Based on the survey of 16 sample plots in the bamboo forest of Phyllostachys bambusoide f. shouzhu in Liangping county of Chongqing city, the effects of 7 site factors on diameter, the clear bold height, culm height and culm wall thickness of P. bambusoide f. shouzhu were studied. The results are as follows. (1) Three site factors as the slope position, altitude, diversity of species, had significant effects on the growth of P. bambusoide f. shouzhu. The effects of the gradient, humus thickness, soil thickness were little, but that of slope aspects was not significant. (2) The forestation site should be selected at the flat ground and gentle slope below 800 m, the sites with altitude of above 800 m and the sloppiness of steep slope and slope were not suitable for the growth of P. bambusoide f. shouzhu. (3) The upper slope was not suitable for the growth of the bamboo, the mid position and foot of hills were suitable for planting the bamboo. (4) The thin soil was not suitable for the growth of the bamboo;humus thickness should be kept at a suitable level in the bamboo forest. (5) The number of plant species in the bamboo forest should be kept at a suitable level for keeping its growth environment. (6) The south and north slope aspects were all suitable for the growth of the bamboo, but the growth of the bamboo on the south slope was better.
