Canopy meteorological factors, including solar radiation, precipitation, wind speed, relative humidity, maximum temperature and minimum temperature and soil moisture content (SMC) within 4 m soil depth were monitored daily from 1 October 1999 to 30 September 2000 in an Eucalyptus plantation in Leizhou Peninsula, Guangdong, China. Canonical correlation analysis was employed to assess impacts of canopy meteorological factors on SMC. SMC differed significantly at different layers within 4 m soil depth, which was influenced mainly by precipitation in rainy seasons. SMC in rainy seasons increased with time due to the abundant precipitation. The coefficient of variance of SMC in rainy seasons was higher than that in dry seasons.
