Abstract: Different measures for the progressive replacement of Chinese fir forest with Aleurites montana was studied. The results showed that in the 15-year-old Chinese fir plantation, the L622 treatment, interplanting Aleurites montana by staggering 2.0 m on both sides of 2.0 m away from the contour chopping line at interval of 6.0 m, and the L725 treatment, interplanting Aleurites montana by staggering 2.5 m on both sides of 2.5 m away from the contour chopping line at interval of 7.0 m, both had efficient managing effects and high afforestation preservation rate, and the Aleurites montan grew well with high yield of fruit per plant.
