摘要

Land use change has had a crucial impact on ecological and socioeconomic systems. This study takes the main urban area of Zhengzhou as an example and constructs a comprehensive analysis framework based on the “transfer-conversion-change” centroid model, which precisely illustrates the trends of urban land use change from 2010 to 2020. The results indicate that: I. From 2010 to 2020, the area of building land, forest land, and grassland continuously increased, while cultivated land decreased significantly. II. Spatial migration characteristics showed southwestward centroid shifts in building land, forest land, cultivated land, unused land, and water bodies. III. Dynamic conversion processes revealed divergent trajectories: forest land conversion drove northeastward centroid migration, while transitions of building land and grassland predominantly shifted southward, contrasting with the northward movement observed in cultivated land, unused land, and water body conversions. IV. Post-change aggregation patterns exhibited regional clustering, with grassland, cultivated land, and unused land centroids shifting northwest, forest and water areas moving southwest, and building land migrating northeast. This study established an integrated analytical framework through the centroid model, expanding its application in land use change analysis and addressing theoretical gaps in quantifying interactions between land use types.
