What do you mean by trees along the road?

A row of tall trees was planted on both sides of the wide road.

A row of tall trees are planted on both sides of the wide road, like well-trained soldiers, which embodies the neatness of trees in an anthropomorphic way. Trees on both sides of the road are street trees, which refer to trees planted on both sides of the road and in the isolation belt to block vehicles and pedestrians and form a street view. Street trees have many functions, such as supplementing oxygen, purifying air, beautifying the city and reducing noise. As the network and skeleton of urban green space system, road greening has become the main component of system continuity and plays an outstanding role in directly reflecting urban landscape.

In the selection and application of street trees, urban roads are dominated by deciduous broad-leaved trees, which are shaded by green trees and have beautiful shapes. On the other hand, suburbs and general grade highways pay more attention to maintenance cost factors such as rapid growth, anti-pollution and easy management. Memorial sites such as Yongdao are dominated by evergreen conifers and palm trees, such as juniper, cypress, cedar and masson pine.
