Tree-planting Experiment in City Area by Constructable Tree-planting Technique and Effect of Water Spray
In order to form a cool space in the city area at summer season, the experiments which installs an artificial small forest was conducted at Tatebayashi city in Gunma Prefecture, Japan. 12m×8m area forest was build up near the train station of Tatebayashi city. Trees of various types were used for making the forest. Water spray was used to enhance the air temperature reduction in the foreset. Air temperatures and humidities at several points in the artificial forest were measured. Temperature reduction effects by the artificial forest and water spray were analysed from long-term experimental data during about one month. The questionnaire about the comfortable was also carried out for the citizens. As the results, it was confirmed that an artificial forest and water spray was effective in order to form the cool space into a city area.
