| Outline of Final Research Achievements |
Urban forestry plays a major role in the mitigation of hot urban environments. This research has developed a new type of weight scale able to measure the amount of evapotranspiration from a large, full-sized tree (maximum weighing capacity 3t, measurement precision 100g), and is using the large-sized scale to carry out long-term measurements comparing the evapotranspiration of individual trees and those located in forests.
Measurements of the individual Zelkova serrata tree specimen in a temperate region of Japan during the summer season showed a maximum evapotranspiration of 44.6kg within a 12-hour daytime period. The trend of transpiration rate through the year has been shown ,and the study compares the data with the previous data were further considered for the cause of the low value. Furthermore, we measured transpiration by Lysimeter (L) and Porometer (P) in 12 hours of daytime in mid-summer.
