Description

This study investigates the spatio-temporal differentiation and coupling coordination characteristics of the "PLES" – production space, living space, and ecological space – in the middle and upper reaches of the Yellow River region. The objective is to explore the spatio-temporal evolution patterns and interrelationships among these spaces. Given the ongoing promotion of ecological civilization and high-quality development by the state, counties, as crucial entities for ensuring food security and promoting regional sustainable development, must scientifically and rationally coordinate ecological, agricultural, and urban functional spaces. Based on the unique geographical and human characteristics of the middle and upper reaches of the Yellow River, this study examines the layout features, transfer rules, and collaborative development models of the county-level "PLES" in this region. Utilizing data synthesis methods, spatial analysis, and quantitative modeling, we analyzed land use data from 1980 to 2020 in the middle and upper reaches of the Yellow River. We identified and quantified the spatio-temporal evolution characteristics of the "PLES" in this region's counties. Additionally, using the GIS platform and remote sensing datasets (CNLUCC), we conducted spatial reclassification and established a transfer matrix and modified coupling coordination model to calculate and analyze the spatio-temporal variation trends and coupling coordination degrees across different periods. Through comprehensive analysis, this paper reveals the characteristics of coordinated development within the county-level "PLES," providing a critical theoretical and practical foundation for the harmonious development of regional ecological protection and socio-economic activities, thereby supporting the efficient utilization and sustainable development of regional territorial space.
