This study aims to evaluate the impact of urban spatial expansion on the landscape patterns of coastal cities in Türkiye through the use of spatio-temporal indices. To this end, temporal samples covering a period of approximately 30 years (1986-2000 and 2000-2015) were analyzed for six selected coastal cities in Türkiye. The urban spatial growth patterns in these cities were characterized using 17 geospatial indices, and Pearson's correlation coefficient and principal component analysis were employed to assess the quantitative relationships between urban spatial development and the fragmentation of landscape networks. The results of the study demonstrated that the patterns of landscape fragmentation caused by the spatial growth patterns of the selected coastal cities can be divided into two categories: disconnected landscape connections and perforated landscape patterns. Leapfrog development was identified as a major factor in the fragmentation of landscape continuity, leading to the formation of perforated green structures. The findings of this research can serve as spatial guidelines for addressing disconnected landscapes, a crucial factor in enhancing urban sustainability in Türkiye's coastal cities. Furthermore, the outcomes of this study may be useful for informing the national well-being strategy for urban planning and natural mitigating policies in Türkiye's coastal regions.
本研究旨在通过时空指数评估城市空间扩张对土耳其沿海城市景观格局的影响。为此，对土耳其六个选定的沿海城市进行了约 30 年（1986-2000 年和 2000-2015 年）的时间样本分析。使用 17 个地理空间指数来描述这些城市的城市空间增长模式，并采用 Pearson 相关系数和主成分分析来评估城市空间发展与景观网络破碎化之间的定量关系。研究结果表明，所选沿海城市空间增长模式导致的景观破碎化模式可分为两类：不连续的景观连接和穿孔的景观模式。跨越式发展被确定为景观连续性破碎化的主要因素，导致穿孔的绿色结构形成。本研究的结果可以作为解决不连续景观的空间指南，这是提高土耳其沿海城市城市可持续性的关键因素。此外，本研究的结果可能有助于为土耳其沿海地区的城市规划和自然缓解政策的国家福祉战略提供信息。
