Abstract: Pocket parks are small green spaces that significantly enhance urban livability, particularly in densely populated cities. To leverage this advantage, Chongqing has committed to establishing 100 pocket parks by 2024. This study assesses the landscape quality of six pocket parks in Chongqing’s Dadukou District, employing Scenic Beauty Estimation (SBE) and Analytic Hierarchy Process (AHP). The results of the SBE method identify four main factors—spatial hierarchy, plant diversity, landscape harmony, and color richness—that show a strong correlation with scenic beauty ( R = 0.947, R 2 = 0.897). AHP analysis reveals that landscape function is the dominant criterion, accounting for 66.86% of the total weight, with ecological function and service function contributing 21.44% and 8.82%, respectively. Notably, plant color richness emerges as the most significant factor, with a comprehensive weight of 0.1509, emphasizing its critical role in enhancing visual appeal. Based on these findings, this study recommends increasing plant diversity, optimizing color design to improve visual appeal, and implementing sustainable, low-maintenance strategies. This research integrates both quantitative and qualitative approaches, offering strategies to refine pocket park designs and establish a framework to enhance green spaces in densely populated urban areas, not only in China but potentially globally, promoting environmental sustainability and user satisfaction.
