European Greenway developments typically 'upcycle' disused transport corridors for multi-use, non-motorised public infrastructure. The linear and relatively undisturbed nature of these disused infrastructures means many currently function as high quality ecological corridors. Corridors providing connectivity among habitat patches can mitigate the effects of fragmentation on biodiversity, allowing species dispersal throughout the landscape matrix. The sustainable integration of Greenway infrastructure and ecological corridor functions requires consideration during design, development and maintenance stages, taking into account surrounding landscape composition and connectivity. This paper presents a method to characterise a proposed Greenway corridor landscape, focusing on habitat composition and ecosystems connectivity. Morphological Spatial Pattern Analysis (MSPA) was used to comprehensively describe the structural connectivity of linear and spatial habitats occurring within the study area. A subsequent multivariate classification of structural connectivity and habitat data determined six distinctive landscape characters. Interpretation of these landscape characters highlights the principal habitat compositions and connectivity conditions in terms of habitat core, links and potential linkages. For example one landscape was intensified, yet retained high woodland connectivity, while another diverse habitat landscape supported little connectivity for woodland and grasslands. The results of this study suggest significant opportunities exist to enhance European landscape connectivity through informed Greenway development. Crucial habitat linkages can be optimised along Greenway infrastructure, contributing towards the realisation of European Greenways as Green Infrastructure and true sustainable projects.
欧洲绿道的发展通常将废弃的交通走廊“升级改造”为多用途、非机动化的公共基础设施。这些废弃基础设施的线性和相对未受干扰的特性意味着许多基础设施目前作为高质量的生态走廊发挥作用。为栖息地斑块提供连通性的走廊可以减轻破碎化对生物多样性的影响,使物种在景观基质中扩散。在设计、开发和维护阶段,需要考虑将绿道基础设施和生态走廊功能进行可持续整合,同时考虑周围景观的组成和连通性。本文提出了一种用于描述拟议绿道走廊景观的方法,重点关注栖息地组成和生态系统连通性。形态空间格局分析(MSPA)用于全面描述研究区域内线性和空间栖息地的结构连通性。随后对结构连通性和栖息地数据进行多元分类,确定了六个独特的景观特征。这些景观特征的解释突出了主要的栖息地组成和连通性条件,包括栖息地核心、连接和潜在连接。例如,一个景观虽然得到了强化,但仍然保持着较高的林地连通性,而另一个多样化的栖息地景观对林地和草原的连通性支持很少。本研究的结果表明,通过明智的绿道开发,欧洲景观连通性有很大的提升空间。可以沿着绿道基础设施优化关键的栖息地连接,为欧洲绿道成为绿色基础设施和真正可持续的项目做出贡献。
