Spatial Correlation Evolution and Driving Mechanism of County Land Use Function Network Under the Background of Urban-Rural Integration:A Case Study of Han River Basin in Hubei Province
Multifunctionality of land use is not only an important means to alleviate the conflict between human activities and land,but also a crucial factor in achieving sustainable development.This study focused on the Han River Basin as the research area and aimed to define the interaction mechanism between land use functional networksand urban-rural integration.By employing comprehensive methods such as land use multifunctional evaluation,social network analysis,and spatial metrology modeling,a multifunctional land use network was constructed under the context of urban-rural integration.The evolution characteristics and driving mechanisms of this network were further explored.The findings indicated that:(1)with an increasing rural-urban integration,there existed an increase in node centrality,network density,and network reciprocity of both production function networks and living function networks in rural-urban areas.The spatial distribution followed a pattern of downstream>midstream>upstream.However,for ecological function networks,although node centrality decreased slightly with an increased integration level,there was little change in network density or reciprocity,showing a distribution patter of upstream>midstream>downstream.(2)Among the driving factors affecting production function networks,both rural-urban integration degree and its spatial lag term significantly inhibited node centrality,but positively promoted network density and reciprocity.(3)The analysis of living function network showed that the degree of urban-rural integration had a positive effect on the living function node centrality,network density and network reciprocity.(4)For ecological function networks,rural-urban integration did not have significant effects on node centrality,but had a significant positive impact on both network density and reciprocity.The results of this study are of great practical significance for realizing urban-rural integration and promoting regional sustainable development.
