The Research On The Plant Landscape In Tianjin Binhai New Area

With the rapid development of the urbanization process,coastal cities develop more quickly, and the the construction of landscape in coastal cities is paid more and more attention.Scientific and rational way to create a landscape of plants, can build a good image of the city, but also provide a sound ecological, beautiful, friendly and pleasant, the rich local cultural characteristics of the environment for the urban residents. Therefore, the study of Tianjin Binhai New Area plant landscape plays an important role on the sustainable development of Tianjin Binhai New Area plant landscape and plants landscape construction in modern urban.The object of research mainly concentrates on Tianjin Binhai New Area,and 62 relatively stable plant communities have been investigated and analyzed. Firstly, the paper surveys and analyzes plant composition, halophyte composition, ornamental characteristics, ecological structure of Tianjin Binhai New Area plant landscape. Secondly, To establish the reasonable evaluate system by AHP,and evaluate the palnt landscape of Tianjin Binhai New Area from three aspects:the the ecological value in plant landscape,the aesthetic value in plant landscape and the social effect in plant landscape.Thirdly,sum up the advantage and disadvantage to Tianjin Binhai New Area plant landscape,and than the suggestions to optimize the plant landscape are put forward.Finally, the paper create some ideas to the plant configuration of Tianjin Binhai New Area, in order to provide the basic ideas for the construction of Tianjin Binhai New Area plants landscape.The results show as follows:l.It totally have 67 species which belong to 24 families and 37 genera in 62 plots. The plants is concentrated on few and single families in sample plots. And Rosaceae, Leguminosae, which are world's big families occupy a relatively large proportion.2. The plant species are abundant in the communities of Tianjin Binhai New Area, but most types of applications is still not widely. Whether arbor or shrub layer, the use of high frequency mainly concentrates on a few species.3. There are 45 species halophyte in the 62 plots,and take 67.16 percent in all species,including the 19 obligate halophyte and 26 facultative halophyte. 4. There are 31 mainly ornamental flower, which is focused on the shrub layer. There are 19 ornamental fruit plants, which is focused on the arbor layer and shrub layer. There are 25 kinds of colored foliage plants, and the most of colored foliage plants is autumn leaves plants.5. The structure of plant communities is multiple structure combined with arbor,shrub and herbaceous on the whole in communities,taking 54.84 percent in all types.6. To establish the reasonable evaluate system by AHP,and then confirm the evaluation factors and the weight ratio,in order to evaluate the palnt landscape of Tianjin Binhai New Area from three aspects:the the ecological value in plant landscape,the aesthetic value in plant landscape and the social effect in plant landscape.7.The result of comprehensive evaluation showed the communities is concentrated onⅢ,Ⅳ,Ⅴ-gradelandscape quality, therefore,Tianjin Binhai New Area in plant composition and the creation of the landscape need to be further improved.8.Sum up the advantage and disadvantage to Tianjin Binhai New Area plant landscape,and there are some suggestions to optimize the plant landscape including enriching the halophyte species;simulation of zonal communities;enriching the native plants and the plant community structure.9.To analysis the various factors and the principles of the design of Tianjin Binhai New Area Plant landscape.Finally, the paper create some ideas to the plant configuration of Tianjin Binhai New Area, in order to provide the basic ideas for the construction of Tianjin Binhai New Area plants landscape.
