Abstract: In this paper,taking Fokienia hodginsii and Schima supeaba pure forests as a control,experimental analysis is made of the mixed density and ratio of Fokienia hodginsii and Schima supeaba mixed forest. The results have shown that mixed Fokienia hodginsii and Schima supeaba plantation is a better mixed combination. Analysis from the operating density B > A > C,afforestation density of 2 500 trees per hectare is favourable to Fokienia hodginsii DBH growth; in 10-year-old mixed forest from an average tree height growth analysis,Fokienia hodginsii displays a decreasing order of A > B > C. Fokienia hodginsii average height sequence from the mixed ratio analysis is B8M1 > B2M1 > B1M1 > B1MO. It is indicated that average tree height and average DBH of Fokienia hoginsii in mixed forest are greater than those in Fokienia hodginsii pure forest.
