The effective identification and protection of ecological spaces is a fundamental cornerstone for achieving sustainable development and promoting a green society. It plays an indispensable role in ecological protection, resource management, and environmental governance, and is of great significance for the sustainable development of human society. Rapid and scientific identification of ecological spaces provides a scientific foundation for regional ecological protection planning. In this study, we used survey data from the planning and design of forest resources alongside 2017 Landsat 8 OLI remote sensing image to comprehensively analyze forest ecological service functions and ecological sensitivity using the layer-cake model to identify ecological spaces in Nanjing City. The results show that the area of extremely important forest ecological service function zones in Nanjing was 288.57 km², accounting for 3.47% of the total area of Nanjing. The area of highly sensitive zones in Nanjing was 464.39 km², accounting for 7.05%. Considering both forest ecological service functions and sensitivity, the area of core ecological spaces in Nanjing was 692.86 km², accounting for 10.52% of the total area, and the main land use types were woodland and waters. The area of transitional ecological space in Nanjing was the largest, reaching 3 150.29 km², accounting for 47.83% of Nanjing’s total area. This study provides valuable insights for optimizing the layout of ecological spaces and serves as a reference for related research efforts. |
