生态系统健康研究进展

健康的生态系统一般被视为环境管理的终极目标,进行生态系统健康研究对探索区域与生态系统可持续发展具有重要意义。随着国际生态与健康学会(International Association for Ecology and Health)的解体,生态系统健康研究视角出现转型。系统梳理了近年来国际上有关生态系统健康概念及其评估方法、指标的新进展,通过文献统计和重要文献引用揭示了国际生态系统健康研究的发展历程,提出了从生态系统健康到生态健康再到生态文化健康的三大核心框架发展阶段,生态系统健康的研究对象和范围正在不断扩充。资源环境研究领域是国内研究者应用生态系统健康概念与方法的优势领域,在区域尺度上评价生态系统的健康更贴近资源环境和社会文化交互作用的复合表征理念。因此,我国生态系统健康研究的趋向不仅应包括在生态系统尺度上研究的继续深化,也应包含对生态文化健康概念的完善与应用,并发挥地理-生态视角的区域集成研究优势,从而有效指导区域生态与环境政策制定与实施。     

Paleolimnology: an important tool for effective ecosystem management

Effective management of aquatic resources requires long-term environmental data. However, because long-term observations are rarely available, indirect proxy methods must be used to substitute for these missing historical data sets. Major advances have been made in paleolimnology over the last decade, and many of these advances can be applied directly to integrated and cost-effective assessments of aquatic ecosystem health. This commentary uses the analogy of human health to argue that paleolimnological data provide information crucial to the decision-making processes of ecosystem managers.Keynote lecture, presented at the International Sumposium on Aquatic Ecosystem Health, Waterloo, Ontario, July 23, 1990.     

Challenges Facing the Adoption of Ecosystem Health as a Core Component in Professional Curricula

While there has been considerable success in introducing ecosystem health into professional curricula at a number of universities, there have been significant challenges to its introduction. There are difficulties relating to pervading attitudes within universities. Ecosystem health deals with uncertainty whereas most other disciplines cherish certainty. Ecosystem health is often considered a “soft science” lacking in specifics. The enormity and complexity of ecosystem health problems are often perceived as discouraging and impossible to solve. The university structure can present challenges in that transdisciplinary problem solving requires the participation of many different departments, with several levels of approval required. There are also challenges in the teaching of ecosystem health given its extremely broad focus, limited experience in ecosystem health curricula, and almost no experience in effective evaluation of a field that emphasizes attitudes as much as it does information. This article describes each of these challenges, draws on the experience of the conference, and provides potential solutions to overcoming these challenges.     

Framing the Loss of Solace: Issues and Challenges in Researching Indigenous Compensation Claims

The 2016 judgment in the ‘Timber Creek’ compensation case (Griffiths v Northern Territory of Australia (no. 3) (2016) FCA 900) signals an end to an era of extinguishment-related injustice and inequality, representing, as it does, the first litigated Federal Court award of compensation for the loss or impairment of rights and interests, under the 1993 Native Title Act. In this paper, I explore some of the methodological challenges and conceptual issues confronting anthropologists involved in researching compensation claims. In drawing upon my experience in researching two such claims, I discuss how the issues of gender, resource development, environmental transformation, the Stolen Generation, and the history of Indigenous-European relations in remote and rural Australia impact upon investigations into the loss or diminution of traditional attachments to land. In conceptualising this loss of connection, I discuss material relating to the ‘anthropology of emotions’, and I point to some of the obstacles encountered when talking about emotions cross-culturally. In conclusion, I explore research undertaken into the social and psychological impacts of ecosystem distress, loss of place, and environmental change, and I posit the value of Glenn Albrecht’s concept of ‘solastalgia’ (2005. “Solastalgia, a New Concept in Human Health and Identity.” Philosophy Activism Nature 3: 41–44) in framing research into the loss of solace, and in expanding upon the legal notion of this loss as ‘inconvenience’ and ‘injured feelings’.     

Initiating and promoting the aquatic ecosystem health concept: the Society and the Journal

Since the 1970's the management of aquatic habitats has changed from piecemeal monitoring to the ecosystem approach; this was initiated in the North American Great Lakes, comprising social, economic, and environmental aspects. The information included in this paper is based on the presentation made at the Seminar On Ecosystem Approach To Water Management held in Oslo, Norway during 1991. Recently, the multidisciplinary, holistic, and integrated concept of ecosystem health has emerged, and is being advanced for the implementation of an ecosystem approach to environmental management, which has resulted in the formation of an international society (Aquatic Ecosystem Health & Management Society) and the publication of a primary journal (Journal of Aquatic Ecosystem Health). The information has been updated to incorporate new developments and recent progress about the Society and the journal since the Oslo Seminar.     

An Ecosystem Health Index for a large and variable river basin: Methodology,challenges and continuous improvement in Queensland’s Fitzroy Basin

Report cards are an increasingly popular method for summarising and communicating relative environmental performance and ecosystem health, including in aquatic environments. They are usually underpinned by an Ecosystem Health Index (EHI) that combines various individual indicators to produce an overall ecosystem health “score”. As a result of public water quality concerns, an integrated means of monitoring and reporting on aquatic ecosystem health was needed for the Fitzroy Basin in central Queensland, Australia. The Fitzroy Partnership for River Health was formed to address this need, and developed an EHI and report card for the Basin using existing monitoring data collected from various third parties including regulated companies operations and government. At 142,000 square kilometres, the Fitzroy Basin is the largest catchment draining to the World Heritage Listed Great Barrier Reef. The Fitzroy Basin provides an example of how to deliver an effective aquatic ecosystem health reporting system in a large and complex river basin. We describe the methodology used to develop an adaptive EHI for the Fitzroy Basin that addresses variability, complexity and scale issues associated with reporting across large areas. As well, we report how to manage the design and reporting stages given limitations in data collection and scientific understanding.

Ecosystem integrity in the Great Lakes Basin: an historical sketch of ideas and actions

The concepts of ecosystem and integrity effectively entered the binational political arena in the Great Lakes Basin in the early 1970's. They were brought together explicitly in the statement of the purpose of the 1978 Great Lakes Water Quality Agreement. The 1987 Protocol to that Agreement has helped to specify the practical meaning of ecosystem integrity of the Great Lakes Basin. The proceedings of a binational workshop in 1988, titled An Ecosystem Approach to the Integrity of the Great Lakes Basin in Turbulent Times, helped to clarify the conceptual meaning. An Ecosystem Charter for the Great Lakes-St. Lawrence River Basin was proposed in 1989 to help achieve more thorough implementation of the commitment to ecosystem integrity. The evolutionary emergence of this political concept and related practice is described in the paper.List of abbreviations used in the text CUSIS Canada-U.S. Inter-University Seminar Series - LAA Environmental Lakes Area - EPA Environmental Protection Agency - GLBC Great Lakes Basin Commission - GLC Great Lakes Commission - GLER Great Lakes Ecosystem Rehabilitation - GLFC Great Lakes Fishery Commission - GLSAB Great Lakes Science Advisory Board - GLU Great Lakes United - GLWQA Great Lakes Water Quality Agreement - HASP Heritage Area Security Plan - IBP International Biological Program - IJC International Joint Commission - IZAP Inundation Zone Adaptive Plan - LAMP Lake-wide Management Plan - LLRS Lake Levels Reference Study - MAB Man and the Biosphere program - NEPA National Environmental Policy Act - PLUARG Pollution from Land Use Activities Reference Group - RAP Remedial Action Plan - SCOL Salmonid Communities in Oligotrophic Lakes - SGLFMP Strategic Great Lakes Fishery Management Plan - SPOF Strategic Plan for Ontario Fisheries - UNESCO United Nations Educational, Scientific and Cultural Organization Aquatic Ecosystem Health and Management Society.

Complexity and Human Health: The Case for a Transdisciplinary Paradigm

Transdisciplinary thinking is an emerging philosophy underpinning health social science. We advance a definition of transdisciplinary thinking and link it with complexity theory. Complexity theory's concern with non-linear relationships, interactive causality and emergent properties of systems compels researchers to adopt a transdisciplinary perspective. We construct a generic framework for analyzing health processes from diverse disciplines and apply it to coronary heart disease in the Australian Coalfields. Insights from this analysis support our argument that transdisciplinary thinking maximizes understanding of the complexity of human health.     

Towards Enhancing Community Health in El-Fayoum,Egypt, Using Ecosystem Approaches

Ecosystem degradation caused by factors such as improper natural resources management and contamination with agricultural, industrial, and domestic wastes often results in the creation of an unhealthy ecosystem, a main cause for the prevailing poverty and poor health in many parts of rural Egypt. In collaboration with members of the community in some villages of El-Fayoum province, an interdisciplinary research team is currently employing an ecosystem approach to arrive at an understanding of community health problems with a view to develop resource management interventions and policies aimed at enhancing community health and well-being. Participatory rural appraisal (PRA) and knowledge, attitudes, and practices (KAP) techniques were used to measure the perceptions of the community’s men and women of their health and environmental priorities, and to test their current state of knowledge and awareness of the health-related issues. The results indicate that these perceptions were gender-sensitive and were different from those of Ministry of Health. Spatial and temporal monitoring and assessment of the ecosystem components revealed considerable land and water resources degradation. Presence of water pools and waterways in the vicinity of the residential areas enhanced the risk of water-associated diseases. Although, the disease-carrying vectors of schistosomiasis and malaria were detected in the waterways, the incidence of the two diseases was relatively low in the main village in contrast to the situation in the nearby hamlets. Prevalence of schistosomiasis was substantially higher in these hamlets (20–30% compared to 2–3% in the main village). Such a highly infected community represents a continuous pool of reinfection of the waterways, an issue that needs to be further examined to determine its relation to the hamlets’ specific ecosystem characteristics. A high incidence of hepatitis C and soil transmitted-intestinal parasites were markedly detected. It is concluded that in addition to natural resources degradation, other potential health risk factors were identified including socioeconomic, cultural, and institutional factors. Further studies are being conducted to explore these potential risk factors and their links to human health and well-being.     

What is a healthy ecosystem?

Rapid deterioration of the world's major ecosystems has intensified the need for effective environmental monitoring and the development of operational indicators of ecosystem health. Ecosystem health represents a desired endpoint of environmental management, but it requires adaptive, ongoing definition and assessment. We propose that a healthy ecosystem is one that is sustainable – that is, it has the ability to maintain its structure (organization) and function (vigor) over time in the face of external stress (resilience). Various methods to quantify these three ecosystem attributes (vigor, organization, and resilience) are discussed. These attributes are then folded into a comprehensive assessment of ecosystem health. A network analysis based ecosystem health assessment is developed and tested using trophic exchange networks representing several different aquatic ecosystems. Results indicate the potential of such an ecosystem health assessment for evaluating the relative health of similar ecosystems, and quantifying the effects of natural or anthropogenic stress on the health of a particular ecosystem over time.     

From Multiple Voices to a Common Language: Ecosystem Approaches to Human Health as an Emerging Paradigm

The International Forum on Ecosystem Approaches to Human Health, held in Montreal, May 18–23, 2003, was one product of a new paradigm or framework linking health, ecosystems, and sustainable development that emerged in recent decades. This profile aims to provide a backdrop for the contents of this supplementary issue by outlining some of the key principles of the Ecosystem Approaches to Human Health (Ecohealth) framework. It also discusses some of the activities supported by the Ecosystem Approaches to Human Health Program Initiative of the International Development Research Centre (IDRC) to build on the success of the Forum. In doing so, the intention is to frame the 2003 Forum as one in a series of opportunities to reflect and learn from precedents of research and practice from an ecohealth perspective and to foster the development of a community of practice on Ecohealth (COPEH). The profile not only places the contents of the supplement and the Forum within a larger context, but also provides an overview of other IDRC activities that are building capacity for future research and practice, and are strengthening the emerging COPEH.     

EAM会议专刊辑述评——气候变化下旱区农业生态系统的可持续性

农业生产是将自然资源不断转化为农产品的过程。简单的说就是将阳光、空气、水和土壤等无机资源转化为可以供人类消费的有机产物。农业生态系统必须对全球气候变化、市场竞争、自然环境的恶化、经济等政策法规和人民的需求等因素做出灵活的应对策略,同时还要保证自然生态系统的稳定性。在发展中国家,有超过20亿的人口每天收入低于2美元,他们收入中绝大部分都用于解决温饱。这些人大部分生活在干旱、半干旱地区,并以农业生产作为生活的主要来源。由于这些地区水资源匮乏、土壤贫瘠,粮食安全问题一直是该地区人类生存的关键。中澳两国都把干旱、半干旱地区的农牧业发展作为研究的重点。两国的专家都致力于恢复和维护干旱半干旱地区脆弱的农业生态系统。气候变化正在使农业生态系统可持续发展面临严峻挑战。因此,迫切需要农学,生态学,环境学,社会经济学等多学科的共同发展和融合解决这一问题。2010年7月20—25日在兰州大学举办了以“气候变化和旱区农业生态系统管理”为主题的“第二届生态系统评估与管理（EAM）国际会议”。国内外众多知名专家参与了此次会议,并共同讨论在全球气候变化背景下如何提高干旱半干旱地区脆弱农业生态系统生产力与可持续性。本次会议的议题是：(1）半干旱地区旱作雨养农业生态系统评估与管理,(2）干旱地区绿洲农业生态系统评估与管理。此次会议由兰州大学和澳大利亚西澳大学联合主办,中国科学院生态环境研究中心协办,由国家教育部和国家外专局联合支持、兰州大学干旱与草地生态教育部重点实验室承担的“旱寒生态学”学科创新引智基地和西澳大学农业研究院、FAO属下的叙利亚国际旱地农业研究中心(ICARDA)联合提供资金支持。会议期间,25位专家就干旱、半干旱地区植物土壤互作关系作了报告。另外还有18位在干旱半干旱地区科研一线工作的青年学者汇报了研究进展,并与专家进行了广泛交流。报告会之后,大会组织专家分别对典型旱区农业进行了考察,分别是兰州大学黄土高原旱地农业生态实验站(榆中)和甘肃武威市民勤绿洲农业生态系统。此次大会遴选出35篇学术论文,以专刊的形式发表于《生态学报》第31卷第9期。会议遴选出的其它英文文章将于2011年在《Plant and Soil》和《Crop and Pasture Science》上发表,敬请期待。我们相信,本专刊的出版将会对气候变化背景下旱区农业生态系统的研究和发展产生重要的推动作用。     

Regional ecosystem health response to rural land use change: A case study in Lijiang City,China

Quantitative analysis of the response of ecosystem health to rural land use change is required to comprehend the human-nature coupling mechanism and to explore the process of global environmental change, which can interpret the ecological effects of regional land use and land cover change comprehensively. However, the existing regional ecosystem health assessment largely ignored either the internal connection of ecosystem health to land use patterns or the internal representation of ecosystem services to ecosystem health. Using Lijiang City of China as a study area, the average normalized difference vegetation index (NDVI), landscape metrics, and ecosystem elasticity coefficient based on different land use types were used as quantitative indicators. Then the coefficient of spatial neighboring effect was introduced to characterize the adjacency effect on ecosystem services, and to generate the index of integrated ecosystem health. The results showed the change of land use was close to 30% at county level from 1986 to 2006, and forest land was the primary land use type. With respect to the declining physical health of ecosystems in all the four counties, the integrated health experienced a slight increase in Lijiang County. The vast majority of towns’ ecosystem physical health and integrated health declined, while more than 70% of towns did not change distinctly. Ecosystem physical health had distinct influence on the integrated ecosystem health, and ecosystem vitality was the main factor affecting the condition of physical health. Emphasized in the interconnection of pattern and process, this study provided an ecosystem health approach to assessing the integrated ecological effects of regional land use change.     

A conceptual framework to assess the effects of environmental change on ecosystem services

A new conceptual framework is presented for the assessment of the impacts of environmental change drivers on ecosystem service provision and the policy and management responses that would derive from the valuation of these impacts. The Framework for Ecosystem Service Provision (FESP), is based on an interpretation of the widely-used Drivers-Pressures-State-Impact-Response (DPSIR) framework. FESP differs from the DPSIR by offering clarity in the definitions of the various DPSIR components as well as introducing novel elements of relevance to the ecosystem service approach. The value of a common framework lies in making the comparison across competing services accessible and clear as well as highlighting the conflicts and trade-offs between not only multiple ecosystem services, but also multiple service beneficiaries. The framework is explicit, for example, in recognising as state variables not only the attributes of the Ecosystem Service Providers (ESPs), but also the attributes of the Ecosystem Service Beneficiaries (ESBs). That a service depends as much on the attributes of the people whose well-being benefits from the service as on the attributes of the biology providing the service is an important step in integrated social-ecological thinking. FESP also identifies the mechanisms of either mitigation or adaptation to the environmental change problem through the effect of these response strategies on specific pressure or state variables. In this way, FESP can contribute to the policies and strategies that are used to support conservation management. This paper describes the principles of FESP and presents some indicative examples of its practical implementation.

Conservation Values and Risk of Handling Bats: Implications for One Health Communication

Flying-foxes provide critical ecosystem services, but their role as hosts to zoonotic pathogens may undermine conservation support. We surveyed 214 residents of Cairns, Australia, regarding their perceptions about health risks associated with flying-foxes and support for flying-fox conservation. Greater likelihood of handling a flying-fox was associated with lower knowledge about risks, greater conservation support, and environmental organization membership. Respondents less likely to seek medical attention after a minor scratch tended to be younger, unemployed and perceive lower risk. Individuals who support flying-fox conservation should be one group targeted in One Health communication integrating health and conservation messages.
