The concept of "Carbon Neutrality" has gained widespread recognition lately. Urban green spaces offer valuable opportunities to provide natural public areas and mitigate carbon emissions, especially in high-carbon-emission cities. The primary objective of this study is to investigate the carbon footprint, resilience levels, and optimal landscape area ratios of various parks. Additionally, it explores the relationships between Landscape Element Proportions (LEP), the Normalized Difference Vegetation Index (NDVI), Resilience Indicators (RI), and the carbon reduction benefits associated with carbon neutrality (CN). Six parks were assessed for resilience, NDVI, LEP, and CN values, with Pearson correlation analysis conducted. The results revealed that parks with or without waterbodies exhibited ideal LEP area ratios of 6.5:2:1.5 (Softscape: Waterbody: Hardscape) and 8.3:1.7 (Softscape: Hardscape), respectively. Enhanced Softscape and reduced Hardscape proportions in parks correlated with increased NDVI and CN, contributing to carbon neutrality. NDVI exhibited a positive correlation with Softscape percentage and a negative correlation with Hardscape percentage. Conversely, CN demonstrated a negative correlation with Hardscape percentage and a positive correlation with Softscape percentage. Specific recommendations were proposed, suggesting Softscape should constitute over 65%, and Hardscape should be under 15% in parks with water bodies. Waterless parks are advised to maintain a Softscape ratio exceeding 83% and a Hardscape ratio below 17%. Future park design, maintenance, and improvements should incorporate these findings for carbon neutrality. Finally, the study extended to assess the LEP of 22 additional parks, proposing enhancement strategies and validating the suitability of the ideal LEP area ratio.
