摘要
With the global urban renewal movement, the phenomenon of green gentrification accompanying the transition of brownfield and idle land to urban green infrastructure has become a hot topic of academic and practical attention. Due to the large scale and wide impact of newly added green spaces, coal mining subsidence wetland parks have become areas where green gentrification is highly likely to occur. Based on the construction period of "city and lake", the article takes the Pan'an Lake Coal Mining Subsidence Wetland Park in Xuzhou City as the example of the development model of "lake before city" and the Jiulihu Coal Mining Subsidence Wetland Park in Xuzhou City as examples of the development model of "city before lake". And the article uses land use before and after the completion, population structure, and neighborhood relationships as characterization indicators of green gentrification, revealing the process and formation mechanism of green gentrification in different types of lake areas. Specifically, taking 2007, 2013, 2018, and 2023 as time nodes, analyze the process and characteristics of land use evolution within 2km around the lake area. At the same time, use questionnaire surveys and in-depth interviews to analyze the changes in population structure and neighborhood relationships within this range.
The results indicate that green gentrification is an inevitable phenomenon in urban planning and development. Two coal mining subsidence wetland parks have attracted developers to invest in real estate construction through ecological environment improvement and infrastructure improvement, resulting in varying degrees of green gentrification. The "city before lake" development model of Jiulihu wetland park is limited by the existing urban spatial structure, and its gentrification process is slower than that of Pan'an Lake. The overall positive effect of green gentrification in the two lake areas is greater than the negative effect Due to the reserved construction space around wetlands in the "lake first, city later" development model, the degree of land use change around Pan'an Lake is more significant than that of Jiuli Lake.
②Due to the reserved construction space around wetlands in the "lake before city " development model, the degree of land use change around Pan'an Lake is more significant than that of Jiuli Lake. Residential land has increased from 183 hectares in 2007 to 223 hectares in 2023, and public management and service land has increased from 15 hectares in 2007 to 105 hectares in 2023.③The construction of the two lake areas did not lead to large-scale population displacement before and after, but the development of new real estate attracted new immigrants. Under the guarantee of China's land system, farmers who lost their land are resettled in a centralized manner; The newly relocated residents around Pan'an Lake are mainly middle-aged and elderly people with higher education levels, higher income levels, and a need to improve the quality of their residential areas; The newly relocated residents around Jiuli Lake are mainly middle-aged and young people with rigid housing needs.④ Due to the overall relocation of villages in the subsidence area, the construction of both wetland parks did not cause serious disintegration of indigenous social relations. On the contrary, environmental improvement has had a positive impact on improving neighborhood relationships, physical and mental health, and providing employment for Indigenous peoples.⑤ The process of green gentrification in coal mining subsidence areas is jointly promoted by the government, developers, and gentlemanly groups. The government and developers have formed a green growth alliance to meet political and economic needs, respectively, for the purpose of urban governance, land rent, and economic benefits, forming a government led green gentrification operation mechanism.
