摘要：	A dynamic combination of environmental, social, and economic factors shapes and manages the urban landscape. Understanding these factors behind urban growth can help us discern more about its past and future. This study examines the fractal dimension of the built-up area (BUA) boundaries of two municipalities in the emerging South Bengal Region (SBR) urban areas that have developed gradually over the last three decades. Fractalyse software (version 3.0-0.9.1) was used to estimate the fractal dimension using the box-counting method and generalized nonlinear and logarithmic models to link the changing socioeconomic patterns of the study areas over time. The fractal dimension measurement increased significantly between 1991 and 2021, with the overall global structure growing similarly to large metropolises in developed economies in the 20th century. In particular, the models have offered a framework for examining the link between urban form and socioeconomic structure to construct the concept of spatial replacement dynamics in urban landscapes. The results of this study have the potential to aid cities in gaining a deeper understanding of the possibilities and threats they will face in the future and in formulating efficient plans to improve their adaptation and resilience. The findings of this study also imply that urban fringes are conducive to denser expansion and prosperous economic growth. The fractal dimension values decrease as the distance from Kolkata, the core city, increases, while upscaled industrial zones create inhospitable landscapes along the Hooghly River. Therefore, this study suggests several recommendations for sustainable growth and development corresponding to the rapid urbanization of eco-sensitive zones in developing economies. According to this study, the SBR's population is anticipated to expand, suggesting that economic forces would contribute to the region's urbanization, tending toward built environment saturation. While population growth and development are desirable, they may pose social, economic, and environmental challenges in the studied regions if they occur at an insufficient pace.
