| Plant is one of the important elements of landscape,and it’s the most viable landscape landscape elements, garden plants Landscape addition to forming a better viewing, but alsosubserving both the ecological, environmental and even economic benefits and other aspects. However, due to the climate and environment, some cities’ landscape in the fall and winter is relatively monotonous, especially in cold winter weather, many cities even have no landscape, resulting in decreased attractiveness of the city.Therefore, urban plant landscape in fall and winter seasons must be resolved. Taking the main urban areas of Xi’an as the research object, using the method of sampling survey, Sampling select somebetterautumn and winter viewing greenland in Xi’an, survey and record the plants that with landscape value and the landscape performance of them,and through the method of literature searching,comparative analysis,explore the autumn and winter plant and their landscape performance of Xi’an,investigate the characteristics of the regional landscape plant landscape configuration mode, summed up the principles and strategies for Xi’an fall and winter plants and their landscape.This paper analyzes the fall and winter seasons urban landscape garden plantslandscaping need to meet four principles: the principle of scientific ecology, aesthetic principle, the principle of cultural connotation and function of practical principles, and put forward that the layout form of garden plants autumn season is also divided into natural style and rules style. Through the survey, statistics out 292 kinds of plants which come from 72 familys 156 classe that can be used in Xi’an,of which 90 kinds of evergreen plants, 107 kinds of colored leaf plants, 29 kinds of flower plants, 87 kinds of fruit-effect plants, 22 kinds of stems-effect plants, in addition to some posture shaped plants, buds viewedplants, these plants and their ornamental value and application forms are enumerated.The survey also found that there are some problems of landscape performance of these plants:firstly the landscape is monotonous, few lively; the second is not focused on the effect of local micro-climate; thirdly the use of plants’ value in winter is inadequately, the plants commonly used in the type of urban greening are not to 50%.For the fall and winter of Plant Landscape in Xi’an, the paper application recommendations are proposed different types of ornamental plants, and proposed to the "three ways by plants" to rich species diversity and "four ways by measures" to ensure that the landscape diversity, through the two ways to enhance the fall and winter plant landscape effect in Xi’an. Finally, the article recommends some native plants with autumn and winter landscape value, some landscape plants with environmental features, and plant communities withgoodecological benefits, with a view to Xi’an and even Shaanxi Province of the future plant landscape design and conception provide a theoretical basis and guidance. |
