A Study on Carbon Dioxide Absorption of Street Tree according to Transplantation Planting Methods for Sorbus alnifolia

Abstract

Enlargement of street tree planting area is the proper and effective solution to reduce carbon dioxide. This solution bases on the ability of carbon storage and uptake by tree metabolism. However, the circumstance of road side has fatal disadvantages in tree metabolism such as growth and maturity because cutting and filling of roadsides cause unnatural soil composition. In this point, early rootage of street tree is the main factor of reducing carbon dioxide. This study aimed to find a appropriate transplantation planting method for sound and rapid rootage of street tree. For the study, Korean Mountain Ash(Sorbus alnifolia) were used for experimental groups. The groups were categorized by three groups such as trees produced on container with mulching treatment, trees produced in outdoor with mulching treatment, trees produced on container with weeding treatment. Each group consisted 10 trees with same size and transplanted in experimental site. Five months after transplanting, each group was estimated the biomass and carbon storage through a direct harvesting method. According to results of the study, the carbon storage of trees produced on container with mulching treatment is 42% more than trees produced in outdoor with mulching treatment. And the carbon storage of trees produced on container with mulching treatment is 19.5% more than trees produced on container with weeding treatment. These results may imply that transplantation of container produced tree with mulching treatment is the most rapid rootage among other groups. The weeding treatment is more effective than mulching treatment for rapid rootage of street trees.

Estimating Carbon Budget from Growth and Management of Urban Street Trees in South Korea

“…Specifically, street trees connect green areas in networks and reduce concentrations of both direct and indirect carbon emissions from their closest sources [15]. As the role of street trees as carbon reduction sources has become increasingly important, numerous studies [15][16][17][18][19][20][21][22][23][24][25][26][27][28] have investigated the efficacy of this strategy worldwide.…”

Improvement of the Planting Method to Increase the Carbon Reduction Capacity of Urban Street Trees

“…Studies in Korea and overseas on carbon uptake in greenspace of streets (Jo and Cho, 1998;Jo, 1999;Jo et al, 2003;Park and Kang, 2010;Kim et al, 2011;Kim, 2013;Russo et al, 2015;Park, 2015a;Park, 2015b;Tang et al, 2016;Jo et al, 2018;Zhao et al, 2018) have been conducted since the late 1990s. Recently, Jo (2020) and Jo et al (2020b) have quantified the carbon uptake of street trees in some cities of Korea and provided planting guidelines to maximize it.…”
