Characteristics and driving forces of spatiotemporal use change in urban agglomerations from the perspective of functional zoning - Taking the Central Plains urban agglomeration as an example

Abstract

Functional zoning is an effective method to disclose the spatial diversity of land and a prerequisite for the optimization of national land space. We explore the spatial and temporal characteristics of land use in the Central Plains urban agglomeration from 1990-2020，and the GWLR model was used to investigate the key driving elements for the land change in the urban agglomeration as a whole and in different land use function zones. The results indicate that (1) the most significant changes occurred on cultivated and construction land, with land use change intensities of 1.42% and 1.36%, respectively. (2) There are obvious differences in changes among different land function zones: The core economic zone has the highest proportion of change from cultivated land to construction land; in the belly of urban zone and the main agricultural production zone, due to the lack of natural forest and grass growing conditions, the change in land type is also manifested as the extension of construction land. (3) There are large differences among the motivating elements of cultivated land and construction land change in varied eras and different land use function zones, and changes in construction land are more influenced by socio-economic factors.
