摘要

The onset of global urbanization has led to a population shift from rural to urban areas and the expansion of urban development [1-3].Urban land areas are growing at faster rates than their populations in most parts of the world [4].The urban sprawl process refers to dispersed land development characterized by low-density,unplanned,and uneven patterns of growth during urban expansion.This process can result in inefficient use of land resources contradictory to the principle of sustainable development [5].Additionally,urban sprawl has various environmental,economic,and social consequences,including the following:loss of agricultural land,higher costs for transportation infrastructure,increased landscape fragmentation,degeneration of soil ecological functions,and reduced ecosystem resilience.It is crucial to understand the trends and patterns of urban sprawl to implement a framework for sustainable urban development in developing regions.
