The Ideal Strategy of Carbon-Neutral for Park Landscape Design: A Proposal for a Rapid Detection Method

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. 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. 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%. Finally, the study extended to assess the LEP of 22 additional parks, validating the suitability of the ideal LEP area ratio.

本研究之主要目标在于探讨各类公园的碳足迹、抗逆性水平以及最佳景观面积比。此外，本研究还探究了景观元素比例（LEP）、归一化植被指数（NDVI）、抗逆性指标（RI）与碳中和（CN）相关联的碳减排效益之间的关系。对六个公园进行了抗逆性、NDVI、LEP和CN值的评估，并进行了皮尔逊相关分析。研究发现，无论是否有水体，公园均表现出理想的LEP面积比为6.5:2:1.5（软景观：水体：硬景观）和8.3:1.7（软景观：硬景观）。公园中软景观比例的增加和硬景观比例的减少与NDVI和CN的提升呈正相关。NDVI与软景观百分比呈正相关，与硬景观百分比呈负相关。反之，CN与硬景观百分比呈负相关，与软景观百分比呈正相关。研究建议，在有水体的公园中，软景观应占超过65%，硬景观应低于15%。对于无水体的公园，建议保持软景观比例超过83%，硬景观比例低于17%。最终，研究扩展至对22个额外公园的LEP进行评估，验证了理想LEP面积比的适用性。
