A Research Over The Landscape Plant Planning Of Changsha City

With the development of urban area and the improvement of people's living standards, the planning of landscape plant is getting increasingly important, and the related authorities is attaching more and more importance to it. Based on preliminary theoretical analysis of planning of landscape plant, a research was conducted on the planning of landscape plant of Changsha City and some achievement is made. The achievement of the research is expected to provide theoretical and practice guidance for the future planning of landscape plants. The achievement of the research is mainly as follow:Preliminary theoretical analysis indicates that normally there can be many options for planning of landscape plants, whereas some principals should be followed: principal of ecology, principal of aesthetics, principal of adaptability and principal of security. Arrange the local plant species as the majority, while non-local as the minority. Mind the way space setting of plants: for the top tier plants, they need more sunshine, the middle tier ones need less, the bottom tier ones need least sunshine. Do not allow single botany community; For the principal of aesthetics, mind the unified diversity, reconciliation and contrast, balance and stability, the rhythm proportion and scale. The aesthetic expression should be presented, the function of the building should be specified so as to make scientific and artistic aspects highly integrated.The analysis on the planning of landscape plants of Changsha City shows the basic features below: insufficient species of plants; unbalanced Greenland quality, with the newly constructed landscape Hexi of better quality and Hedong of poor quality; excessive application of shrubs, large proportion of native plants; Lack of continuous repair and maintenance, with naked land being found among the greens.Through the analysis of plant material, the results indicate that : the choice of plant material should be based on the type of structure, location, physical volume size, color, materials, etc. These factors are different thus the plants with different type, texture, color are also different. At the some time attention should be paid to various kinds of relation ships between the plants. At the some time attention should be paid to various kinds of relation ships between the plants. The best green structure should be arbor, shrub, grass and flowers mixed in multi-layer. In practice, the green...
