秦岭自然保护区群的社会效益计量研究

秦岭自然保护区群在我国生物多样性保护方面发挥了重要作用,学术界一直缺乏其社会效益计量的研究.该研究在界定秦岭自然保护区群社会效益的概念及分析其内涵的基础上,综合运用专家咨询法及文献参考方法,初步建立了秦岭自然保护区群社会效益计量指标体系,包括:社会文明进步、人类健康和社会生产生活改善3种类型11项指标.利用市场价值法、等效替代法等方法,对秦岭自然保护区群保护生物多样性的过程中所产生的社会效益进行了计量及分析.结果表明:秦岭自然保护区群在保护生物多样性的同时,每年产生了相当可观的社会效益,总货币量约11.68亿元人民币,与周边区域密切相关的社会文明进步效益为1.68亿元;人类健康效益为1.62亿元;社会生产生活改善效益为8.37亿元.该研究的社会效益计量指标及计量方法可为秦岭自然保护区群基层工作人员及类似保护区社会效益计量及评价提供参考.     

四川龙泉湖自然保护区可持续性评价与撤销建议

龙泉湖自然保护区位于川中盆地西缘,以石盘水库为保护对象。本文首先从自然生态条件、资金与管理、周边社区发展3方面,选取稀有性、多样性、自然性、典型性、面积适宜性、资金状况、管理状况、社区发展8项指标,构建我国自然保护区可持续性综合评价的指标体系。对于面积适宜性,笔者统计得出判别功能区面积比是否适宜的标准,将该指标具体细化。核心一缓冲一实验区面积的合理比例约为0．4：0．1～0．2：O．5～0．4。以这一指标体系,对该保护区予以评分,验证该指标体系的可操作性。评分结果龙泉湖保护区仅得33分,处于不可持续水平。限制因素在自然生态、管理方面,尤其是生态功能重要性太低。进而分析该保护区不具备自然属性,动、植物物种数占四川省的比例很小,无特殊保护价值;且至今未设立保护区管理机构,无专业管护人员,不能履行管理职责。因此,本文建议撤销龙泉湖省级自然保护区,改设为省级水利风景区或湿地公园。     

白马雪山国家级自然保护区与周边社区冲突分析

针对白马雪山国家级自然保护区与周边社区村民在环保观念、管理模式、资源利用以及补偿措施等方面的矛盾冲突,对其产生的原因进行了分析,并从社区经济发展、社区村民传统生活习惯约束、社区管理机构完善和少数民族传统文化有效利用等方面提出了主要的缓解冲突的措施和方法。     

安全生产职业培训中“安全本质”的教学思考

从提高安全生产职业培训有效性的角度,提出"安全本质"的哲学机理与数理机理,以及安全本质的认知对安全生产职业培训的积极意义。针对当前安全生产培训教育中,多限于事故案例警示教育、法律条文解释和一般安全生产管理知识的宣教的现状,提出深层认知安全本质的方法及其认知价值。通过安全本质的认知定义域划分,安全本质哲学机理和数理机理的定义,安全本质定义的认知价值,分析与探讨了安全科学体系中"安全本质"定义的构造。目的是在辩证认识中,既认知"事故发生可能性"存在的绝对性,又认知一定时空条件下,事故是可以预防的相对性,从而强化培训对象的安全生产管理意识,提升安全生产职业培训的实效性。     

Nature Documentaries,Connectedness to Nature,and Pro-environmental Behavior

We investigate the effects of nature documentaries on pro-environmental cognition and behavior. Of central interest is the concept of connectedness to nature, which describes an individual's sense of being connected to nature. Based on previous research showing that a direct nature experience in zoos can increase connectedness to nature, we questioned whether watching a nature documentary could increase connectedness to nature and pro-environmental behavior. An experiment using one control group (watching a documentary about Einstein's theory of relativity) and one treatment group (watching a nature documentary) revealed that a mediated nature experience is not sufficient to elicit an increase in connectedness to nature. However, we found that exposure increased actual donation behavior for animal and environmental protection organizations. It is important to note that nature documentary exposure increased pro-environmental donation behavior only in those already having a strong sense of connectedness. We discuss real-world implications for donation-accepting, non-profit organizations.     

Following Old Paths or Shaping New Ones in Natura 2000 Implementation? Mapping Path Dependency in Instrument Choice

This article reviews the influence of two specific European Union (EU) laws, the Birds and Habitats Directives, on the choice of national policy instruments by Member States. Both Directives leave the choice for policy instruments to manage the sites designated under the Directives to the Member States. Using path dependency as a leading concept, this article analyses the continuity or changes in policy instruments due to the implementation of the Directives in 15 countries. This article shows that the tendency to use existing instruments to implement EU policy is limited, as in almost all countries new instruments were developed. Yet, states do tend to choose instruments from their predominant policy instrument mix and preferred implementation style to address the management requirements of the Directives. Additionally, in Central and Eastern European countries where the implementation of EU policy coincided with a process of transition to a market economy, new instruments were introduced outside the existing implementation style. The introduction of new policy instruments is the result of historical turns, domestic pressure and a shift to new modes of governance. National case studies are needed to shed more light on the interaction between EU policy and domestic factors during the process of instrument choice.     

Inventories and maps: cognitive ways of framing the nature policies in Europe

Since the Earth Summit in Rio, declining biodiversity has become a subject of general concern for many countries. To counter these negative trends, government nature policies in Europe at least are now thought out primarily in terms of networks. They concern new areas outside nature reserves, new players and new management strategies. Consequently, these policies should themselves become the subject of new public debate. Our study concerns the analysis of the forms used to collect the data required to set up the European Union's Natura 2000 network and maps drawn as part of the Council of Europe's Pan-European Ecological Network strategy. The aim of this article, which takes the perspective developed by the sociology of science, will be to show how the forms and maps used in these new nature policies produce knowledge that precedes policy discussions to search for the best possible socio-political compromises. In other words, the knowledge that is collected in and by means of these documents, forms and maps offers a cognitive way of ‘framing’ the subsequent public debates.

武夷山自然保护区资源管理中社区参与机制的探讨

武夷山自然保护区在处理自然保护与社区发展之间的关系以及推动社区参与保护区管理方面已取得了一些成功的经验。但是,从当地现有的社区参与管理的模式来看,不仅社区参与程度较低,而且在某种程度上处于被动参与状态,保护区缺少一种激励机制来引导群众自觉参与保护。作者提出了在保护区建立旅游股份合作制公司的构想,并阐述了其运行机制。
