中文摘要

This study aimed at the wind field variation of a sugar apple orchard on reclaimed land from riverbed in the East Rift Valley. The experimental sugar apple orchard within 3.2 hectare area was reclaimed from the riverbed of Luye River, and located in Luye Hsiang, Taitung Hsien, Taiwan, near to southern East Rift Valley. The anemometers (2.5 and 6 m height above ground surface) were set on the observational tower within 6 m height which had been set in middle side of the experimental sugar apple orchard from November, 2007 to January, 2010. The mean height of sugar apple canopy was 2.2m and the tree age was over 5 years. The primary results had shown that, the hourly mean wind speed was close to calm state in twice a day, and it was easily to distinguish the period of daytime (7am-7pm) and night- (8pm-6am). The north strong breeze inlet the southern East Rift Valley could result the wind speed in apparent increasing tendency from a half hour to one hour, then the wind speed above canopy with 0.3 m height was over 3.8 m s-1 and the wind continually swayed the branches of sugar apple tree.
