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.

This study aims to reveal the relationship between the social structure and urban pattern in a specified urban area by means of the socio-spatial dialectic. To understand the circumstances behind this dichotomy, analyses were conducted on two intertwined subjects - social structure and morphology - as part of a case study of the historical core of the Kadıköy district in Istanbul, Turkey. Based on the findings, some inferences, depending on the predefined social and morphological components, are made about changing socio-spatialities in the given place by means of time-spacesociety relations. The results show that each socio-cultural group brought their own culture and adapted their physical environment according to their basic needs, and that culture has a restrictive and explanatory effect on the formation of space. In addition, population growth and the adaptive capacity of society to external forces demanding change in the urban space also turn out to unavoidably affect the development scheme of the morphological character of the area.

During the last decade, there has been a rapid increase in the research literature dealing with the measurement of urban sprawl. Density gradients, sprawl indexes, and certain simulation techniques are some of the quantitative measures that have been used in previous studies. Fractal analysis has also been applied in describing urban areas and a fractal theory of cities has been proposed. This study attempts to measure urban sprawl using an index relating density and proximity and relating this to the fractal analysis of urban sprawl using the example of Istanbul, a large city that hitherto has not been measured or characterized using such techniques. Measures of sprawl were calculated at each neighbourhood level and then integrated within an index using 'density' and 'proximity' factors. This identifies the pattern of urban sprawl during six time slices defining five periods from 1975 to 2005. The urban form of Istanbul is then quantified through fractal analysis in the given years in the context of the dynamics of urban growth. Our findings suggest that the fractal dimension of urban form is positively correlated with the urban sprawl index when urban growth is more likely to be 'concentrated'. This is in contrast to a negative relationship which is observed between the fractal dimension and the sprawl index when the urban growth pattern has a more dispersed, semilinear form.

The main objective of the paper is to understand the spatial behavior and structure of coastal cities based on their socioeconomic development levels quantitatively. The geospatial metrics were used to describe the urban growth patterns in cities of İzmir, Kocaeli, Antalya, Tekirdağ, Mersin, Samsun, Çanakkale, Giresun, and Sinop in Turkey. The land-use data was obtained from satellite imagery of 1987s, 2000s, and 2015s. The results indicate that as the socioeconomic level of coastal cities increases, urban patterns become more complex and their centrality decreases. The linear growth along the road increases, while the linear growth along coast is decreasing. While the coastal city in the lower-level development has more dynamic behavior, the one in upper-level development has stabilized effects. The density, as a key policy indicator in urban spatial growth, has impressively contributed to the interpretation of the spatial behaviors. The results are significant for decision-makers to support appropriate strategies for sustainable land use and rethinking land use policies of coastal cities. • Coasts, as well as being a topographic threshold, are an attractive natural element driving urban growth. • The results indicate that the levels of socio-economic development in the coastal cities influence urban spatial growth. • Geospatial measurements provide a robust characterization of urban morphological structures and are useful for representing urbanization processes.
