Abstract

The high urbanization rate of Istanbul in response to rapid population decreased the size and amount of green spaces. Thereby, every green space types are of vital importance in terms of conservation of urban biodiversity. In this study, it was aimed to compare woody species composition of main green space types consist of artificial and natural sites. Botanical gardens had the highest diversity followed by gardens. Residential areas showed to be important in terms of shrub (52%) and evergreen species (58%), which are mostly exotics (71%). The ratio of the invasive plants in the composition was higher in parks, which contain highway greenings and public gardens. Since the most tree species used in public green areas of Istanbul were mostly same with the species used in European cities, all of the green space categories having varied composition must be considered as interconnected habitat patches in urban planning.

摘要

伊斯坦布尔的快速城市化率是人口快速增长的结果，绿化面积和数量减少了。因此，就保护城市生物多样性而言，每种绿色空间类型都至关重要。在这项研究中，旨在比较由人工和自然场所组成的主要绿地类型的木本物种组成。植物园的多样性最高，其次是花园。在灌木（52％）和常绿树种（58％）方面，居民区显示出重要地位，其中大部分是外来物种（71％）。在包含高速公路绿化和公共花园的公园中，入侵植物在组合物中的比例更高。由于伊斯坦布尔公共绿地中使用最多的树种与欧洲城市使用的树种基本相同，
