Preliminarily Study On Green Plant Landscape Buiding In Xi'an City Park

In this paper, green plants landscape of City Park, small parks, and open squares in the area of Xi'an city is the main object of study. The existing plant species in Parks have been investigated, and the composition mode of the existing park plants landscape has been investigated; by the view of ecology, botany, environment esthetics, the distribution of green plants landscape was discussed, and the distribution mode of green plants landscape in Xi'an Park was suggested. The conclusions are as follows:1,There are 87 branch 445 kinds park plants altogether in Xi'an city area. Including eight types such as the deciduous broad-leaved trees,Evergreen broad-leaved trees, evergreen coniferous trees, deciduous shrubs, evergreen shrubs, vines, herbs and aquatic plants. But the proportion of vine plants species is smaller, and the recently introduced plants are more, and native plants are also underutilized.2,Plants pattern built in the region of Xi'an are a total of 7 species, namely:①Planting pattern of a single plant, its characteristic is the field of vision is open, the tourist enters the park easily, but the worst effect is environmental improvement;②Planting pattern of trees and herbaceous plants, this pattern is not only shade, but also the tourist enters the park easily, so it's most commonly used in the park;③Planting pattern of trees and shrubs, This pattern's ecology improvement ability is better, the landscape performance is also better, but not to be suitable for tourist to enter, so it's used in the function district of scenic area in the transition zone;④Planting pattern shrubs and herbaceous plants, this pattern has the open field of vision, but the tourist enters the park difficultly, so it's used in the place which is the park entrance or is inconvenient for the big tree transplant;⑤Planting pattern of trees and shrubs and herbaceous, this pattern is the best for landscape effect and the ecological benefit, but is often cannot be used as a result of environmental condition limitation.⑥Planting pattern vines plants vines plants, This pattern is ideal scaffolding for the green of wall or a model construction, and is often used both inside and outside the park view of visual impairment or shelter of rigid construction in park;⑦Planting multiple patterns of Trees, shrubs, vines, herbs and aquatic plants, this pattern is advantageous to enrich the water landscape, but is only limited to water landscape building. The plant disposition divides into several different kinds from the different angle:①From the aspect of plant communities function types, there are five types of Watching, environmental protection, cultural, popular science, production, and watching is the most common type.②From the aspect of plant landscape disposition, there are five kinds of open, half open, covered, enclosed, and vertical, and the open and half open kinds are more popular .3,Green plant landscape features of Tang Paradise has been analyzed and summarized:①Focus on creating plants landscape to reflect the various culture;②The landscape plants of revetment contrast lake water;③The open lawn and landscape connected with the outside world to the jungle.The deficiency is:①Lack of rocks in plant landscape;②Plant landscape between the green space and the lake pond's transitional is insufficient, the lake pond aquatic plant are few;③On garden road point plants are flaw, but flinty transition.4,Suggestions which are proposed to Xi'an green ground plant landscape building:①Through the modern garden's technique skill in formally, park green plant landscape building fully uses the color effect of the plant population, and forms the compound green by the union of the tree,bush,lawn. Using the different forms of the sparse forest lawn,the pure forest or the mixed forest combines into the different green space style.②Plant building in each tours transition region unifies the plant's biology characteristic match of the plant density distribution or the vine and hook punctures plants to carry on the flexible function district, causes the tour area covered with the green grove, and achieves the goal of the ecology landscape gardening.③Choosing indigenous plants as main material as far as possible and appropriate introduction of improved plants varieties lead to enrich the park green hue and seasonal.④Take advantage of seasonal changes of plants in order to increase the changing landscape of color and space. The flexible usage between the evergreen and deciduous trees, color leaf trees, and the coordination with flower, foliage, plants ,to make distinct seasons plant landscape, and to make the overall landscape features more gorgeous.bountiful .picture -sque and beautiful.⑤More wild shore water hygrophytes should be transplanted around the lake pond, and the aquatic plant should be artificially transplanted in the lake pond. The stone landscape area similarly should consciously dispose the native wild plant which is interest and unexpected.⑥The theme park campus should dispose its subject implication related plants as far as possible. Park road junction points and the isolation outside the park are suggested planting to soften hard isolation. Under different environment and conditions, with the generally match of the tree, bush and grass plants, the green landscape layout of'three quarters of flowering, evergreen'will be created. Using the different planting form to coordinate the different environment, make the green space with various regions form the harmonious unification as whole, and form the sustainable development of the park green ground plant landscape finally.
