Abstract:
The topic of this thesis is the evaluation of the ecological sustainability of urban green spaces. The focus is on the significant influence of maintenance on ecological sustainability and the extent to which the size of an urban green space plays a role in ecological sustainability. As part of this study, a representative survey of experts from the field of landscape architecture and horticulture was carried out. A concept was then developed to determine the extent to which urban green spaces can be assessed in terms of ecological sustainability. By analysing and interpreting the results, it can be shown that maintenance has a significant influence on ecological sustainability. The utilisation requirements of the various green spaces must be taken into account for targeted maintenance management. The focus here is on water utilisation, plant use and the preservation of biodiversity. It has also been shown that urban green spaces of around half a hectare in size can have the greatest impact with a well-planned selection of plants that help to improve air quality and reduce temperatures. In future, ecological sustainability must play a decisive role right from the planning stage and landscape architects and garden landscapers must regularly exchange information on plant selection for appropriate maintenance.
