Investigation And Research On Green Situation In Xilinhot City Square

This paper selected three kinds of square, which are able to stand for the greening of Xilinhot’s square comprehensively, by visiting and investigating Xilinhot. These three sorts of square are entertainmen square(Xilin Square), cultural square(Mongol-yuan Cultural Square, Beizi Temple Square) and traffic square(Zhanqian Square) as respondents, fully discussed tree species and quantity, composition and structure of tree, growing condition and configuration status of plants, ornamental characters and seasonal phenomena, in addition, the paper pointed out the problems that is existed of the greening of Xilinhot’s square at present. At the same time, it put forward some feasibility suggestions.According to the survey result of the Xilinhot square, The number of greening trees is totally 36, including 3 casuarinas,19 deciduous trees,2 evergreen shrubs,12 deciduous shrubs, they mainly distribute rosaceae, oleaceae, salicaceae and so on. The Rosaceae is at most, but the varieties of plants are not plentiful. In the meantime, the number of the native seeds of trees is 9, they accounts for 25.00% of all the investigated trees. The squares have 27 exotic trees, accounting for 75.00% of all the seeds of trees. It shows that the greening trees of Xilinhot’s square widely based on exotic trees, but indigenous plants are relatively fewer. The average proportion of shrubs species of Xilinhot’s city square is 1:0.65, the average quantity is 1:0.83. The research result indicated that the most arbors and shrubs species are distributed unreasonably, the type and quantity of shrubs are used less. By investigating the four city squares, we found that the average ratio of evergreen and deciduous species is 1:6.20, the average quantity is 1:1.24, which shows that the proportion of evergreen and deciduous species is unreasonable. Because of the fewer tree species, and individual tree species are used too much in some squares, resulting in the richness and diversity of squares’ plants are universally poor. The most greening tree species of the four squares are well-grown, the ordinary are in small numbers and there are only individual tree species growing in poor conditions. In the way of plant configuration, it is mainly based on opposite planting, linear planting, scattered planting,clump planting, block planting, with the combination of arbor-grass, shrub-grass, arbor-shrub-grass, and form a allocation formation of formal style, natural style and combined type, in addition, it combines with the surrounding buildings and Mongolian elements, which are able to form certain visual effect. The flowering ornamental plants and other kinds of tree species are used more widely in the four squares, the leaf, fruit and evergreen tree species are relatively used less widely. The seasonal phenomena of spring and summer are richer, however, the ornarnental plants of autumn and winter are relatively fewer, and the plants landscape are poorer, which caused the seasonal phenomena of plants in the squares are unconspicuous.Based on research and analysis, the greening situation of entertainmen square is relatively better, the cultural squares’ greening situation have own advantages and disadvantages, nonthing to choosing between them, houerer, the greening situation of station square is relatively better. This paper based on the above existing problems of greening situation of Xilinhot’s square, having put forward some relevant solutions. The author hope that it will provide some theoretical basis for the greening construction of squares of Xilinhot and the surrounding cities by studying this paper in the future.
