Study on the Spatio-temporal Correlation between Multidimensional Urbanization and the Evolution of Rural Territorial Functions:A Case Study of Jianghan Plain
Exploring the complex correlation between urbanization and the evolution of rural territorial functions is not only an important proposition of rural-urban integration and rural revitalization in the new era,but also the frontier of rural geog-raphy research.Taking Jianghan Plain in 2000-2019 as the research case,based on the urbanization index system and ru-ral territorial function evaluation model,this paper explores the temporal correlation regularity and spatial correlation char-acteristics between multidimensional urbanization and rural territorial functions by applying the method of systematic dy-namic panel model,spatio-temporal geographic weighted regression model.The results show that:(1)there are obvious structural differences in the evolution of rural territorial functions in Jianghan Plain,in which the comprehensive function of rural areas had changed in stages in terms of time,and it had evolved from an inverted U-shaped distribution pattern a-long the development axis of Jiaoliu-Changjing to a T-shaped distribution pattern along the Hanyi Line-East Plain Belt in terms of space.(2)Multidimensional urbanization and rural territorial functions in Jianghan Plain showed complex charac-teristics in temporal correlation.On the one hand,the correlation between population,economic urbanization and compre-hensive function of rural areas show an"N"-shaped curve regularity,and the correlation between urbanization and compre-hensive function of rural areas presented a monotonic increasing trend.On the other hand,the elastic coefficient value was lower than the positive effect value of population and economic urbanization in the later period.(3)The spatial correlation between multidimensional urbanization and rural territorial functions in Jianghan Plain shows obvious regularity and hetero-geneity.The research results are helpful to enrich the theoretical connotation of rural geography and provide support for the practice of rural-urban integration and rural revitalization in Jianghan Plain.
