Abstract

This study was conducted to understand the change time-series of landscape trees planted in apartment complexes and to predict the demand for pine trees among landscape trees. From 2003 to 2020, the average number of trees used in apartment complexes in the Seoul metropolitan area were 51, and various types of trees were used in the late 2010s compared to the mid-to-late 2000s. The average planting quantity was 149,567trees/1 complex, and the time series change was not noticeable. Comparing evergreen trees and deciduous trees, there was a difference between the planted species and the planted quantity. Compared to evergreen trees, deciduous trees were planted with relatively diverse species. Evergreen trees were planted in large quantities, with fewer varieties than deciduous trees. The types of trees and shrubs consist of a ratio of 6:4, and shrubs accounted for 97.6% of the total planting volume. Compared to the amount of planting, the varieties of trees planted are not diverse. When analyzing the planting status of pine trees with high preference and use value of landscaping trees, the planting volume tends to increase, and in particular, the planting ratio of large pine trees is increasing. Predicting the demand for pine tree planting in apartment complexes will continue to increase the amount of planting, especially with special trees with a root diameter of 40 cm or more. In response to these changes in demand for landscaping trees, a strategy is required to discover and produce various plant materials. In particular, since the demand for large pine trees is continuously expected to increase, production management should be carried out so that pine trees with the shape and specifications required by the market can be supplied.
