| Summary: | The expansion of construction land is a key feature of urbanization. Understanding its spatiotemporal evolution in Yunnan’s plateau basins is crucial for minimizing resource waste and promoting coordinated regional development. This study employs land use and nighttime light data to analyze the spatiotemporal dynamics of construction land expansion and its decoupling from economic growth, using various indices and the Tapio decoupling model. The results reveal a steady rise in urban construction land from 1990 to 2020, characterized by significant spatial variations in expansion speed and intensity. Edge expansion predominated throughout all periods, accounting for over 50% in most regions. After 2010, expansion spread into smaller basins, markedly increasing the number of areas experiencing new expansion. The decoupling between construction land expansion and economic growth in these basins remains primarily weak and unstable, indicating a strong reliance on land for economic development. Factors such as socioeconomic conditions, geography, ecology, and policy influence both land expansion and economic growth, highlighting the interdependence between the two. These findings provide a foundation for sustainable basin development and offer valuable insights for planning and policy-making. |
