The effects of aspect and elevation on Castamea henryi in Shouning, Fujian, were studied using randomized block method. Three indexes including diameter at ground, numbers of flower and mass of fruit per hectare were chosen. There were significant differences of all three indexes among different aspects and elevations. The interaction of aspect and elevation were significant on numbers of flower and mass of fruit per hectare. The order of diameter at ground, numbers of flower and mass of fruit per hectare was the same: sunny slope> half sunny slope > shady slope. Along with elevation increased, diameter at ground decreased, while numbers of flower and mass of fruit per hectare increased first and then decreased, with maximum at elevation of 700 and 600 m, respectively. The yield of C. henryi in Shouning was higher in sunny slope at 600—800 m elevation. Shady slope as well as the elevation lower than 500 m and higher than 900 m were not appropriate to plant C. henryi
