The process of urban sprawl, restructure, and shrinkage provides the possibility for the formation and evolution of urban wildscapes. Physically, urban wildscapes refer to the urban spaces where the ecology is basically dominated by natural processes and similar to the natural wilderness in appearance and functions. The existence and persistence of wilderness fragments in cities often result from the reduction of human management and with minimal intervention on the nature. Due to the different interactions and confrontations between natural processes and social processes, the wildness of urban wildscapes varies. The unique and irreplaceable values of urban widlscapes in ecology, culture, aesthetics, economy, and well-being have gained multi-disciplinary attention and been widely recognized. This paper defines the concept of urban wildscapes, reviews the conceptual development of its connotation, and analyzes the multiple benefits of urban wildscapes on the basis of value recognition research. It hopes to provide a value recognition framework for empirical studies, helping urban residents, planning designers, and managers identify, appreciate, experience, and sustainably manage natural resources and urban ecological network, and providing scientific guidelines for ecological urban development.  相似文献

Wilderness is a cultural construct that is deeply rooted in many societies. For landscape architects and their predecessors, wilderness has long been important as a contrast to artificial garden elements, as an inspiration for naturalistic plant designs, or today as a timely contribution to reconciling cities and their inhabitants with the natural world. Since cities and wilderness have traditionally been seen as opposites, new approaches are necessary to better address the opportunities and challenges associated with wilderness in urban regions. From an ecological perspective, urban wilderness can be defined as an area characterized by a high degree of self-regulation in ecosystem processes where direct human impact is negligible. This allows two main types of wilderness to be distinguished: “ancient wilderness” represented by natural remnants in many cities, and “novel wilderness,” which arises in artificial urban-industrial sites. The two types require different approaches in designing and managing green spaces. Ancient wilderness is a traditional object of conservation and restoration, and offers inspiration for naturalistic plantings. In contrast, the emergence of novel wilderness has long been associated with neglect and socio-economic decline. Since the 1980s, however, early pioneer projects in Germany have started to integrate novel urban wilderness into the green infrastructure. The results are unprecedented green spaces that combine novel wilderness with design interventions. These places are attractive to visitors, contribute to biodiversity conservation, and support many ecosystem services. This article aims to illustrate the opportunities and challenges of integrating wilderness components and processes into the urban green infrastructure—a timely way to reconnect cities with nature.  相似文献

Fragments of wilderness dominated by natural succession exist in urban environments, and play a critical role in protecting biodiversity, supporting urban ecological processes, and connecting human beings with nature. Urban vegetation rewilding is a key approach to restricting urban wilderness by restoring the species composition, community structure and functions, eventually towards a self-maintained vegetation community. This paper, taking wildflower meadows as a reference, establishes a technical framework of urban vegetation rewilding by leveraging ecological flows and adopting quasi-nature design with minimum interventions. The framework covers 5 aspects, namely self-design, micro-topographic design, quasinature design, collaborative symbiosis design between plant community and keystone animal species, and design with natural materials. Studying the green space along the northwest lakeside of the Shuangguihu National Wetland Park in Liangping District, Chongqing, this paper provides a scientific guidance and technical paradigm for vegetation rewilding and urban wilderness restoration in the complex context of natural–artificial urban landscapes.  相似文献

One of the core values of urban wilderness construction is to restore the structures and functions of biological communities in fragmented urban habitats, and enable the stability and ecological succession of native communities with low human intervention. The paper discusses the design principles and technical methodologies in active urban rewilding by the example of Shanghai Urban Biodiversity Education Base project. Aiming to restore urban biodiversity and enrich the technical and theoretical research of urban wilderness construction and Nature-based Solutions, this project conducted habitat division, native species introduction, natural community construction, ecological benefit assessment, etc. In a year and a half, 260 native plant species, 255 insect species, 7 amphibian and reptile species, 71 bird species, and 6 mammal species were recorded within the 1.7 hm2 project site, showing higher biodiversity and density of animal populations than unrestored consructed forests surrounding. Along with the spontaneous progressive succession of the plant communities, the project has achieved good results. The technical approaches proposed in the project can be broadly applied in design and construction of country parks, wildlife habitats, ecological corridors / networks, and environmental education bases.  相似文献

对规划地段的自然生态状况深入而全面研究的普遍缺乏是当前城市规划工作的共同特点和缺点。作者提出面对人口的剧增、环境的恶化、物种的丧失等一系列生态矛盾与困惑,需要把规划方案建立在坚实的生态调查研究的基础上,使建设与地方的自然状况协调适应,符合区域固有的生态环境与运行规律。生态评价是达成这一目的的一条途径。  相似文献

城市生态问题的实质,是人与环境关系的失范,是环境伦理学范畴。城市生态规划是在大尺度上处理城市发展与生态环境保护关系的实践科学,需结合环境伦理学的最新理论与方法进行原则思辨。在具体的规划设计方法上应尊重自然,正确设定城市发展的限度与阈值,在城市自然生态可承受范围内,采取与环境更加包容的发展策略。要按照自然优先、代际公平、互利合作的原则重建城市近自然。按照生态承载力要求为城市的发展设定上限,在满足城市发展的同时取得环境健康的统一,同时转变增长方式,取得人与自然的协同发展。这样就能够从工业文明走向生态文明,建设更加可持续、健康的城市。  相似文献

In this text we take a closer look at the development of the wilderness metaphor of the Zwischenstadt, that is, fragmented urban landscapes in Germany. We trace the metaphor's meanings back to its origins in the conservative cultural criticism of Wilhelm Heinrich Riehl of the mid-nineteenth century and analyse the different meanings of ‘wilderness’ in today's urban and landscape planners’ positions. Our aim is to demonstrate that the meanings of the concept of wilderness, as well as those of city and cultural landscape, differ depending on the context in which they appear. We point out that different values can be attached to each individual meaning. These evaluations depend on cultural and political patterns and on one's own world view. We apply the insights thus gained to identify three different types of design strategy for the Zwischenstadt used by urban and landscape designers.  相似文献

基于水土生态理论研究视野下的城市水土保持   总被引:3,自引:0,他引:3  
在当今社会迅猛发展的城市化热潮下,自然生态环境受到了巨大的冲击,城市正面临着水土流失问题的侵扰。文章着重论述了城市化对自然生态产生的不同影响以及水土流失对城市的危害,并以其他国家的城市水土治理手段为范例,对深圳湾及总体环境进行了合理的数据分析,认为水土流失有显性水土流失和隐性水土流失,而保持水土生态平衡是城市水土保持的基本要求。基于水土生态理论的城市水土保持归根结底地还是要解决好人与水的关系、人与土的关系、人与植被的关系并依此创造丰富多彩的水土生态文化,积累更多保护、适应和合理利用水土生态资源的传统、方式和经验,是人与自然和谐的基本保证,也是城市水土保持所要实现的目标。  相似文献
