RETRACTED: Evaluating the Carrying Capacity and Spatial Pattern Matching of Urban and Rural Construction Land in a Representative City of Middle China

Abstract

Evaluation of the carrying capacity and spatial pattern matching of urban–rural construction land is critical for solving problems associated with irrational land use and the destruction of ecosystems. Here, we present a case study exploring the spatial matching relationship between the carrying capacity and current development status of urban–rural construction land in Nanchang, the capital city of Jiangxi Province, China. Land suitability evaluation for urban and rural construction was performed using the analytic hierarchical process and restrictive coefficient method. The spatial matching degree between current construction land and available construction land was obtained by a spatial overlay analysis. Results show that the area most suitable for construction land development (19.2% of the total) is mainly concentrated in the central urban districts, while the relatively suitable area (17.5% of the total) is present around the most suitable area. The ultimate development intensity (i.e., carrying capacity threshold) of construction land in the study region is 41.4%, and the residual development intensity (i.e., development potential) is 24.2%. The available construction land (including most suitable and relatively suitable areas) is generally abundant. The spatial matching degree of construction land ranges from 69.5% to 99.1% in different counties (districts). Pearson’s correlation analysis reveals that the spatial matching degree is positively correlated with the carrying capacity threshold of construction land (r = 0.926; p < 0.01) and the abundance of available construction land (r = 0.732; p < 0.05). The results could be useful for the rational development of urban–rural construction land and the optimization of land space at the city scale.

The Transmission Effect and Influencing Factors of Land Pressure in the Yangtze River Delta Region from 1995–2020

“…The connection between external development, urban-rural income ratio, social consumption and land pressure is primarily favorable, although the number of cities with negative relationships is steadily growing. The expansion of the urban development intensity along with the rapid regional economic growth has led to a continual shift in the direction of intensification in the use of urban land resources, which is beneficial for reducing land pressure [69]. The cities in the Anhui Province should fairly adjust their land use structures since this will increase their capacity for regional sustainable development and decrease land pressure.…”

Spatial Optimization with Morphological Spatial Pattern Analysis for Green Space Conservation Planning

“…In practical applications, these tasks are mainly accomplished through a combined use of ecological importance assessment, spatial analysis, and geographical mapping techniques [18][19][20][21]. Although such methodological framework has been commonly adopted by land use planners, spatial pattern is easily neglected during the planning procedures [22][23][24]. In fact, it is very difficult to find out the optimal spatial pattern of conservation areas simply based on manual methods.…”
