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

生态系统服务从产生到使用是一个动态流动过程,分别对应着生态系统服务的供给与需求,然而在城市化过程中,人口的聚集及绿色基础设施的破碎导致城市生态系统服务供需失衡极为严重。当生态系统服务供给无法满足需求时,则存在生态系统服务额外需求。通过量化评估生态系统服务的额外需求,将为绿色基础设施的精确供给提供决策依据。以武汉中心城区为例,以街区作为基本单元,选择合适的环境质量标准作为额外需求阈值,对以下4项生态系统服务额外需求进行量化评估与空间制图:空气净化、雨洪调节、温度调节和游憩服务,并采用熵值法求得各项服务的权重,叠加得到综合的生态系统服务额外需求。最终评估结果可作为武汉中心城区绿色基础设施优先实施区域与类型的规划依据。  相似文献

With the formation of the Conservative–Liberal Democrat coalition government in 2010, the funding of local government in the UK changed fundamentally. Through an austerity approach to development, local planning authorities (LPAs) have been required to make significant budgetary savings, raising questions over what services are legally and morally dispensable. One service severely impacted has been green space (green infrastructure) management. In many locations, this has generated negative responses, as the proposed cuts are perceived as decreasing the liveability of urban areas. In response, LPAs are engaging in an examination of how they can manage development to more effectively fund green infrastructure provision. Such debates draw on a range of options from public, private and community funding sources, creating further complexity within LPA financing. To explore these options, this paper discusses the appropriateness of different funding mechanisms proposing a multi-option approach for the long-term management of green infrastructure.  相似文献

Landscape ecology challenges the urbanisation processes and the activities of the infrastructure sectors. Infrastructure networks have a strong impact on the development of cities and landscapes. This impact is often positive in an economic sense but can be negative in respect of natural or recreational functions of city and countryside. The challenge for spatial planning is to locate infrastructure lines in order to safeguard the conditions for the less dynamic functions in and around the urban regions. This paper analyses the impact of network patterns on urban development patterns and on green patterns, taking the history of the Randstad Holland as an example. In history the central peat area of this region was hardly accessible. This fact has led over the course of time to a unique spatial pattern: the major infrastructure lines and the major urban settlements are situated on the rim of a Green Heart. This creates a high-quality setting for the economy and the urbanisation of more than 6 million people as well as for natural and agricultural functions. Such a combination of urban elements and infrastructure around a green core can also be found on other scale levels and in other regions. Constraints on access often correlate with restricted urbanisation and with a sustainable position for the green elements. In those cases that such a restraint is chosen deliberately, often five phenomena are visible: (1) Polarity: a spatial polarity between less dynamic and more dynamic functions. (2) Decentrality: a side position of the main infrastructure and urban centres and a central position for the green functions. (3) Equality: equilibrium in extension of urban and rural elements. (4) Continuity: the green areas are part of larger scale networks. (5) Formality: planning policies couple the planning of infrastructure and dynamic urban activities to the development of the less dynamic, green functions.Together, these five elements create a special approach of spatial planning that can be applied on various scales. It is possible to use these elements as a concept, a design tool to create sustainable conditions for the ‘green’ functions in and around city regions. Based on some examples, suggestions are made for a strategy for urban-rural (re-)development aiming at high-quality urban life and for the natural environment, in and around urban regions. Sustainable spatial patterns demand a planning approach that combines the planning of infrastructure and urban activities with the planning of their green counterpoint.  相似文献

Urbanization poses both challenges and opportunities for the management of urban ecosystems globally. In the Greater Montreal Area (GMA), a major North American urban area where green infrastructure (GI) implementation is in its early stage, there are challenges in maintaining provision of ecosystem services due to urban expansion and climate change impacts. In response, stakeholders in the GMA are trying to further integrate the GI concept into planning practices and have participated in focus groups to discuss various approaches to implementing the GI concept. This paper addresses stakeholder perceptions of the opportunities and obstacles related to natural ecosystem management in the GMA. We discuss the way in which participants perceive the prospect of the GI concept to influence discourse and policy about environmental planning. We found plural perspectives on GI yet there was a broad consensus regarding problems in bringing planning tools in line with socio-ecological processes. This research provides a novel contribution by showing how the concept of GI informs narratives about metropolitan green space and environmental planning. The narratives of most research participants emphasised: 1) that efforts to protect and enhance the urban ecosystem should be approached within a coherent social and ecological framework at the scale of the metropolitan area, and 2) that GI planning needed to rely on collaborative and participatory approaches to enhance ecosystem services at all scales of the GMA.  相似文献

The current rapid urbanization leads to a degeneration in natural ecosystems whose regulating, purification, and production services have been seriously damaged. Landscape architecture focusing more on landscape functions and processes in this context is significant to urban environment improvement, by creating more urban parks and green spaces to provide ecological services as benefits rather than cities' burdens. Therefore, Yu Kongjian defined Designed Ecology as a constructed ecosystem or a system of interactions between living creatures (including human beings) and nature by human design, also ecological processes formed by landscape architecture and planning, and an interdisciplinary, cross-scale, and empirical research in a form of landscape. This research examined the landscape performance of saline-alkali soil amelioration in Qiaoyuan Park designed with the Designed Ecology principles by ecological experiments. The results prove that through micro-topography design, the park's constructed ecosystem significantly drains away salt and alkali to the lower areas of the site, both within the pond and across the whole pond system, achieving its design goal. This case study provides models for similar ecological landscape design of urban parks and green spaces.  相似文献

Emerging shortages of community sporting facilities in Australian cities have led to calls for increased provision of playing fields through public park and open space planning processes. Drawing on a broad literature review and a specific case study of metropolitan Perth, this paper evaluates the value of organised sport as a function of contemporary public parks before proposing policy and practice to ensure that such an increase complements broader urban planning agendas. An analysis of the evolution of public park planning shows that, while the provision of organised sport was the primary function of public parks in the middle of the twentieth century, contemporary park planning is characterised by the embrace of broader ecological planning concepts such as green infrastructure and ecosystem services. These broader concepts are then applied to understand the value of organised sport held within public parks, including its unique benefits and notable limitations when considered alongside other forms of outdoor recreation. With these limitations in mind, this paper concludes by identifying existing and future policy and practice that can help to ensure that demand for community sporting facilities in new residential areas can be met in a manner that complements this ecological role for local parks.  相似文献

以解构增长主义主导下的城市空间增长现实境况为研究背景,针对当前城市空间增长的设定路径在应对生态服务功能的确定性和偶然扰动的不确定性方面所扮演的双重“被动防御”角色,通过韧性与绿色基础设施的概念结合,重构基于绿色基础设施设定城市空间增长的韧性进程:将绿色基础设施视作城市空间增长刚性约束的绝对前提;在此基础上,根据城市空间增长同生态服务功能的适应状况,提供多种弹性引导的空间选择而非限制选择,以此实现“刚性约束同弹性引导的共轭协同”这一空间管控的核心目标,并促使已有设定路径由“被动防御”向“主动反制”的角色转变.基于上述理论框架,组合绿色基础设施评价与最小累积阻力建构GIA-MCR城市空间增长模型,诠释“刚性约束同弹性引导的共轭协同”在技术方法层面的具体落实.杭州的应用研究表明:由该模型设定的城市空间增长能够精准避开中高生态服务功能区域、有序引导城市开发在适宜空间范围内展开;该模型可辅助城市开发边界等空间管控的规划决策支持并配套相应政策工具,以此建立以“空间一张图”为核心的城市空间增长实施管理体系.  相似文献

Green space is an important component in urban environment, providing considerable ecosystem services to our socio-economic-cultural activities. Metrics designed to capture green space provision, supply and demand, measuring availability, accessibility, and visibility have been widely adopted to gauge progress toward achieving sustainable development goals from local to regional scales. In this article, we offer eight reflections on quantitative studies of urban green space for mapping, monitoring, modeling, and management (4M) practices in landscape design and planning. The article’s objective is to stimulate fresh and innovative thinking in the conversion of data to interventions. Eight points are made: 1) Green space mapping should be characterized in a multi-attribute conceptual model, including quantity, quality, type, and structure; 2) green space mapping sources, methods, and uses vary by definitions, approaches, and scales; 3) phenology modifies seasonal quality and quantity of urban green space; 4) spatial and temporal green space data cubes will help realize the goal of near real-time monitoring of urban green space change; 5) green space coverage reveals green space supply, but green space exposure can capture effective demand via modeling the supply–demand relationships of human–green space; 6) green space exposure measures should account for spatial, temporal, and social differences; 7) greening optimization by landscape architects and planners should consider both biophysical, biodiversity, and health benefits; and 8) urban green space management should be strategized with a long-term view. Finally, we advocate data–science–decision support systems that can help guide and promote 4M practices of urban green space. These points of reflection have broad implications for research, practice, and theory of urban green landscape design, planning, and management, and altogether constitute a set of principles that can guide scientists, policy makers, and practitioners toward strategizing optimal 4M of urban green space.  相似文献

A key challenge for research and practice is to understand how the ecosystem approach can be rolled out in spatial planning, management and decision-making. Any framework used to apply the ecosystem approach needs to not only be environmentally coherent but also socially meaningful. Drawing on semi-structured interviews and case studies, this paper examines the potential role of one place-based approach, landscape character assessment, as a medium to ensure socio-ecological relevance in operationalising the ecosystem approach. Our findings show that although place-based approaches have value as frameworks for distilling the ecosystem approach into a manageable form, their ecological relevance is a subject of debate. However, the potential relationship between landscape character, function and ecosystem services presented a powerful pathway for operationalising the ecosystem approach. The ecosystem approach may, in turn, complement landscape character assessment by providing a framework for exploring the functional dimension of landscape condition.  相似文献

县域景观游憩服务评价——以四川省武胜县为例   总被引:2,自引:0,他引:2  
游憩发展潜力是乡村振兴的重要维度,系统评价区域游憩服务并将其用于土地利用决策是引导区域可持续发展的重要策略。 以四川省贫困县武胜县为例,尝试从县域尺度对游憩服务进行建模与制图评价,从游憩吸引力和游憩使用度两个维度对县域游憩资 源进行系统评价,并分析其空间异质性。结果显示,高吸引力 - 高使用度的游憩服务主要集中于人口密度较高、具有特色景观的城 镇中心及其周边;河流沿线属于高吸引力的游憩服务区,具有开发潜力;县域景观中近四成面积不具有游憩开发的价值。县域游憩 服务的评估与制图既是描绘生态系统对人类福祉重要性的有效手段,又为规划设计决策提供依据,是区域可持续发展前瞻评价。  相似文献

The physical appearance of the Netherlands is rapidly changing. The land of prosperous towns and villages embedded in rich, flat and open agricultural land is turning into a metropolis. A distinctive quality of this metropolis is the mix of highly urbanized centres and open, green areas that come in different shapes and sizes. But how to design an appropriate planning system for this environment? Mixing “red” (urban) and “green” (rural) land uses, for instance, now becomes problematic as Dutch spatial planning has always focused primarily on the urban domain whereas planning of green areas has its origins in agricultural land consolidation policy. A genuinely integrated approach to the planning of built-up areas and green areas in the open spaces is a distant ideal in this setting. In addition, the regional administrative level, being so important for metropolitan spatial challenges, needs reinforcing. The authors make a plea for a reframing of the notion of spatial planning at the national and provincial geographical and administrative scale. It takes a new object for planning, design and analysis to do the trick. The traditional rural–urban opposition is traded for “metropolitan landscape”, a new image reflecting the integration of built-up and non-built-up distinctively urban and rural land uses. Planning for the metropolitan landscape requires a reassignment of duties and responsibilities among national, provincial and municipal governments and other stakeholders.  相似文献
