Abstract: A comparative study of Cunninghamia lanceolata forests with different forestation densities was conducted .At the age of 32 , the storage per hectare was highest for the stand with reserved density of 1 200 trees hm-2 , intermediate for 1 620 treeshm-2 , and lowest for 600 treeshm-2 .There was a great difference in diameter distribution , with the decrease of management density , the diameter inclined to big timber .The correlation between the output of different dimension stock and stand density was significant .According to the influence of different density management measure on the growth of stands, the mathematical models of crown width-DBH and maximum density were established .Based on studying the growth , diameter grades structure and output of C . lanceolata of different planting density control , quantitative relationship models were established .The results showed that the suitable density of big-diameter-oriented cultivation were 1 005 -1 382 treeshm-2 in site index 18 and 959 -1 319 treeshm-2 in site index 20 .[ Ch , 5 tab .11 ref .]
