Application Of Trees In The Garden Of Seasonal Variation Characteristics

Trees seasonal changes is a special kind of tree responses to climate adaptation and a manifestation of the biological environment. It will change with the seasons presenting different views. In this study, based the research conducted in Northwest A&F University,we used the methods of phenology, ecology, landscape aesthetics and relevant theories to observe,record and field camera 30 kinds of trees and leaf, flowering, fruit coloration of leaf discoloration on other aspects in campus Northwest A&F University, and from the seasonal statistical analysis of its leaves, flower color, fruit color and other aspects, master the law of development of trees,habits and seasonal ornamental features. Combined with the observation trees phenological recording data and examples of photos, organize for the common 30 kinds of trees and use of Microsoft Project2010 Gantt chart, draw a phenological patterns and ornamental phenology patterns, by analysising Wesfarmers campus English Corner seasonal Situation, configurations, tree growth and management situation, objective evaluation of English corner seasonal landscape, proposed the existing problems and gives recommendations and the corresponding optimization. Eventually, according to seasonal, configurations and other factors, we screened out seasonal characteristics significantly and adapted species off regions for the future garden workers during seasonal reference when selecting trees, but also for the wealth of species in the Guanzhong area garden diversity, landscape diversity provide a reference.According to phenological observations, statistical results are as follows: In the investing 30 kinds of trees, there are 16 families and 23 genera and 10 high frequency applications. there are 15 kinds of common road greening tree species.Species richness and species numbers,are higher than the average level of the majority of cities in the country.(1) There are trees on behalf of the family in campus Northwest A&F University: Rosaceae, Oleaceae, Magnoliaceae, Bean, Caprifoliaceae, etc. life aspects of the trees, Joe, dominant shrubs.(3)On the ornamental characteristics, Flower, fruit, autumn leaves, spring leaf tree species gradually diminishing, the number of design and color is given priority to with red, white, yellow, purple, in turn, Spring flowers concentrated in late march- early April, mainly in red at most; The fruit color is given priority to with red, black, yellow, fruit tree species from may have interval in October, fruiting is longer, but in September and October are the most concentrated; Autumn leaves is given priority to with red, yellow, although a few kinds, but the number of many, and longer duration of disease, mainly concentrated in late October-in late November; Spring leaf ornamental concentrated in early march- in the middle of April, give priority to with purple, dark sustainable 2-3 weeks, color shallow only last 7 to 10 days.(4)Campus trees the seasonal characteristics of Northwest A&F University:spring phenological phenomena of the highest frequency, is given priority to with lamina, flowering; Summer phenological phenomenon occurrence frequency is low, most of the trees grow slowly, a small flowering trees; autumn phenological phases to achieve higher frequency, give priority to with mature leaves, leaf color, fruit; in winter the lowest frequency phenological phenomenon, evergreen, view branch tree species.(5) Northwest A&F University campus trees by combining color season characteristics as follows:spring is given priority to with patches of powder, white and yellow flowers, and occasionally some purple spring leaf; Summer in a shade everywhere is given priority to, with a small amount of red, white, purple, blue, yellow spots; between give priority to with yellow autumn leaves fall, with some red fruit and autumn leaves in the composition of plaque; winter is given priority to with branches brown and dark grey.
