Species Diversity and Decorative Features of Plants Used in the Landscaping of Hanoi
Journal Title: Lesnoy Zhurnal (Russian Forestry Journal) - Year 2021, Vol 10, Issue 5
Abstract
The article presents the results of studies on species diversity and decorative features of plantations in Hanoi. The relevance of this research is justified by the failure to meet the standards of landscaping in the city in accordance with global recommendations and standards. The dendroflora of central Hanoi has 304 species (including varieties and forms) belonging to 253 genera and 104 families. The leading families are Fabaceae, Arecaceae, Asteraceae, Apocynaceae, Bignoniaceae, Meliaceae, Verbenaceae, Myrtaceae, Moraceae, Caesalpiniaceae, Rosaceae, and Magnoliaceae. The Fabaceae family predominates by the the number of genera and species; and is followed by the Moraceae family. The greatest species diversity is observed among trees (151 species – 49.67 % of the total number). The most commonly used species in the urban gardening are Peltophorum pterocarpum, Delonix regia, Khaya senegalensis, Chukrasia tabularis, Ceiba pentandra, Pterocarpus macrocarpus, Hopea odorata, Dracontomelon mangiferum, Alstonia scholaris, Lagerstroemia speciosa, and Terminalia mantaly. Evergreen species predominate among plantations of Hanoi; while deciduous (including shrubs and trees) have a smaller proportion. Of 151 species of trees, 70 are classified as decorative. Shrubs and herbs are inferior to trees by the number of species (58 species each – 19.08 %). Palm trees are the least numerous – 11 species (3.62 %). The decorative features of the main species have been determined. A list of trees with 3 or more decorative features, shrubs and herbs with 2 or more decorative features was compiled. In order to create a unique urban landscape in different seasons of the year it is recommended to use the species included in this list.
