The influence of terrain on the growth of Brelschneidera sinensis was discussed by measuring the tree height and ground diameter, which provided reference for the selection of B. sinensis land. The standard site was set in different slope position and slope direction, and the standard site data was analyzed. Different slope position and slope direction had significant effects on tree height and ground diameter growth. The results showed that order of average tree height and average diameter of different slope positions was descending position> middle slope position>ascending slope position . The order of average tree height and average diameter in different slope orientations was north slope,east slope,west slope and south slope.The average height and diameter of trees on thelowerslope were2.45m and4.38cm respectively,and those on the north slope were2.69m and 4.84cm respectively,the north slope of downslope is the best choice for B. sinensis Plantation .
