羌塘高原美马错自然保护区的初步评价 总被引:4,自引:1,他引:4
拟建的羌塘高原美马错自然保护区是我国青藏高原高寒草原生态系统保存最完好的地区之一,区内含有野牦牛、藏野驴、藏羚等多种珍稀野生动物,其密度之高为西藏所仅见。该地区具有极高的自然保护价值,应作为代表青藏高原高寒草原生态系统的典型地区,列为国家级自然保护区。 相似文献

Urban ecology is emerging as an integrative science that explores the interactions of people and biodiversity in cities. Interdisciplinary research requires the creation of new tools that allow the investigation of relations between people and biodiversity. It has been established that access to green spaces or nature benefits city dwellers, but the role of species diversity in providing psychological benefits remains poorly studied. We developed a user‐friendly 3‐dimensional computer program (Virtual Garden [ www.tinyurl.com/3DVirtualGarden ]) that allows people to design their own public or private green spaces with 95 biotic and abiotic features. Virtual Garden allows researchers to explore what elements of biodiversity people would like to have in their nearby green spaces while accounting for other functions that people value in urban green spaces. In 2011, 732 participants used our Virtual Garden program to design their ideal small public garden. On average gardens contained 5 different animals, 8 flowers, and 5 woody plant species. Although the mathematical distribution of flower and woody plant richness (i.e., number of species per garden) appeared to be similar to what would be expected by random selection of features, 30% of participants did not place any animal species in their gardens. Among those who placed animals in their gardens, 94% selected colorful species (e.g., ladybug [Coccinella septempunctata], Great Tit [Parus major], and goldfish), 53% selected herptiles or large mammals, and 67% selected non‐native species. Older participants with a higher level of education and participants with a greater concern for nature designed gardens with relatively higher species richness and more native species. If cities are to be planned for the mutual benefit of people and biodiversity and to provide people meaningful experiences with urban nature, it is important to investigate people's relations with biodiversity further. Virtual Garden offers a standardized tool with which to explore these relations in different environments, cultures, and countries. It can also be used by stakeholders (e.g., city planners) to consider people's opinions of local design.

Conservation conflicts are gaining importance in contemporary conservation scholarship such that conservation may have entered a conflict hype. We attempted to uncover and deconstruct the normative assumptions behind such studies by raising several questions: what are conservation conflicts, what justifies the attention they receive, do conservation-conflict studies limit wildlife conservation, is scientific knowledge stacked against wildlife in conservation conflicts, do conservation-conflict studies adopt a specific view of democracy, can laws be used to force conservation outcomes, why is flexibility needed in managing conservation conflicts, can conservation conflicts be managed by promoting tolerance, and who needs to compromise in conservation conflicts? We suggest that many of the intellectual premises in the field may defang conservation and prevent it from truly addressing the current conservation crisis as it accelerates. By framing conservation conflicts as conflicts between people about wildlife or nature, the field insidiously transfers guilt, whereby human activities are no longer blamed for causing species decline and extinctions but conservation is instead blamed for causing social conflicts. When the focus is on mitigating social conflicts without limiting in any powerful way human activities damaging to nature, conservation-conflict studies risk keeping conservation within the limits of human activities, instead of keeping human activities within the limits of nature. For conservation to successfully stop the biodiversity crisis, we suggest the alternative goal of recognizing nature's right to existence to maintenance of ecological functions and evolutionary processes. Nature being a rights bearer or legal person would imply its needs must be explicitly taken into account in conflict adjudication. If, even in conservation, nature's interests come second to human interests, it may be no surprise that conservation cannot succeed. 相似文献

在人与环境所组成的世界系统中,人与环境、人与人是两种最基本的关系,它们之间相互依存并相互影响。在人类社会的生存阶段与发展阶段中,两种关系表现出明显不同的作用性质与作用内容。当今世界,人类社会所面临的发展危机(贫富分化与资源环境问题)均直接表现为两种关系的矛盾冲突。分析表明.只有同时实现人与环境的和谐以及人与人之间的公平,才有可能实现可持续发展。 相似文献

循环经济的范式研究 总被引:1,自引:0,他引:1
冯之浚 《中国人口.资源与环境》2007,17(4):10-13
发展循环经济是落实科学发展观、实现经济增长方式根本性转变的重要途径。借鉴“范式”理论探讨和研究了循环经济范式替代末端治理范式的变革:①自然资源的价值得到重估。循环经济范式中将自然资源列为最重要的资源形式。认为它是人类社会最大的资源储备,提高资源生产率是解决环境问题的关键。②不同生态伦理得到整合、提升。循环经济的生态伦理基础强调“生态价值”的全面回归.主张在生产领域和消费领域向生态化转向,承认“生态位”的存在和尊重自然权利。它既包含了现代人类中心主义、生命中心主义和生态中心主义兰种生态伦理追求人类道德完善的合理成分。又补充了各自其不完善的方面o③生态阈值的研究得到深化。循环经济范式的基本前提之一是认为生态阈值是客观存在的。强调在生态阈值的范围内合理利用自然资源.从原来的仅对人力生产率的重视转向在根本上提高资源生产率。在尊重自然的基础上切实有力地保护生态系统的自组织能力。实现经济发展和环境保护的目的。④深层生态学的研究得到加强。循环经济范式是一种深层生态学。符合天人调谐的理念。它不仅强调技术进步.而且将制度、体制、管理、文化等因素通盘考虑,注重观念创新和生产、消费方式的变革.树立了人与自然和谐发展的价值观念。 相似文献

Trends in plant cover synanthropization along a plain-foothills-mountains gradient have been revealed in the reserve. Characteristics of plant communities in anthropogenically disturbed habitats, centers of concentration of anthropophytes and apophytes, and pathways of their migration are described. 相似文献

环境伦理的突出功能表现在对人与自然关系的调整上。从法学视角切入.以“权利”作为分析文本.论述了人类中心主义与非人类中心主义在“自然权利”上的理论分歧.人类中心主义者从权利的一人性、权利义务的不对等性、主张自然权利的非现实性以及自然权利的不可操作性四个方面对自然的权利提出了批判.而非人类中心主义者指出权利撅念的在不断地扩展.人类中心主义不可能完全解决好人与自然的关系,自然权利存在着转化为在法律上具有可操作性的可能.并且自然权利理论已在法律实践领域拓展.对自然的权利进行了辩护。由此提出了“非人类中心主义”、“自然的权利”的环境伦理定位。 相似文献

An inventory of rock vegetation has been taken in river valleys on the eastern slope of the southern part of the Northern Urals and the northern part of the Middle Urals. New habitats of some rare plant species, relict communities of forest-steppe species at the northern limit of their distribution, and ultrasmall populations of petrophilous species growing in isolation for a long time have been revealed. In studies on a group of similar specially protected areas (e.g., within river valleys), it is proposed to identify key sites distinguished by the highest species richness of vegetation 相似文献
