通过在4个季节对上海市11个美丽乡村进行实地调查 , 统计分析获得的实景照片和观测数据, 总结归纳出应用的多年生草本种类共有30科52属62种. 其中, 禾本科、菊科、天门冬科植物占比较高; 乡土植物占比较低, 仅15.63%. 植物景观存在的问题有优势物种单一、景观效果雷同、植物生长状况不佳等. 利用聚类分析对调查的多年生草本的综合性状进行划分, 筛选出表现较差的种类的替代种, 优化植物群落配置, 为改善上海市乡村植物景观提供理论基础.

Based on a field investigation of eleven villages in Shanghai across four seasons and statistical analysis of photos and observation data, 62 perennial herbs species, belonging to 30 families and 52 genera, were identified. Gramineae, Compositae, and Asparagaceae accounted for the majority of species observed; meanwhile, native plants accounted for a relatively low proportion, representing only 15.63% of the total. Challenges for the plant landscape include monotonous dominant species, similar landscapes, and poor growth conditions. Cluster analysis was used to classify the characteristics of the investigated perennial herbs and to select potential substitutes for underperforming species. The data can be used to optimize the allocation of plant communities and to provide a theoretical basis for improving the rural plant landscape of Shanghai.
