摘要

随着城市人口的增长和城市地区的扩大,城市生态系统提供的一系列服务在未来几十年将变得越来越重要。这些生态系统的恢复和维护对于促进生物多样性保护、人与自然的相互作用以及缓冲气候变化的影响至关重要。因此,我们设计这些城市生态系统,使其能够适应气候变化和城市压力,这一点至关重要。城市生态系统的新颖性及其独特的制约因素和压力源意味着,与传统的自然环境修复相比,城市生态系统需要独特的管理和设计实践。此外,这些新的城市生态系统缺乏可进行比较的类似生态系统,这使得量化恢复成功变得困难。因此,生态恢复力——维持由本地物种主导的富裕社区——成为衡量城市恢复成功与否的更有意义的标准。在此,我们提出了一套旨在促进城市生态弹性的管理策略。具体来说,我们关注物种池选择、遗传输入、景观连通性和管理制度。虽然这些因素在所有生态系统恢复中都很重要,但这些过程在城市生态系统中发挥着巨大的作用,因为它们具有独特的压力,包括入侵压力加剧、原生种子库枯竭、景观破碎化程度高和社会经济限制。通过关注生态系统的恢复能力,城市栖息地的恢复可以降低长期成本,增加生物多样性保护,改善人类健康和福祉。

Best practices for designing resilient urban ecosystems through native species restoration
Urban ecosystems provide a range of services that will become increasingly important in the coming decades as urban populations grow and urban areas intensify. Restoration and maintenance of these ecosystems is vital to the promotion of biodiversity conservation, human-nature interactions, and buffering against the effects of climate change. It is therefore crucial we design these urban ecosystems to be resilient to both climate change and urban stressors. The novelty of urban ecosystems, and their unique constraints and stressors, means that they require unique management and design practices than those used for conventional restorations in natural environments. Additionally, these novel urban ecosystems lack an analogous ecosystem to which comparisons can be made, which makes quantifying restoration success difficult. As such, ecological resilience—the maintenance of rich communities dominated by native species—becomes a more meaningful metric of success for urban restorations. Here, we propose a suite of management strategies designed to promote urban ecological resilience. Specifically, we focus on species pool selection, genetic input, landscape connectivity, and management regimes. While these considerations are important in all ecosystem restorations, these processes play an outsized role in urban ecosystems due to their unique pressures including heightened invasion pressure, depleted native seed pools, high degrees of landscape fragmentation and socio-economic constraints. By focusing on ecosystem resiliency, urban habitat restorations can be maintained with decreased long-term costs, increased biodiversity conservation, and improved human health and well-being.

期刊介绍: Urban Forestry and Urban Greening is a refereed, international journal aimed at presenting high-quality research with urban and peri-urban woody and non-woody vegetation and its use, planning, design, establishment and management as its main topics. Urban Forestry and Urban Greening concentrates on all tree-dominated (as joint together in the urban forest) as well as other green resources in and around urban areas, such as woodlands, public and private urban parks and gardens, urban nature areas, street tree and square plantations, botanical gardens and cemeteries. The journal welcomes basic and applied research papers, as well as review papers and short communications. Contributions should focus on one or more of the following aspects: -Form and functions of urban forests and other vegetation, including aspects of urban ecology. -Policy-making, planning and design related to urban forests and other vegetation. -Selection and establishment of tree resources and other vegetation for urban environments. -Management of urban forests and other vegetation. Original contributions of a high academic standard are invited from a wide range of disciplines and fields, including forestry, biology, horticulture, arboriculture, landscape ecology, pathology, soil science, hydrology, landscape architecture, landscape planning, urban planning and design, economics, sociology, environmental psychology, public health, and education.
