Table 9: Landscape element proportion of 10 parks with waterbody in the validation stage. lowest (0.93%). Regarding Hardscape ratios, Solanaceous Tree Park ranks lowest (15.17%), with Buzi Park having the highest (39.5%). The average ratios across these parks are approximately 6.6:0.6:2.8 (Softscape:Waterbody:Hardscape). In parks without water bodies, Sanfenpu Park exhibits the most substantial Softscape ratio (95.03%) and Shiquan Park the lowest (61.91%), with the highest Hardscape ratio at 38.09%. The Softscape to Hardscape average ratio here is 8:2. For water body parks, an effective LEP area ratio is approximately 6.5:2:1.5 (Softscape: Waterbody:Hardscape), with Softscape above 65%, Waterbody exceeding 5.5%, and Hardscape kept under 28%. Waterless parks may maintain an LEP ratio of 8.3:1.7 (Softscape: Hardscape) for feasibility. However, the applicability of these findings might be constrained to the context of Taichung City, Taiwan. Parks with water bodies can leverage carbon sinks and aquatic life to achieve carbon neutrality. Specific recommendations include enhancing Softscape in Beitun Children's Park, introducing vertical greenery and permeable paving, adapting design strategies for Taichung Park and Feng Le Sculpture Park to incorporate more trees and reduce high-carbon facilities, promoting tree planting in Shiquan Park, integrating permeable pavement in Gangxing Park, and considering greening options for Shiquan Park to counterbalance its Hardscape dominance.
