Study On Landscape Design And Plant Configuration Of Suburb Green-land In Xi’an

With the speeding up of urbanization in recent years, urban ecological construction is more and more concerned by people, which has become the main part of tourism and its development trend. So the urban ecological construction of surrounding is a great significance of the development of ecological tourism development and planning. The article chose xi’an suburban regions as its object. From the perspective of ecology, the region geography, natural conditions and using status of suburban green-land were analyzed, and the specific landscape, collocation of greening species and the special design of tree species were designed. Strive for providing the theory and practice basis on suburb ecological green-land design. The main results were as follows:1) Low maintenance cost, high ecological benefits, high service requirements and high quality landscape was the goal. In the ecological system of outskirts, different landscape would have different interpretation. Suburban ecological design attached great importance to the protection of natural environment, and established ecological function and good landscape pattern, also promoted the efficient utilization of resources and recycling.2) Landscape forms of natural ecological was simulated by the concept of nature; Plants stereo space was simulated by the natural growth of canopy line, landscape foil prospects background on mutual echo, and interdependence on the ecological habit, which could form stable and rich planting space. Combined with the plant growth in different landscape terrain, the whole green space formed richer stereo space, and have a sense of rhythm.3) The choice of tree species was given priority to the optimum principle of tree, the main landscape nodes chosen by large and full tree of local species as the main ornamental tree species, which could command in landscape area space. Creating of the ecological system and the rainwater harvesting system should be considered in the process of tree species selection and configuration.
