Abstract: Vast rural populations squeezed into cities, leaving small townships hollowed out. Even so, some townships’ lands are still expanding. The dilemma of land expansion with a shrinking population raises various challenges including farmland reduction. Much of the current research on the impervious expansion has focused on urban areas, while townships were often neglected. Based on high-resolution satellite data and statistic data in 1993–2018, this study explored long-term township impervious land expansion dynamics and explored the real-world relationship with their population for the 17 first-batch-of-strong-tourism counties in China. The results showed that over the past 26 years, there had been an increasing trend in the impervious areas in 17 counties. There were diseconomies of scale for impervious land expansion, i.e., the township’s land expansion became less efficient with the shrinking population. The impervious area was predominantly converted from cropland (ranging from 16.40% to 71.96%). The expansion in highlands was also increasing, although most of the growth occurred in the lowlands. The expansion patterns were mainly dominated by infilling and edge-expansion during the early stage, after which leapfrogging occurred, and infilling increased again in recent years. Townships with a “closer” accessibility to tourist attractions had the largest and fastest rate of impervious land expansion and an increasing influence of townships. These counties needed customized development with its unique natural conditions. This study could provide data-based evidence for better planning and governing to promote sustainable development worldwide.
