In order to reconcile landscape conservation with changing demands on land use and natural resources, it is essential that the ecological, socio-cultural and economic values of the landscape be fully taken into account in planning and decision-making.This paper presents a comprehensive framework for integrated assessment of ecological services and socio-economic benefits of natural and semi-natural ecosystems and landscapes. The framework can be applied at different scale levels to different ecosystems or landscape-units and basically consists of three steps: (1) Function-analysis: translates ecological complexity into a limited number of ecosystem (or landscape) functions, which, in turn, provide a range of goods and services; (2) Function valuation: includes ecological, socio-cultural and economic valuation methods; and (3) Conflict analysis: to facilitate the application of function-analysis and valuation at different scale levels, it is important to integrate analytical valuation methods with stakeholder participation techniques.The framework presented in this paper facilitates the structured assessment of the (total) value of the goods and services provided by a specific area (landscape) and to analyze the costs and benefits involved in trade-offs between various land use options. The last section of this paper gives some conclusions and recommendations for application-possibilities of function-analysis and valuation to achieve more sustainable landscape use and maintenance of our “natural capital”.  相似文献

人类的福祉有赖于自然生态系统所提供的大量的生态系统服务。为此欧盟已经建立了一个名为"自然2000"的大型生态保护区网络;然而,在经历了一段时期的城市扩张和土地使用的集约化后,欧洲的生物多样性已经迅速减少,大多数物种和栖息地的利益仍未处于一个良好的保护状态。在过去的几十年里,可持续旅游概念的提出和以自然为取向的自然型旅游业的出现,作为一项重要的生态系统服务,为保护自然环境和发展当地经济提供了大量的支持。并且这些支持的大部分已经集中投入在了保护区域,但是要看到,在这里我们是假设以自然为取向的旅游业对于尚未被正式保护的荒野环境而言,是一项具有高潜力的保护策略和可持续发展的基础。尤其是在具有多种且相互竞争用途的景观中,它能在自然修复、生物多样性保护和人类活动之间取得一种保证。为了验证这一假设,以位于阿尔加维地区(欧洲西南部)一处与沼泽地带相连的湿地作为研究案例。该案例研究涉及一处重要的但还未处于任何正式保护状态的滨海野生环境,并且20世纪末,在此环境中,几项限制条件促进了创造性的管理模式。描述了在21世纪初,设计并执行一项以自然为取向的旅游设施的过程。这一研究成果以景观生态学的概念框架以及一处涉及修复和保护的环境为支撑。同时文章还探讨了这种基于自然的旅游设施在促进可持续管理和自然保护策略方面的潜在意义。  相似文献

The landscape fulfils many different functions and provides multiple benefits in terms of goods and services for human society. For this reason, it must be conserved in its diversity, complexity and functionality. The aim of this paper is to identify which conditions have to be developed to transform the environmental features of a particular area into a source of income for the local population, and thus to set the basis for conserving natural capital by means of a management process. This opportunity results from a change in the willingness to pay (WTP) declared by the actors potentially interested in the characteristics of a given area. Clearly, modifying the WTP may imply, in some cases, the conservation of a specific site through profit-oriented management. This type of activity allows us to minimize the costs for public agencies as well as to ensure long-term sustainability. We evaluate all of this by means of three different contingent valuation surveys conducted in Sinello Valley, which is located in the north-east of Trentino (Italy).  相似文献

This paper investigates the shared knowledge held by a rural population of the ecosystem services supplied by rural landscapes and woods in the Rome Province of Italy. It is part of a wider research initiative conducted to estimate the non-use values of the same ecosystem services elicited through the contingent valuation method. Our findings demonstrate that: (i) most of the information on ecosystem services comes from a deep-seated community shared knowledge; (ii) some gaps exist between official (scientific/normative) and shared knowledge in the study site; and (iii) stated economic preferences are driven by both consequential motivations, as predicted by the standard economic model, as well as some others. Making explicit the motivational framework behind environmental economic estimates allows one to represent the socio-cultural legacy indispensable for providing a monetary value useful to inform public decision and policies. The use of this approach could contribute to the development of payment for ecosystem services schemes in rural policies affecting common goods.  相似文献

Landscape planning adjusts spatial structures and functions by altering the types of land use / land cover and the patterns of landscapes, and thus further impacts ecosystem services. This paper examines the impacts of landscape planning on ecosystem services and draws the conclusion that the control over the types of land use / land cover, the altering of landscape patterns, and the adjustment of landscape functional characteristics could change the type, quality, and performance of ecosystem services, respectively. Through an overall review on the application of ecosystem service evaluation, spatial mapping, and scenario simulation, this paper further concludes their roles in landscape planning: ecosystem service evaluation provides means to ensure scientific landscape planning; spatial mapping serves as a basis to the decision making; and scenario simulation visualizes all kinds of possibilities for an optimal choice. At the same time, such applications in landscape planning practices, ranging from green space planning, ecological conservation redline planning, land use planning to biodiversity protection planning, are exemplified. Finally, this paper summarizes existing research findings and limitations and proposes that future research is expected to study the relationship between landscape planning and ecosystem services, to build a dynamic composite planning framework that can improve ecosystem services, and to propel the research on the tradeoff-and-synergy among ecosystem services in landscape planning.  相似文献

The establishment of the Common Agricultural Policy has dramatically transformed the relationship between the natural environment and agriculture in the UK. Accordingly, the Government now acknowledges that our stock of ‘natural capital’ is being managed unsustainably and is undertaking Common Agricultural Policy reforms to provide a more sustainable form of agriculture. Such reforms will be based on the economic rationale of payment in return for the provision of natural capital benefits such as biodiversity, carbon sequestration, landscape and recreation. A basic lower tier payment is proposed for general environmental practices, with higher tiers of payments being available for ‘benefit generating’ habitat maintenance and creation.In order to maximise the benefits of such habitat creation, some form of spatial targeting is required. Using geographical information systems (GIS), a suite of spatially explicit criteria are adopted to measure how the potential benefits of native woodland creation vary across the agricultural landscape of the Chilterns natural area. Rather than regarding habitat conservation solely in terms of biodiversity benefits, a more holistic natural capital benefit approach is thus adopted. Public preference on the provision of each benefit is integrated into the GIS-based suitability analysis through multicriteria evaluation. We demonstrate how such a targeted approach leads to large improvements in the delivery of natural capital benefits, with the attainment of biodiversity, landscape and recreation benefits being particularly complementary. As such, the targeted pursuit of natural capital benefits does not compromise the attainment of biodiversity goals, but actually aids in their achievement. However, due to limitations in data availability and accuracy, GIS should be regarded as a decision support tool, with validation of targeted sites being undertaken through a farm audit system.  相似文献

The aim of the paper is to discuss the need for innovation in the landscape policies that were proclaimed by the European Landscape Convention (ELC), which promotes a change from policies stressing conservation to policies stressing a management approach to planning new landscapes. This change focuses on the need to define a new methodological approach to evaluate and promote landscape values as well as to define a process leading to shared values in reference to landscape. This article begins its research with the recent implementation of the ELC in some European Countries. On this basis, it presents an alternative definition of landscape, discusses the role of landscape evaluation, and identifies the different types of values involved in landscape.  相似文献

The ecosystem services approach provides an efficient way to support urban green infrastructure planning. Such an assessment, together with mapping, can effectively produce spatial analyses on a specific scale, helping to maintain multi-functional landscapes and plan urban green infrastructure. In turn, green infrastructure can offer a wide variety of ecosystem services, promoting landscape sustainability. This study develops a methodology for the planning of urban green infrastructure based on an ecosystem services approach that assesses the supply capacity of ecosystem services, and identifies possible spatial characteristic areas for interlinking urban green infrastructure within the study area. More specifically, from a landscape perspective, we use 32 ecosystem services (as X-axis) and different land use types (as Y-axis) to build an ecosystem service assessment matrix. We then take the municipality of Barcelona as an example, using the latter to assess and map ecosystem services within the city through ArcGIS, which shows the spatial distribution characteristics of ecosystem services provision. We identify possible spatial areas - which include ecosystem services provision, barren, and obstructed areas - by overlapping the ecosystem services assessment maps. Ultimately, the results provide a reference for urban green infrastructure planning by recognizing priority protected areas, new construction areas, potential areas, and renewal areas.  相似文献

Through his recent visits to three cities facing severe and challenging living environment, the author had a deeper insight into the symbiosis between human and nature. In Mexico City, the capital of Mexico, urban construction practices against floods and for water supply encroach on natural ecological infrastructure, resulting in the exhaustion of local water resource, city sinking, and erased indigenous cultural landscape of floating gardens. In Dhaka, the capital of Bangladesh, where water bodies are heavily polluted, scarce urban parks become the only refuge for citizens. Finally in Bangkok, the capital of Thailand, estuary gates built to block floods invade the once prosperous canals, accelerating the decline of floating communities and markets and exacerbating traffic congestion and air pollution. Learning from these cases, cities must become better at territorial spatial planning and have the foresight to develop and grow while preserving and improving existing ecosystems. Essentially, territorial spatial planning and ecological restoration is to work with and by nature that would provide generous ecosystem services for humans, and, eventually, to increase people’s well-being and enhance cities’ development of sustainability.  相似文献

基于不同视角与方法的北京市密云区生境规划对比   总被引:1,自引:0,他引:1       下载免费PDF全文
由快速城市化导致的生境破碎化严重影响了生态系统的服务功能。因此,保护与规划城市生境尤为重要。然而目前科学的生境规划设计方法仍有待探索,因为生境的定义具有不同的视角与内涵。基于保护生物学与景观生态学理论,对比了物种视角与景观视角下的2种规划思路,并结合北京市密云区的生境规划,分析对比2种方法的规划结果。在物种方法中,首先选取承担多种生态作用的豹猫为目标物种,运用HSI模型并结合专家赋值法和层次分析法确定每个评价因子的权重,最后通过Arc GIS计算选取高适宜性源地并建立生态网络。景观方法则基于Arc GIS、Guidos、Conefor等软件平台,采用MSPA和景观连通性分析方法,选取重要核心区源地并建立景观生境网络。研究结果表明,2种方法的源地分布差异较大。因此生境规划不能盲目选择一种方法,需有机结合2种方法得到源地与廊道结果。根据地块承载的生境生态功能重要程度确定源地核心保护区,以实现最佳的生境规划和有效的生态系统服务。  相似文献
