Geosystem–Ecosystem Interactions and Land Use Dynamics in Western Tehran: A Fuzzy Logic–Based Geospatial Assessment

The accelerated urban growth of Tehran has introduced significant modifications to its underlying geosystems, with cascading effects on ecological patterns and land use dynamics. This research investigated the dynamic relationship between Tehran’s geological evolution and its ecological conditions, focusing on how geosystems influenced the ecological dynamics of western Tehran, particularly regarding land use patterns. The novelty of this work lies in integrating geosystem variables (lithology [L], river proximity [R], and fault distribution [F]) into a fuzzy logic–based a land use (LU) change index, empirically validated through a network of control points. The research was conducted in the foothills of the Alborz Mountains and along the Vardij River. Data collection involved geological mapping, remote sensing, and field studies. The findings emphasized the critical role of geosystems in shaping ecosystems, revealing that significant land use changes occurred within a susceptible LU index range of ۴.۰۲ to ۴.۹۰, contrary to the belief that high LU indexes predominantly drive urban development. This transformation was influenced by the rugged topography and the optimization and vulnerability of the studied variables, highlighting the need for effective environmental management and conservation strategies in the face of increasing urbanization pressures. Ultimately, this study underscored that understanding the relationships between geosystems and ecosystems was essential for preserving the ecological integrity of western Tehran. By integrating geological factors into land use planning, stakeholders could better manage natural resources and protect the region's ecological heritage.
