Therefore, many domestic and international scholars have conducted in-depth research on the optimal allocation of URs as an important issue for sustainable urban development. In this situation, it was realized that demolition and reconstruction of building ruins is neither an economically viable nor environmentally friendly solution on a large scale, so it is necessary to address this situation by renovating and retrofitting the existing URs. The biggest practical problem facing cities is that the current carrying capacity of first-tier cities is gradually becoming saturated, especially the shortcomings of housing, education, and medical care are more obvious, and public facilities are facing great pressure.
It states that construction waste accounts for one quarter of the total urban waste in Guangzhou and that environmental pollution and ecological damage must be prevented at the root. The environmental impact report of the Guangzhou Construction Waste Disposal Facilities Layout Plan (2021–2035), was published in Guangzhou in 2021.
Some relevant policies are mainly China’s national environmental strategy of carbon peaking and carbon neutralization proposed in 2020, which aims to address global climate change, promote the implementation of improvements in critical regions and enterprises, and support the overall reform and sustainable development of economic production and life. As a result, numerous industrial buildings have been left in the city center, where land prices are rising, and they are becoming URs. On the other hand, due to the influence of multiple factors, such as the structural adjustment of industrial land for industrial upgrading and the decline of the performance of the building itself, the heavy industrial parks in the city center are either closed or relocated to the urban fringe. The number of bankrupt real estate enterprises in Guangdong Province ranked first for three consecutive years, accounting for approximately one fifth of all bankrupt real estate enterprises. After counting, it was found that approximately 343 real estate companies in China issued relevant bankruptcy instruments in 2021. They searched the People’s Court Bulletin website with “real estate” as the keyword and eliminated duplicates and non-real estate companies from the list. Figure 1 is the official data released by the official website of the China Real Estate Association. However, since 2020, influenced by COVID -19, the residents’ enthusiasm for buying a house has obviously weakened. The proportion of China’s urban population has soared from 35.39% in 2000 to 64.72% in 2021, which has brought a huge demand for housing land and infrastructure investment, the real estate industry has risen rapidly under this situation. On the one hand, the rapid expansion of urban space. There are many reasons for the formation of URs. Finally, a complete research system is established to implement URs’ projects, which provides a clearer systematic planning strategy for the reuse of URs in the future. Specifically in the present study, the ten representative URs in Guangzhou are first evaluated by the Analytic Hierarchy Process and then combined with AI methods, such as the adversarial generative networks and big data applications, into the reuse design of URs.
With the development of artificial intelligence, technologies such as Generative Adversarial Network (GAN), Easy DL, and Natural Language Processing (NLP) can provide technical support for urban ruin reconstruction, from design to operation. However, the current renovation of URs is based on fragmented renovation strategies for different URs without a systematic and universally applicable renovation methodology. Generally, methods such as demolition and reconstruction of original buildings or upgrading and transformation are used to reuse URs, and some of them have achieved fruitful results. At present, the types of urban ruins mainly include industrial ruins, abandoned urban buildings, and war sites. This significantly affects the happiness of residents around the URs, the overall image of the city, and the environment, and it has become an important issue in urban construction. In recent years, with the continuous deepening of the urbanization process, the problem of urban ruins (URs) has become prominent.
