Abstract :
In the design of urban green space, it is important to rely on the selection of native species, considering their greater compatibility with the climatic conditions of the region, easier care and lower maintenance costs. The basic selection of plants in the urban green space should be based on some factors such as aesthetics, environmental, ecological and natural requirements, functional characteristics, resistance to pollutants, tolerance to pollution and adaptation to special weather conditions. The aim of the present research was to investigate the aesthetic factors in the selection of trees and shrubs to be cultivated with an emphasis on native ornamental species in the urban green space of Langroud city in Gilan province, Iran. A field study was conducted on 12 species (Cupressus sempeivirens var. horizontalis, Parrotia persica, Zelkova carpinifolia, Quercus castaneifolia, Thuja, Callistemon citrinus, Fraxinus ornus, Crepe myrtle, Citrus aurantium, Alnus glutinosa, Acer cappadocicum and Ginkyo biloba) and their aesthetic characteristics were recorded with the help of observation in nature. By selecting and determining 9 aesthetic indicators (creation and production of shade, beauty of the trunk, beauty of the branching pattern, beauty of the leaves, beauty of the landscape, shape and cover of the tree crown, scale of plants, pruning ability and habit to sucker production) and asking for opinions from experts in the form of questionnaires designed based on the collected information, trees and shrubs were evaluated using the AHP hierarchical analysis process and analyzed by Choice Expert software. The findings of this research showed that among the investigated species; Z. carpinifolia (containing the highest parameters in all traits), C. sempeivirens and A. glutinosa had the highest desirability, and Callistemon citrinus, Crepe myrtle, and Ginkyo bilob had the lowest desirability. In the general ranking of trees and shrubs, Z. carpinifolia, C. sempeivirens and A. glutinosa ranked first to third with the scores of 0.238, 0.197 and 0.1۵6, respectively. Identifying suitable trees and shrubs for planting in each area can be of great help to decision makers and designers of urban green space development.
