Due to continuous urbanization and an increasing need to improve living quality, citizens’ pursuit of landscape quality in residential communities is constantly improving in developing countries, e.g., China. This is especially true in the period when citizens were locked down in their home cities or communities in the context of the COVID-19 pandemic. Studying whether the current landscape in residential communities still meets citizens’ needs is of significance as it is crucial for city planners, landscape architects, and city managers. In this study, we used the analytic hierarchy process method to evaluate the landscape quality of five residential communities, using the case city of Yangling, China. In total, 516 valid questionnaires were collected in May 2022. The results showed that good organization of residential roads and pedestrian systems, the rationality of rest facilities, and the hierarchical richness of plants were the most important aspects for residents. Based on these, optimization design strategies were summarized. We hope to provide a reference for future landscape optimization of existing residential communities, especially in developing countries.
