Study On The Application Of Ornamental Tree Species In The Park Environment Of Tianjin Urban Area

Ornamental fruit trees belong to ornamental plants in horticultural crops,and their fruits have good ornamental properties.Compared with the effects of greening and beautifying the environment of common garden trees,their flowers and fruits can also play a unique role in aromatizing and fruiting the urban landscape,strengthening the effect of seasonal changes and increasing the biodiversity of Tianjin city.This research used field investigation and analytic hierarchy process to visit Tianjin urban parks for many times,and recorded the application of fruit tree species,including use type,growth status,configuration form,etc.In order to provide a more scientific and systematic theoretical basis for the application of fruit tree species in Tianjin,the observation data were collated and studied.The results of the investigation combined with horticulture,landscape gardening,landscape ecology and other disciplines are as follows:First,the species,application number,growth status,planting patterns and repetition rate of the existing fruit trees in Tianjin urban parks were investigated,summarized and classified,and a total of 78 species,including 35 families and 50 genera,were obtained.Second,the history and cultural connotation of the application of fruit tree species in greening are excavated and summarized to optimize Tianjin’s urban landscape and create a more cultural landscape environment.Third,the analytic hierarchy process is used to comprehensively evaluate and sort 50 kinds of fruit trees commonly used in Tianjin,so as to fully explore high-quality varieties and make them play an advantage in urban landscaping.Fourth,Select the ornamental fruit tree species with high comprehensive score for popularization and planting.Aiming at the selected typical parks,combine the planting of the ornamental fruit tree species with different functional zones and garden elements,and put forward its specific optimal planting application method.Combine the characteristics that flowers,fruits and leaves can be enjoyed,enrich the plant planting types in the landscape,and create a green environment with considerable scenery in the four seasons.
