Urban Renewal Potential of Old Urban Areas in Resource-Based Cities in Developing Countries: A Case Study of Dongsheng District, Ordos, China

Many developing countries have experienced or are experiencing periods of rapid urbanization, and the sustainable development of resource-based cities has increasingly come under the spotlight. The extensive mining of resources, which once propelled the economic growth of these cities, has enabled the continuous construction of more urban districts. However, as these new districts become favored, the old districts in these cities tend to be overlooked. This neglect becomes particularly pronounced once the resources start to dwindle, with older districts, which lack contemporary facilities, declining over time. Dongsheng District, in China's Ordos City, is a prime example of this phenomenon. In this study, we took Dongsheng District as the research subject to explore the urban renewal potential of old urban areas in resource-based cities in developing countries. First, we constructed an assessment system for evaluating the urban renewal potential of old urban areas in resource-based cities in developing countries. Using ArcGIS, we conducted a quantitative evaluation of the spatial distribution of urban renewal potential indicators in the assessment system. Second, we conducted a comparative analysis by juxtaposing the spatial distribution of urban renewal potential derived from the assessment system with the current land use and historical development of the study area to explore potential correlations. Third, we propose the distribution of urban renewal potential in old urban areas of resource-based cities in developing countries by discussing the research results. The research found that in relation to current land use, residential and commercial service areas are more likely to form high-potential plots. Urban villages are often considered to have high potential for urban renewal, but in these urban areas, they do not always exhibit significant urban renewal potential. Regarding the relationship with historical development, urban renewal potential generally shows a negative correlation with historical development, and most other specific indicators of urban renewal also show a correlation with historical development.
