The practical application of street trees should be based on the road construction standards and the specific circumstances of the surrounding environment, determine the appropriate tree species and varieties, and choose the appropriate tree body and tree shape. If there are restrictions such as power and communication lines above the planned planting belt, trees whose final growth height is lower than the elevation of overhead lines should be selected to save the cost of regular pruning. If the maintenance of trees can maintain a high level, we can choose tall trees, adopt correct pruning methods and avoid the restrictions of overhead lines, so as to obtain satisfactory use results. In addition, when planting plastic, the branches of trees should be high enough so as not to interfere with the normal passage of passers-by and vehicles, and not to block people's sight. Especially in areas with small turning radius and poor line of sight when turning, more attention should be paid. The selection of tree size should be appropriate and should not exceed the requirements of the proportion with the architectural landscape on both sides of the street. Its size and growth form should meet the specific requirements of design and stand the test of time. The height of street trees on the same main road should be relatively consistent, and it should be more than 3 to 3.5 meters in the area where the road surface is narrow or large vehicles pass. In a wide road or pedestrian street, it can be reduced to 2.5 to 3.0 meters, and the tree species with small branching angle can be appropriately reduced, but not less than 2 meters. The size of the tree should be as neat and uniform as possible to avoid the aesthetic effect and management inconvenience caused by uneven height and different sizes and thicknesses.

Of course, it is best to get approval from the relevant departments, but it doesn't matter if there are not many kinds ... no one will care about these ... all kinds of trees beautify the city (the plan is given above). Maybe someone will thank you. ...
