Prioritizing Ecological Restoration and Reuse Zoning for Mining Brownfields at a Whole-Area Spatial Scale Within a “One Health” Framework: A Case Study of Longhu Town, Jinjiang City

As an important part of territorial ecological restoration, existing research on mine ecological restoration largely focuses on individual mine restoration projects from an engineering perspective or the identification of restoration priorities from a purely ecological viewpoint. There is little consideration of integrated decision-making for mine ecological restoration at a whole-area spatial scale, and a spatial prioritization framework that simultaneously integrates ecological, habitat, and health-support dimensions remains absent. This study introduces a One Health framework, taking 169 mining brownfields in Longhu Town, Jinjiang City, Fujian Province as the study objects. Based on a whole-area spatial scale, ArcGIS (10.8) spatial analysis was conducted to construct a three-dimensional evaluation framework of environment, species, and health support from the three dimensions of ecological sensitivity and landscape visual sensitivity, bird habitat suitability, and the spatial provision of health facilities. The Analytic Hierarchy Process (AHP) was then combined to identify ecological restoration priorities and reuse zones, further exploring strategic guidance for the ecological restoration and reuse of mining brownfields oriented toward a One Health framework at the whole-area spatial scale. The results show that the 169 mine brownfields are concentrated around stone processing areas. Among them, 21 sites are prioritized for environmental restoration, 67 for bird habitat suitability improvement, and 93 for enhancing health facility provision; these are ultimately classified into three comprehensive restoration zones. This study can provide decision support for the differentiated restoration, reuse zoning, and spatial governance of mine brownfields within a whole-area spatial planning system.
