摘要：Across Europe, Greenways upcycle disused railway infrastructure into
non-motorised public infrastructure, often with limited consideration
to potential ecological synergies. Pre-development, disused transport
corridors become relatively undisturbed and potentially host diverse
semi-natural habitats. The study objectives were 1) to produce a highly
detailed and accurate dataset using remote sensing with rapid assessment
techniques for ground truthing and 2) subsequently examine habitat
diversity existing along a proposed Greenway. A 7000 ha study corridor
was based on a disused railway proposed as a transfrontier Greenway
connecting the Republic of Ireland and the United Kingdom. The study
applied a rapid-assessment virtual validation techniquealongside remote
sensing and accuracy assessment. Inter-relationship between seminatural
habitat diversity and land-use intensification was examined.
Remote sensing accuracies of 89% and 99% for a real and linear habitat
classification were obtained. Degrees of land-use intensification
were observed throughout the corridor, highlighting the importance
of maintaining and enhancing remaining semi-natural habitat that
exists along the proposed Greenway route. Through understanding
the landscape matrix composition and semi-natural habitat diversity,
European Greenwayscan achieve multi-functionality for ecosystem
conservation, forming integral components of Green Infrastructure.
