泰山保护地生态资产价值评估

为进一步加强自然保护地生态资源的保护,促进区域更好地发挥其生态系统服务功能,进行生态资产价值衡量具有重要意义。实现对保护地生态资产及价值的评估,明确自然保护地的生态保护价值,可以为保护地生态功能定位以及生态环境的建设和保护提供重要的科学依据。泰山因其独特的地理位置和生态条件,有着丰富的自然生物资源,构成了独特的自然生态系统,具有重要的生态学研究价值。研究选取泰山保护地内的生态资产为研究对象,基于文献调研、观测与统计资料等相关数据,从物质量与价值量的角度进行模型运算,得到2017年泰山保护地生态资产价值为133908万元。研究结果表明泰山生态资产价值对维持当地可持续发展具有举足轻重的作用。本文构建的评估体系为我国生态资产价值的评估提供了一个相对全面的综合评估方案,为我国生态资产评估提供更为全面的科学依据与决策支持,也为环境产权、生态补偿等政策制定提供定量分析基础。     

黔东南苗族侗族自治州生态保护成效评估

评估一定时期内自然生态系统调节服务功能价值的变化,可体现区域生态保护的实施成效。贵州省黔东南苗族侗族自治州位于我国西南喀斯特地区,森林覆盖率高,是长江、珠江上游的重要生态屏障。以黔东南州为案例,构建了基于生态系统生产总值的评估指标体系,并运用生态系统调节服务价值核算的技术方法,探讨了将生态系统生产总值核算应用于生态保护成效的评估。结果显示,黔东南州2010年生态系统生产总值调节服务价值为2238.78亿元,是当年GDP的7.16倍;重点生态功能区县的单位面积和人均调节服务价值均高于非重点生态功能区县。2000—2010年,黔东南州生态系统生产总值调节服务价值以不变价计算增幅为2.26%;非重点生态功能区县的增幅高于重点生态功能区县。研究表明,生态系统调节服务价值核算可以直接反映黔东南州一定时期的生态环境状态和变化,体现生态保护建设工程综合实施效果,为黔东南州后续生态保护建设提供科学依据。     

野生动物类型自然保护区保护成效评估研究进展

野生动物类型自然保护区是以野生动物种群及其生境为主要保护目标的自然保护区,开展野生动物类型自然保护区保护成效评估,对促进野生动物资源的科学保护、自然保护区的有效管理和宏观规划具有重要的指导意义。本文对自然保护区评估(包括保护价值、管理有效性、人为影响等评估)和野生动物保护成效评估等方面进行了系统的论述,明确了野生动物类型自然保护区保护成效评估的概念和内容,强调了保护成效评估中时空动态变化的重要性,指出了现有研究中存在的问题,建议在未来的保护成效评估研究中,应注重自然保护区内目标物种种群和生境动态、巡护与监测有效性的评估。     

自然保护地保护成效评估: 进展与展望

自然保护地(protected areas)保护成效是指自然保护地对主要保护对象的保护效果, 及其在维持生物多样性和保障生态系统服务功能等方面的综合成效。近年来自然保护地保护成效评估逐渐成为国内外的研究热点之一。 本文分别从不同空间尺度、评估对象、评估方法以及评估指标等方面综述了相关的研究进展。总体来看, 近年来的研究已基本覆盖了全球、区域、国家和单个自然保护地等不同尺度, 针对森林、湿地、草地和荒漠等代表性生态系统以及野生动植物等主要保护对象进行了评估, 发展了“matching”技术等更为有效的分析方法, 探索了系统的自然保护地保护成效评估指标体系, 并应用一些指标进行了保护成效的案例研究。自然保护区(nature reserve)是我国自然保护地的主体, 近年来我国自然保护区相关管理部门也相继开展了保护成效评估工作, 建议未来进一步加强自然保护区网络尺度和各类型自然保护区的保护成效评估研究, 将自然保护区保护成效评估与管理评估相结合, 研究自然保护区保护成效面临的新问题和潜在影响, 为提升我国自然保护区管理质量提供科学依据。     

光核桃遗传资源的经济价值评估与保护

本文将光核桃遗传资源的经济价值划分为直接利用价值、间接利用价值和潜在利用价值,采用市场价格法、旅行费用法、防护费用法及类比分析法等方法对光核桃遗传资源的经济价值进行估算,并提出该资源保护与管理建议。光核桃遗传资源经济价值的评估,将为具有潜在巨大经济价值的生物遗传资源管理提供价值评估方法,同时为维护国家利益、制订生物多样性保护与管理政策及建立生物遗传资源惠益分享制度提供技术支持。     

我国东北三省自然保护区物种保护价值评估

自然保护区作为保护生物多样性最主要的手段之一,得到了世界各国的重视。如何科学客观地评价自然保护区的保护价值,并依据保护价值对其进行分类管理是当前我国自然保护区建设与管理的重要课题之一。以我国东北地区40个国家级自然保护区为研究对象,分别对其物种多样性保护价值和遗传种质资源保护价值进行了评估。通过选取物种的濒危性、特有性和保护等级等指标来计算野生动植物的多样性保护价值;选取分类独特性、近缘程度和濒危性等指标来计算遗传种质资源保护价值,进而计算出各自然保护区的综合物种保护价值。研究结果显示:该评价方法能够很好的反映自然保护区生物多样性及其各个层次和类群的保护价值,能够较准确地识别其物种保护优先性。不同自然保护区其保护价值存在一定差异;同一自然保护区中野生动物与植物之间的物种多样性保护价值没有显著差异,但其野生动物与植物之间的遗传种质资源保护价值存在一定差异性;绝大多数自然保护区其植物遗传种质资源保护价值大于动物遗传种质资源保护价值;虽同为国家级自然保护区,其综合物种多样性保护价值差异很大。吉林长白山国家级自然保护区、吉林珲春东北虎国家级自然保护区、吉林松花江三湖国家级自然保护区的综合保护价值显著高于同类型的其他自然保护区,而辽宁章古台国家级自然保护区、黑龙江双河国家级自然保护区和黑龙江三环泡国家级自然保护区的综合物种保护价值较低,不同类型自然保护区之间其综合保护价值则没有明显差异。该评价方法能较好地进行自然保护区物种保护价值评价,并用于进行自然保护区之间的比较,并不会因自然保护区所处生境、所分布物种不同而产生评价结果上的偏差;该方法在对自然保护区遗传种质资源部分的计算方面需要进一步完善;总体上来说该评价方法不会因自然保护区类型的不同产生差异;今后在对东北地区自然保护区管理分类研究中可将此评价结果作为参考,并作为评价该地区自然保护区能否晋升为国家级自然保护区的辅助工具。这在一定程度上减少了人为主观性,具有较大可行性。     

传粉昆虫物种多样性监测、评估和保护概述

欧洲和北美等国相继建立起传粉昆虫物种多样性监测和评估体系。基于传粉昆虫的监测资料,能够对欧美部分区域和某些传粉昆虫类群的现状、下降程度以及影响因素进行研究。欧洲和北美等地已开展部分传粉昆虫保护措施和项目,如欧洲部分国家实施的＂农田环境计划＂项目（Agri-Environmental Schemes）能够保护农田生态系统中传粉昆虫的栖境,恢复和提高传粉昆虫物种多样性。我国传粉昆虫物种多样性十分丰富,但目前还没有一个以监测和评估传粉昆虫物种多样性为主的平台,也未对某区域或某类群传粉昆虫多样性的变化进行评估,传粉昆虫多样性的保护也未引起足够重视。为了解我国传粉昆虫物种多样性现状及变化情况,作者建议在我国建立传粉昆虫物种多样性监测和评估体系,以提高我们在该领域的认识水平,并为开展相应的保护工作提供理论基础。     

基于DNA条形码评估西双版纳国家级自然保护区对樟科植物进化历史的保护

为评估西双版纳国家级自然保护区对樟科这一重要植物类群进化潜力的保护情况, 揭示将物种进化历史纳入生物多样性保护评估的重要性, 本研究通过对西双版纳地区长期的野外调查并查阅标本记录与文献资料, 整理出该地区樟科13属121种物种的具体分布信息, 以植物条形码ITS序列作为分子标记构建了反映整个西双版纳地区樟科植物系统发育关系的系统发育树。我们以此为基础, 从物种层面分析了各物种的进化特异性(evolutionary distinctiveness, ED), 从区域层面分析了自然保护区内、外以及32个行政乡镇的系统发育多样性(phylogenetic diversity, PD), 并结合物种丰富度(species richness, SR)与物种濒危等级, 综合探讨了西双版纳国家级自然保护区对樟科植物进化历史的保护情况。研究发现, 西双版纳国家级自然保护区仅拥有整个西双版纳地区54.5%的樟科物种数, 却保护了该地区樟科植物约88.8%的进化历史, 没有被列入保护范围但却拥有高系统发育多样性的区域有打洛镇、易武乡等。就物种而言, 进化特异性相对较高的19个物种中, 有5种(26.3%)在自然保护区内没有分布; 濒危等级高的54个物种中, 有20种(37.0%)在自然保护区没有分布, 同时拥有高进化特异性和濒危等级的物种仅有1种不在保护区内分布。结果表明, 虽然西双版纳国家级自然保护区对樟科这一植物类群的系统发育多样性以及高保护价值物种的保护较好, 但仍有部分重要樟科植物的进化历史没有涵盖在现有自然保护区范围内; 按照传统方法设定的自然保护区虽能在一定程度上保护樟科物种的进化历史, 但仍然存在与标准化系统发育多样性保护策略相矛盾的地方。因此, 今后在建立自然保护区时, 应将系统发育多样性考虑在内, 以保护生物多样性应对环境变化的潜力。     

生态保护项目绩效评估的技术方法体系

自20世纪90年代以来,以各种形式的生态补偿政策和工程项目为代表的生态保护项目在全球广泛实施。1998年长江大洪水之后,我国也陆续实施了天然林保护工程、退耕还林还草工程、京津风沙源治理工程、森林生态效益补偿基金、退田还湖还湿工程、生态转移支付等一系列生态保护项目。近年来,政府、研究人员和社会各界越来越重视这些项目产生的生态、经济和社会效益。不过,我国生态保护项目绩效评估还处于起步阶段,主要体现在定量化不足、研究设计不严密、基准线选取不规范、评估方法过于简易、因果推理证据不足、评估结果可信度较差。不管是从学术研究、国家战略,还是实际生态管理的角度,都迫切需要推动和完善我国生态保护项目的绩效评估。结合过去十多年的理论和案例研究经验,对绩效评估的研究设计、基准线选取、评估方法、以及评估分析中面临的问题和挑战进行了系统地归纳与梳理,以期为进一步开展生态保护项目绩效评估提供技术参考。     

Biography of a "Feathered Pig": The California Condor Conservation Controversy

In the early 20th century, after hundreds of years of gradual decline, the California condor emerged as an object of intensive scientific study, an important conservation target, and a cultural icon of the American wilderness preservation movement. Early condor researchers generally believed that the species' survival depended upon the preservation of its wilderness habitat. However, beginning in the 1970s, a new generation of scientists argued that no amount of wilderness could prevent the condor's decline and that only intensive scientific management - including captive breeding - could save the species from certain extinction. A bitter and highly politicized battle soon developed over how to best preserve the condor. For 5years the condor was extinct in the wild; however, by the time that officials released the first captive-bred birds the condor recovery program had garnered widespread public support, even among its former critics. Today, condor advocates from the scientific and activist communities work together to manage the species and protect its habitat. The condor's story illustrates some of the tensions, problems, and successes that have accompanied the rise of conservation biology as a scientific field and environmental movement in the United States.     

中国履行生物多样性公约的成就和展望

2004年是生物多样性公约实施10周年。中国于1993年1月7日作为第7个国家正式加入“公约”。接着就由国家环境保护总局牵头组建国家履约协调组和许多联络点,下设办公室负责日常工作。可见,国家对生物多样性工作的重视和认真的态度。10年来,中国在履约方面做了大量工作,成绩显著。例如,完成了“中国生物多样性国情研究报告”和“中国生物多样性保护行动计划”等一大批重要文件,建立了“生物多样性委员会”、“生物多样性保护基金会”和相应的科学与教育部门,开展了许多科研项目和讲授相关的课程,出版了系列丛书和“中国生物多样性”学术刊物,重视开展学术交流,建立了生物多样性数据库和相关的管理政策,生物多样性保护实体和产业日益增加和发展等就是明显的事例。履约10年的经验在于下列三个方面(1)保护和发展必须密切结合;(2)“统一协调、分散管理”的方针需要进一步完善;(3)基础性和综合性研究需要加强。展望未来,只有在加强基础和综合研究以及提高管理水平方面下一番功夫,履约工作才能取得更大的成绩。     

White coat hypertension and haemostatic/fibrinolytic balance disorders

White coat hypertension (WCH) or isolated clinic hypertension is generally accepted to be a benign condition, although some reports have suggested that it may be associated with an increased cardiovascular event rate or other cardiovascular alterations. It has been previously shown that essential hypertension (EH) is associated with abnormalities in haemostatic/fibrinolytic balance and endothelial function. The aim of our study was to assess the impact of WCH on fibrinolytic balance and endothelial function by measuring plasma levels of plasminogen activator inhibitor-1 (PAI-1), tissue plasminogen activator antigen (tPA), fibrinogen, and thrombomodulin. These markers were determined in 71 patients with EH, 26 with WCH and 87 normotensive healthy control subjects. The three groups were not different with respect to age, gender, smoking habits, BMI and blood lipids. Subjects with WCH were found to have increased plasma levels of PAI-1, tPA, fibrinogen and thrombomodulin compared to controls, but less compared to hypertensive ones. Our results suggest that WCH may be associated with decreased fibrinolytic potential and endothelial dysfunction, indicating that WCH may not be a completely harmless trait.

Plant Conservation Challenges in the Bahama Archipelago

The Bahamian archipelago has a rich flora with 89 endemic species. An international symposium held at Nassau in October 2012 to celebrate the 30th anniversary of the publication of the “Flora of the Bahama Archipelago” provided a forum to discuss plant conservation issues on these islands. This article builds on conclusions from this symposium and results from joint plant conservation research projects among the authors. The two main conservation challenges for these islands are: (1) environmental uncertainties derived from global warming and associated sea level changes and (2) the need for increased plant conservation awareness among the predominant urban population of the archipelago. Legal tools and biodiversity international agreements in place for The Commonwealth of the Bahamas can facilitate mechanisms for effective plant conservation. Further legal developments need to be established in The United Kingdom Overseas Territory of The Turks and Caicos Islands. There is an urgent need to redevelop the Botanic Garden of Nassau and designate it as the national botanic garden of The Bahamas. Further research related to the taxonomy, biology, conservation status, and distribution of the endemic species is urgently needed. Research initiatives pertinent to the detrimental effect and biology of invasive species are also lacking. The heterogeneous environments and uneven distribution of human populations across the archipelago are major challenges for conservation. Finally because of the political and economic status of The Bahamas and The Turks and Caicos, conservation agencies from the archipelago do not have easy access to international or British/European Union funds for global conservation initiatives.     

The Distribution, Status, and Conservation Outlook of the Drill (Mandrillus leucophaeus) in Cameroon

The populations of many endangered species are becoming increasingly fragmented, and accurate, current information on the status of these subpopulations is essential for the design of effective conservation strategies within a human-dominated landscape. The drill (Mandrillus leucophaeus) is one of the most spectacular and endangered primates in Africa, yet up-to-date information on its distribution, population status, and conservation outlook is lacking. Cameroon has been estimated to encompass 80 % of the species’ range. We examined the distribution, population status, and conservation outlook for the drill throughout its historic range in Cameroon. To do this, we divided the historic range of the drill in Cameroon (46,000 km²) into 52 survey units along natural and manmade boundary features. Based on a series of field surveys in 2002–2009, village interviews, analysis of geospatial data, and bibliographical research, we assigned each survey unit a rank of 0–4 for 15 parameters indicative of current situation for drills, habitat suitability, and conservation outlook. We obtained direct evidence for the presence of drills in 16 of the 52 survey units, with those of Ejagham, Korup, Ebo, and Nta Ali receiving the highest index scores. We warn of local extirpations and increased isolation among drill populations due to loss of dispersal corridors, e.g., Douala Edea survey unit. In some cases drills persist in forest fragments within human-dominated landscapes, e.g., Kupe-Manenguba, but the species’ future is probably dependent on effective wildlife management in a handful of isolated strongholds where probability of long-term protection is higher, particularly in Korup National Park, Takamanda National Park, and the proposed Ebo National Park. Pressure from current and proposed large-scale commercial plantations, oil prospecting, logging, and the continual human population growth in this region means that a concerted conservation effort will be needed to safeguard the remaining drill habitat if the species is to survive in Cameroon.     

A Revised Conservation Assessment of Dipterocarps in Sabah

Borneo has experienced a rapid decline in the extent of forest cover, which has reduced the amount of habitat available for many plant and animal species. The precise impact of habitat loss on the conservation status of dipterocarp trees is uncertain. We use three contrasting techniques, the extent of occurrence, area of occupancy and ecological niche models derived using maxent , in conjunction with a current land‐use map of Sabah, to derive estimates of habitat loss and infer a regional IUCN Red List conservation status for 33 Sabah dipterocarp species. Estimates of habitat loss differed significantly according to the methods employed and between species on different habitat types. Proportion of habitat loss determined from the ecological niche models varied from 21 percent for Shorea micans to 99.5 percent for Dipterocarpus lamellatus. Thirty‐two of the 33 dipterocarp species analyzed in this study would have their Sabah populations classified as Threatened (equal to a habitat loss of > 30%) under the A2 IUCN Red List criterion. Dipterocarps that occur in lowland forests have experienced greater habitat loss than upland/lower montane or ultramafic species. In addition, species with the lowest predicted area within their historic distributions had the highest proportion of habitat lost, which provides a rationale for targeting conservation effort on the species with narrow distributions. We recommend the ecological niche modeling approach as a rapid assessment tool for reconstructing species’ historic distributions during conservation assessments of tropical trees.     

典型极小种群野生植物保护与恢复技术研究

极小种群野生植物是急需优先抢救的国家重点保护濒危植物。目前,有关极小种群野生植物濒危原因及相应解濒技术的研究还非常缺乏,已有的植物种群生态学和保护生物学理论对极小种群植物并不完全适用,迫切需要研发有针对性的科学理论和保育技术。介绍了国家重点研发计划项目"典型极小种群野生植物保护与恢复技术研究(2016YFC0503100)"的研究意义、内容、目标及展望。项目拟针对典型极小种群野生植物开展保护与恢复技术的研究,拟构建极小种群野生植物的种群生态学和保护生物学理论体系,研发极小种群野生植物保护和更新复壮的技术体系,并建立相应的应用技术标准和示范基地,为极小种群野生植物的保护与可持续利用奠定坚实的理论基础和技术支撑。     

From Reintroduction to Assisted Colonization: Moving along the Conservation Translocation Spectrum

Translocation, the intentional movement of living organisms from one area to another is increasingly being used as a conservation tool to overcome barriers to dispersal. A dichotomy exists for conservation‐oriented translocations: on one hand, there are those that release plants or animals into known historic ranges and on the other hand, there are releases outside historic distributions. Misuse of or attempts to redefine established terms and a proliferation of variants of new terms such as assisted colonization, confuse and hamper communication. The aim of this opinion article is to describe and define a conservation translocation spectrum, from species reintroductions to assisted colonization, and beyond, and in so doing provide a standard framework and terminology for discussing translocation options. I suggest that we are moving along this spectrum, away from the dictates of historical species distribution records, toward the inclusion of more risky interventions that will be required to respond to habitat shifts due to anthropogenic impacts. To some extent rapid climate change changes everything, including how we should view introductions versus reintroductions. We need to seriously consider adding other approaches to our conservation toolbox. Assisted colonization will start us along this path, acknowledging as it does the accelerated rate of habitat change and the problems of attempting to preserve dynamic systems. The next step along the conservation translocation spectrum may be for reintroduction biology and restoration ecology to more comprehensively join forces on carefully selected projects to use species introductions to create novel ecosystems through active ecological community construction.     

关于“生态保护和建设”名称和内涵的探讨

主要针对在生态保护和建设方面用词和理解上存在的差异,着重对其范畴和内涵进行了详细的分析,提出生态保护和建设与环境保护之间既有紧密联系,又有明显差别,宜于分开并列为两个领域。生态保护和建设领域宽广,内涵丰富,不仅要面对各种自然生态系统,也要面对人工生态系统以及多种生态系统复合的景观、区域和全球层次的生态问题。建议在当前情况下可以把"生态保护"和"生态建设"在不同需要的场合分别使用,也可为全面表述而合并使用。
