Evaluation of production-living-ecological space conflicts and driving force analysis in the Dawen river basin under rapid urbanization

Identifying the evolution laws and driving mechanisms of the conflicts among production, living and ecological spaces during the rapid urbanization process in the DaWen River Basin is of great significance for promoting the optimization of territorial space and sustainable development within the basin. Based on land use data, the transfer matrix, spatial conflict index model and geographical weighted regression model were used to systematically analyze the evolution of the three types of spaces, the evolution of spatial conflicts and the driving factors. The results show that from 1990 to 2020, the changes in the three types of spaces in the basin were mainly characterized by the reduction of agricultural production space and the expansion of industrial production and urban living spaces, with the core of spatial transfer being the transfer of agricultural space to living and industrial spaces; the spatial conflicts among the three types of spaces changed from high to medium conflicts; in the study of the driving mechanism of conflicts, the topographic relief was the primary factor affecting the conflicts among the three types of spaces, with natural factors showing a negative correlation and social economic and accessibility factors showing a positive driving effect. The research results can provide theoretical support for the optimization of territorial space and the formulation of ecological protection policies in the basin.
