Spatial Heterogeneity of Sustainable Land Use in the Guangdong–Hong Kong–Macao Greater Bay Area in the Context of the Carbon Cycle: GIS-Based Big Data Analysis

Abstract

The primary object of this study is to survey the spatial heterogeneity of sustainable land use in the Guangdong–Hong Kong–Macao Greater Bay Area, The introduction of GIS technology into the evaluation index system under the traditional concept of circular economy, combined with the “double carbon target” and the methods of entropy weight analysis and superposition analysis led to the establishment of the evaluation index system for sustainable land use in the GIS model. The evaluation’s findings indicate that: (1) Spatially, the horizontal gravity center of sustainable land use in the Guangdong–Hong Kong–Macao Greater Bay Area changed dimensionally from 2010 to 2021, and the spatial gravity center shifted from north to south. (2) In terms of time characteristics, sustainable land use showed a steady upward trend in the 11 years from 2010 to 2021. (3) There were regional differences and uneven development levels in the comprehensive evaluation of sustainable land use in the Guangdong–Hong Kong–Macao Greater Bay Area. It shows that there are great differences in the degree of social and economic development among federation-level cities in the Guangdong–Hong Kong–Macao Greater Bay Area. From the current research on the sustainable use of land resources, the evaluation of sustainable use of land based on the concept of a circular economy is less favorable. Thus far, there has been no case study on land sustainability in the Guangdong–Hong Kong–Macao Greater Bay Area based on carbon cycles. In this study, the results are systematically sorted out, and the influencing factors are analyzed in depth to provide theoretical guidance on the sustainable and circular development of society, culture, and economy in the Guangdong–Hong Kong–Macao Greater Bay Area.

Towards Sustainable Rural Revitalization: A Multidimensional Evaluation of Rural Vitality in China's Traditional Villages

“…Employing the raster calculator tool of ArcGIS 10.8 and applying the weighted superposition method, this study conducts a comprehensive analysis of each evaluation index. The calculation method is as follows [65]:…”

“…Here, Wi signifies the weight of the ith index, and Yi denotes the standardized value of the ith index [65]. A higher RVA value corresponds to a heightened level of vitality, while the reverse holds true.…”

Research on the Spatiotemporal Evolution and Driving Mechanism of Coupling Coordinating Between Green Transition of Urban Land Use and Urban Land Use Efficiency: A Case Study of the Yangtze River Delta Region in China

“…The spatial heterogeneity of land resources refers to the complexity and variability of socio-economic and ecological attributes of land systems or system properties in space, generally divided into structural heterogeneity and functional heterogeneity. In essence, it re ects the complete manifestation of the natural and economic attributes heterogeneity of land resources, which can be expressed speci cally as heterogeneity in quantity, quality, location, space, structure, composition, and other attributes of land resources (Chen et al 2023, Zhang et al 2016. Speci cally, due to the differences in inherent resource endowments of YRDR, there are regional disparities in economic development, which directly impact the quantity, morphology, and spatial layout of urban land.…”
