Spatial Identification and Redevelopment Evaluation of Brownfields in the Perspective of Urban Complex Ecosystems: A Case of Wuhu City, China

Abstract

Rapid industrialization and urbanization in China have led to a rapid increase in the number of brownfields, however there is a lack of identification of the spatial extent of brownfields in cities and accurate assessment of brownfield redevelopment. Based on the relationship between brownfields and urban complex ecosystems, this paper defines brownfields in China and constructs a comprehensive evaluation index system including socio-economic and ecological subsystems. Using Wuhu City as empirical evidence, 19 brownfields were identified using remote sensing data and field surveys. Based on the detection of soil contaminants in brownfields, a fuzzy integrated evaluation method was used to suggest their redevelopment direction. It is found that the government’s planned land use types and the brownfield redevelopment evaluation results match to a large extent, but social, economic and ecological environmental factors should be more fully considered. At the same time, the identification and redevelopment of brownfield sites in the city as a whole need to be carried out by the government’s professional forces in order to obtain more effective and scientific conclusions.

Research into Satisfaction with Industrial Heritage Renewal Based on the SEM-IPA Model: A Case Study of the Dongguan Jianyuzhou Park

“…The core concept of green building revolves around economic, social, and environmental requirements [45,46]. Old industrial buildings are characterized by open space and reliable structures to meet new functional requirements and economic development concepts while maximizing the use of resources, reducing pollution and saving energy [47]. The renewal of old industrial buildings belongs to the project of resource recycling [48], which fully reflects the concept of environmentally friendly buildings [49].…”

Brownfield land redevelopment strategies in urban areas

“…Brownfield developments have social impacts on residents, communities, and businesses and are essential for the viability of any project. Human activities dominate the process of brownfield creation and development (Wang et al, 2022). The property developers highly favoured the two brownfield sites in this study, located in close proximity to local town centres, good schools, rail networks, and other public transport facilities.…”

“…Although he initially accepted the lower return, he later realised that meeting the threshold was the best option for maximising returns for the time and money he had invested in the project. Investment benefits and returns are of primary concern to developers (Wang et al, 2022). As a result of the COVID-19 pandemic lockdowns, the delays led to increased materials costs, labour shortages, and higher interest rates from funders and negatively impacted the financial aspects, as well as creating greater risk for the developer.…”

Large-Scale Automatic Identification of Industrial Vacant Land

“…Similar methods were used in case studies in Guangzhou [22], Changchun [23], and Atibaia [24]. Wang et al [25] used remote-sensing (RS) imagery combined with field research and questionnaires to identify UVL in Wuhu. Song et al [26] combined manual field surveys with open-source data (e.g., maps, Baidu heat maps, business data, and Baidu open street maps) to quantify the UVL of the Changchun City center.…”
