| The thesis takes the plants landscape of Yuhuatai Martyrs Memorial Park in Nanjing as the object of study. On the basis of massive collection of information and in-depth investigation into the scene, it applies the knowledge of landscape architecture, ecology, aesthetics and other fields by giving detailed analysis on the plants landscape of Yuhuatai Martyrs Memorial Park on the composition of species, seasonal changes, space structure, aesthetic quality and management measures. This thesis aims at a study on the approach to improving the quality of plants landscape as well as the commemorative atmosphere in Yuhuatai Martyrs Memorial Park to provide a theoretical and practical basis for similar projects. The main content and results of research are:1. The species in Yuhuatai Martyrs Memorial Park is relatively rich, a total of 319 species of vascular plants (including cultivated species), belonging to 86 families 183 genera respectively, in which there are 6 families 19 genera 37 species of gymnosperms, 77 families 161 genera 279 species of angiosperms, 3 families 3 genera 3 species of fern plants, 276 species of woody plants, 13 species of vine plants, 30 species of grasses in total. Various plant species and characteristic plants altogether enrich the color of the whole park effectively.2. The sequence of plants space types in quantity in Yuhuatai Martyrs Memorial Park is semi-open space> open space> vertical space> covering space> completely closed space. As to spatial structure, the plants landscape in Yuhuatai Martyrs Memorial Park has become a fairly complete system of point, line and surface and form an environmental image with clear structure and levels. Meanwhile, the reasonable sequential organization of plants space and the characteristics layout of plants with different functions create different atmosphere for the park, satisfying people's various needs of visiting, mourning and rest.The research also advances a concept of"flow"in order to interpret the continuously changing and complex system of plants space landscape, including the"flow"of ecology, psychology, pattern and color, and the"flow"of poetic imagery.3. The evaluation of plants landscape in Yuhuatai Martyrs Memorial Park by using the method of SBE shows that the scenic beauty estimation(SBE) sequence of plants landscape types in the Memorial Park is gardens > sparse landscape > opening landscape > closing landscape. The evaluation of landscape elements conducted by the application of multi-volume modelâ… shows that the main factors affecting the quality of aesthetic are plants components, life forms, plants density and color changes. Meanwhile, relatively less species composition, relatively simpler level, relatively sparser density and richly varied color will be conducive to scenic beauty improvement.4. According to the current situation and characteristics of the landscape plants in Yuhuatai Martyrs Memorial Park, the following suggestions of landscape construction and management are made: increase the proportion of deciduous broad-leaved trees appropriately, strengthen the protection of existing characteristic plants landscape, increase the using of wild flowering shrubs, enrich the variety of aquatic plants, strengthen the transformation of vegetation in forestry area, increase the excavation of cultural and historical value of old trees, strengthen the richness of plants landscape on both sides of roads and make proper adjustment on the plants landscape around buildings.
