自然生态价值、生态资产管理及价值实现的生态经济学基础研究——科学概念、基础理论及实现途径 总被引:1,自引:0,他引:1
自然界的生态系统为人类繁衍发展提供各式各样的生活、生产和生计的环境条件与自然资源。基于自然规律的生态系统管理是人类社会不断认知自然生态价值、保护利用自然环境和资源、创造积累生态资产、维持社会经济系统永续发展的基本途径。以此为核心认知的区域生态经济学或经济生态学,正在成为探讨人类世地球系统演变及社会经济可持续发展问题的科学研究前沿。本文以大尺度区域宏观生态系统科学为学术视角,以生态系统的多功能性与多元价值观为基础,综合论述了自然生态价值、生态资产、生态产品等基本概念;从生态学、社会学和经济学融合角度,分析讨论了生态资产形成与变化、生态产品生产与消费、生态投资与生态资产损益等过程原理;提出了区域生态资产的系统经营与生态价值实现途径,期望为我国及区域生态系统价值及生态资产的评估,生态产业及生态价值实现体系的发展提供理论和方法学参考。 相似文献

E.Higgs 《Restoration Ecology》2005,13(1):159-164
The terms “ecological restoration” and “restoration ecology” are frequently interchanged. Restoration ecology is the suite of scientific practices that constitute an emergent subdiscipline of ecology. Ecological restoration is the ensemble of practices that constitute the entire field of restoration, including restoration ecology as well as the participating human and natural sciences, politics, technologies, economic factors, and cultural dimensions. This paper is motivated by the concern that the broader practice of restoration may become narrowed over the next decade as a result of zealous attention to scientific and technological considerations, and that restoration ecology will trump ecological restoration. Scientific and technological acumen is necessary for successful restoration, but insufficient. Maintaining a broader approach to restoration requires respect for other kinds of knowledge than science, and especially the recognition of a moral center that is beyond the scope of science to address fully. An example of integrated restoration is presented: the ecological and cultural restoration of Discovery Island (near Victoria, British Columbia, Canada) by the Lekwungen people (Songhees First Nation). 相似文献

Recent achievements of computer science provide unrivaled power for the advancement of ecology. This power is not merely computational: parallel computers, having hierarchical organization as their architectural principle, also provide metaphors for understanding complex systems. In this sense they might play for a science of ecological complexity a role like equilibrium-based metaphors had in the development of dynamic systems ecology. Parallel computers provide this opportunity through an informational view of ecological reality and multilevel modelling paradigms. Spatial and individual-oriented models allow application and full understanding of the new metaphors in the ecological context. 相似文献

EcoSummit 2007 was successfully held in Beijing in May 22–27 with a theme of “Ecological complexity and sustainability: the opportunities and challenges of ecology faced by 21st century”. More than 1,400 delegates from over 70 countries and regions and 28 international/regional ecology-related organizations initiated or co-sponsored the summit. 13 plenary keynote speeches, 49 symposiums and 20 organized oral sessions were arranged. A Beijing Ecological Declaration has been adopted and disseminated world-wide with an accompanied title of “A World Role for Ecology: The Key to Life”. The summit shows that global ecological security, regional ecosystem service, and local human ecological health are becoming the three priority issues in the frontiers of world ecology. Ecology, a kind of natural philosophy, system science, engineering instrument and natural aesthetics in dealing with the relationship between Man and Nature, should be and must become the scientific basis for institutional reform, industrial transition, social/economic management and overall decision making. The ultimate goal of understanding, simplification and transformation of complexity is to regulate, conserve and construct a sustainable “Earth Village”. 相似文献

物质流过程是考察系统属性的重要维度。区域物质流分析在研究框架、指标体系、数据集成、管理应用等方面的发展困境,都不同程度地反映了"黑箱假设"以及"系统隐喻"等产业生态学理论的应用局限性。基于整合复杂性科学、广义进化论的生态学组织层次理论,对区域物质流分析开展理论探讨,指出应在原有的"系统"思维之外引入"景观"概念,以拓展区域物质流分析的空间与认知维度。基于"从系统到景观"的理念,将景观生态学原理引入区域物质流分析,建构区域物质流分析的景观取向,并从空间结构与认知图式两个方面对这一取向的核心涵义做以解读。结合区域物质流分析的最新研究案例,从多尺度MFA的综合研究框架、物质流动过程的时空集成研究、物质流动过程的空间行为管理等几个方面,对区域物质流分析的景观取向做了进一步探讨。 相似文献

Habitat transformation is one of the leading causes of changes in biodiversity and the breakdown of ecosystem function and services. The impacts of habitat transformation on biodiversity are complex and can be difficult to test and demonstrate. Network approaches to biodiversity science have provided a powerful set of tools and models that are beginning to present new insight into the structural and functional effects of habitat transformation on complex ecological systems. We propose a framework for studying the ways in which habitat loss and fragmentation jointly affect biodiversity by altering both habitat and ecological interaction networks. That is, the explicit study of "networks of networks" is required to understand the impacts of habitat change on biodiversity. We conduct a broad review of network methods and results, with the aim of revealing the common approaches used by landscape ecology and community ecology. We find that while a lot is known about the consequences of habitat transformation for habitat network topology and for the structure and function of simple antagonistic and mutualistic interaction networks, few studies have evaluated the consequences for large interaction networks with complex and spatially explicit architectures. Moreover, almost no studies have been focused on the continuous feedback between the spatial structure and dynamics of the habitat network and the structure and dynamics of the interaction networks inhabiting the habitat network. We conclude that theory and experiments that tackle the ecology of networks of networks are needed to provide a deeper understanding of biodiversity change in fragmented landscapes. 相似文献

Resource and energy efficiency are key strategies for production and recycling networks. They can contribute to more sustainable industrial production and can help cope with challenges such as competition, rising resource and energy prices, greenhouse gas emissions reduction, and scarce and expensive landfill space. In pursuit of these objectives, further enhancements of single processes are often technologically sophisticated and expensive due to past achievements that have brought the processes closer to technical optima. Nevertheless, the potential for network‐wide advancements may exist. Methods are required to identify and assess the potential for promising resource and energy efficiency measures from technical, economic, and ecological perspectives. This article presents an approach for a material flow‐based techno‐economic as well as ecological analysis and assessment of resource efficiency measures in production and recycling networks. Based on thermodynamic process models of different production and recycling processes, a material and energy flow model of interlinked production and recycling processes on the level of chemical compounds is developed. The model can be used to improve network‐wide resource efficiency by analyzing and assessing measures in scenario and sensitivity analyses. A necessary condition for overcoming technical and economic barriers for implementing such measures can be fulfilled by identifying strategies that appear technologically feasible and economically and ecologically favorable. An exemplary application to a production and recycling network of the German steel and zinc industry is presented. From a methodological point of view, the approach shows one way of introducing thermodynamics and further technological aspects into industrial planning and assessment. 相似文献

Our article uses the theory of transaction cost economics as a conceptual basis for examining the contracting mechanisms by which firms in the computer industry structure programs to encourage their suppliers to improve their environmental management systems and/or the environmental quality of their products. We explore the economic transactions hazards associated with asking suppliers to invest in the specialized technologies required to improve environmental performance of products and management practices and the relational contracting mechanisms computer industry firms are using to protect themselves against these hazards. We also describe the importance the managers we interviewed attributed to various transactions hazards and their perceptions of how well their firms were coping with them. We conclude by discussing questions for future research. By using TCE to frame our analysis of how computer manufacturers are structuring their relationships with their suppliers in the environmental area, we hope to show how social science theory can be used to enrich and increase the practicality of the work done by engineers and others in the mainstream areas of the industrial ecology field. 相似文献
