Objective/Meaning Based on the multi-dimensional collaborative perspective, the ecological, cultural, social and sustainability of mining brownfield reuse were comprehensively evaluated. And the hierarchical reuse strategies to maximize the comprehensive benefits of “ecology-culture-society” in mining brownfields were explored, aiming to provide the systematic theoretical support and practical exploration methods for the remediation and reuse of mining brownfields in the coastal areas of subtropical mountainous and hilly areas in China.
Methods/Procedures From the perspective of landscape architecture and based on the multi-source data, the study attempted to quantitatively evaluate and classify the spatial ecological service, social service and cultural service functions of mining brownfields in Jinjiang City from the multi-coordination dimension of “ecology-culture-society”, and then the comprehensive reuse of mining brownfields was explored.
Results/Conclusions The results showed that: (1) The classification results of mining brownfields based on the ecological service dimension: the development and construction area accounted for the largest proportion, followed by the general ecological restoration area, important ecological restoration area, and priority ecological restoration area. (2) The classification results of mining brownfields based on the cultural service dimension: the cultural resource protection and development area accounted for the largest proportion, followed by the cultural resource protection area and the cultural resource development and construction area. (3) The classification results of mining brownfields based on the social service dimension: the medium social demand area accounted for the largest proportion, followed by the low social demand area and the high social demand area. (4) The classification results of the “ecological-cultural-social” comprehensive service functions: The area designated for the general restoration investment accounted for the largest proportion, followed by the important investment restoration investment areas, natural restoration areas, priority investment restoration areas, and the development and construction areas. Based on the perspective of “ecological-cultural-social” synergy, the importance of ecological function, the richness of cultural resources and the urgency of social needs in mining brownfields were comprehensively considered, in order to realize the dynamic balance and synergistic enhancement of space use in three dimensions after the reuse of mining brownfields. Based on the research results, the countermeasures and suggestions for zonal management and multi-objective coordination were put forward, including taking scientifically sound technical measures to protect the mining environment and transforming the mining brownfields into the ecologically resilient public spaces, in order to promote the transition of mining brownfields from an “ecological burden” to the sustainable spatial carriers that integrated ecological, cultural and social functions.
