Relying on the background resources such as water, fields, forests, grasses, roads, and villages in the countryside of Shanghai, it makes full use of abundant plant elements to form a plant community landscape with unique local features. This study selected typical villages in three distinct areas of Shanghai (estuarine sandbank plain, eastern coastal plain, and western lacustrine plain) and conducted a detailed investigation of the landscape of four types of green space plant communities: rural courtyard and house side greening, road greening, river greening, and garden greening. On this basis, the analytic hierarchy process is used to construct a plant community evaluation index system, and the expert evaluation method is used to determine the index weights, scoring methods, and standards. According to the index system and the score standard, this article comprehensively evaluated the plant community. The plant community configuration pattern suitable for all kinds of green space was optimized to provide a reference for landscape construction and vegetation biodiversity conservation in Shanghai and its surrounding rural revitalization construction.
