Background and objective: This study was conducted to develop Connecting Forest planting technique suitable for urban structure and target site conditions on Banpo-daero Street in Seocho-gu. Methods: Through simulation analysis of planting techniques by type (computer climate model: ENVI-met), the streettypes were classified into the following categories: bare ground type (1), currently planted with Platanus occidentalis(square pruning) (2), a type that can realistically create a strip green (3), and a type that grows the tree canopy and appliesPlatanus occidentalis and a strip green in the center of the road (4). Results: In the case of creating a 2-meter-wide band green on the existing street trees in the first row, and multi-layeredvegetation using the step-by-step arrangement method of small tree + shrub + herbaceous plants, the temperature of upto 0.15°C rise in the roadway area and the temperature of up to 0.12°C went down in the sidewalk area, and PMV (PredictedMean Vote) was reduced by up to 1.32 in the multi-layer trench planting area. Particulate matter was concentrated,resulting in an increase of about 40~80㎍/㎥in roadways and sidewalks. In the case of the ideal planting arrangement of theroute applying the original tree tree tree street + the green belt 2m + the central green zone, the effect of reducing themaximum 1.6°C in the roadway area and 0.3°C in the sidewalk area was shown, and the result of lowering the temperaturethroughout the target area was derived. arise from street trees, trench planting and trees in Green Area at the Center Linethe concentration of particulate matter in the roadway area increased to about 150μg/㎥, and the concentration ofparticulate matter in sidewalks and residential areas decreased. Through simulation analysis, we planted street trees withlarge trunk widths that are favorable for shade formation (Platanus occidentalis) and maintained the unique tree shape, oval,rather than square pruning, and the composition of the strip greenery consisted of multi-layered plantings based on theterraced layout method by introducing tree species with excellent particulate matter reduction capabilities. Conclusion: This study is meaningful in analyzing the function of connecting forests, which play an important role in urbanwind ventilation forests, which are created as a solution to improve the urban environment, such as reducing particulatematter in the city and mitigating heat waves, and suggesting planting techniques that can improve their function.
