徙水鸟的重要越冬地。保护区成立后湿地资源虽得到有效保护,但如何正确处理渔业生产和资源保护的问题,一直困扰保护区管理者。为缓解社区矛盾,保护区开展了“点鸟奖湖”等一系列活动,补偿社区渔民损失。通过这些活动,提高社区民众参与保护鸟类的热情,建立保护区管理者和社区民众的互信,达到保护与发展双赢的效果。关系到社区居民的发展是所有保护区管理人员必需考虑到的问题,“点鸟奖湖”

自然保护区发展与资源的合理利用

open access: yes野生动物学报, 1999
生物多样性的保护与自然资源的持续利用,已经成为当今世界“环境与发展”的热点研究问题,越来越受到人们的关注.自然保护区是生物多样性保护的主要形式之一,它不仅为保护和持续利用自然资源提供了可能;而且也成为研究生物多样性的重要基地.运用科学区划及有效管理手段,充分利用保护区中实验区和缓冲区中的资源,是保护区获得较高的经济、社会和生态效益的有效途径.保护区如何以积极、务实的态度,发展经济,增强活力,缩小保护与利用的矛盾,把保护管理与持续利用有机地结合起来,对促进保护区的建设和发展显得尤为重要.笔者认为 ...

Functional homogenization of terrestrial mammals outside protected areas in the Hengduan Mountains, China

open access: yesConservation 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 ...

WDM网络组播连接保护切换时间分析

open access: yesGuangtongxin yanjiu, 2006
保护切换时间是衡量一个网络保护方案性能优劣的重要指标之一。文章给出了一种波分复用(WDM)网络中组播连接的保护切换模型,并在此基础上对目前主要的组播连接保护方案的保护切换时间做了理论上的分析和比较,这些方案包括link-d isjoint保护、arc-d isjoint保护和段保护。同时,结合各方案的连接阻塞率,对各方案的总体性能做了简要的分析。

Using incentive payments to promote human–carnivore coexistence

open access: yesConservation Biology, EarlyView.
Abstract For many large carnivores, minimizing the financial burden they impose on local people is critical to their conservation. Incentive‐based programs that provide people with financial benefits for taking pro‐conservation actions or achieving conservation goals are a promising tool for promoting human–carnivore coexistence. Although the number of

黑龙江大沾河湿地国家级自然保护区鸟类多样性及其保护

open access: yes野生动物学报, 2011
为了掌握黑龙江大沾河湿地国家级自然保护区的鸟类多样性和认识保护区目前存在的问题,我们通过查阅资料、鸟类环志和鸟类救护的方法对保护区的鸟类多样性进行了研究。结果表明黑龙江大沾河湿地国家级自然保护区分布有鸟类202种,国家Ⅰ级重点保护鸟类有东方白鹳、白头鹤、丹顶鹤、金雕4种,国家Ⅱ级重点保护鸟类有白枕鹤、苍鹰、鸳鸯等33种,鸟类多样性极其丰富。在鸟类保护工作方面,目前虽然保护区已经开展了大量的保护工作,但仍然存在经济发展与鸟类保护相矛盾、人为干扰严重、自然资源利用过度和环境污染加剧等问题。针对存在的问题 ...

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico

open access: yesConservation Biology, EarlyView.
Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

广东大峡谷自然保护区社区公众野生动物保护意识调查

open access: yes野生动物学报, 2010
2008年6月,对广东大峡谷自然保护区社区公众野生动物保护意识进行了问卷调查。结果表明:(1)公众对野生动物保护知识匮乏,缺乏野生动物保护法制意识;(2)公众普遍对野生动物面临的威胁有较明确的认识,具有保护意愿,但缺乏保护野生动物的积极性和主动性;(3)公众接受野生动物保护教育的主要途径是电视。本文针对广东大峡谷自然保护区公众野生动物保护意识现状及其存在的问题,提出了一些建议。

Effects of landscape context on avian specialist response to increased surface temperature in protected areas

open access: yesConservation Biology, EarlyView.
Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.
