中国生物多样性重点保护区评价标准探讨

从基于景观大尺度的评价和基于保护区域小尺度的评价2个层次,综述了国内外研究者在生物多样性重点区域评价方面开展的工作.尝试构建一般标准和鉴定标准的双重中国生物多样性重点保护区评价标准.其中,一般标准是作为重点保护区的基本条件,必须全部满足,而鉴定标准是依据相应指标进行判断,凡具有任意1项或多项指标的区域可被确认为重点保护区.并就指标体系和评价标准的具体内涵作了阐述.     

Reflections on the ‘sustainable development’ debate

The paper examines the way in which the term ‘sustainable development’ has been used. Beginning with a short review of responses to a publication of the author's on sustainable development, it goes on to explore the different assumptions behind the discussion of the concept, and the different dimensions of sustainability: economic, political and epistemological. It is argued that, like the environment itself, the concept of sustainable development is a contested domain. We can learn from exploring the way the concept is used and contested.     

我国自然保护区有效管理现状及其分析

本文在对我国１０多个省（自治区）２ｏ多个自然保护区的实际调查和全国资料的统计分析基础上，从我国自然保护区的管理体制、管理机构建设、资源的保护与适度开发利用、科学研究与宣传教育等方面，全面分析了我国自然保护区有效管理的现状，总结了取得的成绩和存在的问题，并针对存在的主要问题，提出了相应的对策与建议。     

论生物多样性的保护问题

当前，任何地区的生物多样性都是自然和社会因素长期综合作用所造成。生物多样性最丰富的地区不一定全部由顶极植被所覆盖，而常常是一些包括所有演替类型的地方。本文通过讨论自然环境的变化和人类生产活动对不同区域景观的影响，探讨有关生物多样性的保护问题。     

世界保护区事业发展的展望

当前,世界130个国家已建立了6500多个保护区,约占地球土地面积4.89％。但是,如何管理好它们,还存在许多问题。本文重点介绍这些问题,并提出一些解决措施,以促进保护区事业的发展。     

东北漫岗区村落的分布特征分析

对黑龙江省绥化市的6个村落、九三垦区鹤山农场的8个村落和嫩江县双山镇的蔡窑村进行实地考察。依据鹤山农场1980-1995年气温、日照时数、风速、降水量和≥5级风日数的气象资料,同时考虑到地形、土壤等因素,分析了东北漫岗区村落分布的特征,即：日照和太阳辐射影响了村落分布的坡向,就不同坡向而言,村落分布数量大小顺序为：东南坡、西南坡、东北坡、西北坡;风影响室温,并可能对房屋造成破坏,故大部分村落分布在坡中部以下;降水量和土壤特性决定了村落的分布下限;地理环境因素和人的选择性、能动性共同决定了东北漫岗区村落呈狭长形沿坡分布。     

对“禁止开发区”规划和管理的几点思考

通过对禁止开发区面临困境和问题的分析探讨,确定了禁止开发区的涵盖范围,并在土地管理、资源保护、财政投资和建设管护等方面提出了相关政策建议,以期为该区的有效管理提供依据。     

我国自然保护区有效管理评价指标研究

本文根据我国自然保护区建设速度较快但管理水平较低的现状，在多年调查研究的基础上，提出制定自然保护区有效管理评价标准的必要性，并详细阐述了在保护区管理条件、管理措施、科研基础和管理成效等四个方面的评价内容，提出１３项评价指标，进而作了详细的评分等级划分，提出一套评价全国自然保护区管理质量的指标体系，为全国自然保护区管理的监督检查提供了一套简便适用、易于操作的评判标准。     

我国自然保护区建设及其对生物多样性的保护

到1991年底,我国共建立各种类型自然保护区708个,总面积56066.6kha,约占国土面积的5.54％。本文从我国森林、草原、荒漠、内陆湿地和水域、海洋、海岸等生态系统类型自然保护区以及野生动、植物类型自然保护区的建设着手,全面分析了我国自然保护区建设对生物多样性保护的贡献和存在的不足。     

Trade-Offs between Species Conservation and the Size of Marine Protected Areas

Abstract:  Moving from single-species- to ecosystem-based management requires an understanding of how community-level attributes such as diversity change with area. We used survey data from bottom trawls to examine spatial patterns of species richness in U.S. Pacific coastal fishes. Specifically, we generated and compared species–area relationships (SARs) for species classified into several groups on the basis of maximum body size, trophic level, diet, maximum depth, geographic affinity, and taxonomic order. Because SARs among groups were not parallel and z values varied significantly for several groups, groups of species were under- or overrepresented (depending on the size of the area) relative to their proportions in the entire community (i.e., entire U.S. Pacific coast). In this way, differences in SARs help demonstrate trade-offs between species representation and coastal area and suggest strategies (such as targeting the protection of habitats and locations where a particular species or groups of species are maximized) that may minimize the size of marine protected areas (MPAs) but protect diversity at the level of the community and functional group.     

2020年全球生物多样性目标解读及其评估指标探讨

2010年以来,全球开展了讨论和咨询,确定世界生物多样性保护的路线图。2010年10月在日本召开的《生物多样性公约》缔约方大会第十次会议通过了《生物多样性战略计划》（2011—2020年）。该战略计划确立了2020年全球生物多样性目标（简称2020年目标）,设计了世界生物多样性保护的路线图和时间表,为制定国家目标提供了灵活的框架。该文剖析了《生物多样性公约》各缔约方对2020年目标的谈判立场,解读了2020年目标的内涵,论述了2020年目标评估指标研究的最新进展,在进一步加强生物多样性评价指标研究、建设生物多样性监测标准和网络、开展生物多样性长期监测方面提出了建议。     

Science, Policy Advocacy, and Marine Protected Areas

Abstract:  Much has been written in recent years regarding whether and to what extent scientists should engage in the policy process, and the focus has been primarily on the issue of advocacy. Despite extensive theoretical discussions, little has been done to study attitudes toward and consequences of such advocacy in particular cases. We assessed attitudes toward science and policy advocacy in the case of marine protected areas (MPAs) on the basis of a survey of delegates at the First International Marine Protected Areas Congress. Delegates were all members of the international marine conservation community and represented academic, government, and nongovernmental organizations. A majority of respondents believed science is objective but only a minority believed that values can be eliminated from science. Respondents showed only partial support of positivist principles of science. Almost all respondents supported scientists being integrated into MPA policy making, whereas half of the respondents agreed that scientists should actively advocate for particular MPA policies. Scientists with a positivist view of science supported a minimal role for scientists in policy, whereas government staff with positivist beliefs supported an advocacy or decision-making role for scientists. Policy-making processes for MPAs need to account for these divergent attitudes toward science and advocacy if science-driven and participatory approaches are to be reconciled.
