Abstract: The results of 2 intermediate cutting experiences showed that there existed significant differences in the increments between 16-year-old Chinese fir(Cunninghamia lanceolata)agglomerate afforestation plantation(3 400 ~6 800 per ha)and that planted with hole method(2 500~3 000 per ha).The stock volume of the former was 72%~70. 14%higher compared with that of the latter.The former had the characters of easy in intermediate cutting paning and implementing and beneficial in improving stand quality and stability,increasing the timber yield of intermediate cutting and economic benefits.The pattern of 2 trees in a hole performs the best and the stock volume was 57. 27%~70. 14% higher than the pattern of 1 tree per hole.The net income per hectare was 13 004~14 249 RMB Yuan higher.The agglomerate afforestation was better in the aspects of timber quality of intermediate cutting,promoting the growth of reserve trees and improving the quality and benefits of final cutting timber.
