The thinning intensity and seed production per unit area wereclosely interrelated;
疏伐强度与母树林单位面积产种量相关密切；
While standard degree of closing of the plantation reached 0.85, current annual increment of DBH started to decline, and the intensity of thinning should not exceed 30%.
林分标准郁闭度达0.85以上时，胸径连年生长量已下降，株数间伐强度以不超过30%为宜。
Trial result showed that different intensity of tending and thinning possesses remarkable influence to woody D. B. h.
试验结果表明：不同的抚育间伐强度对林木的胸径生长有着极显著的影响。
The LSD method was used to compare intensity, moderate, weak and the controlled area, it showed intensity thinning was more significant difference than moderate, weak and the controlled area.
用LSD法对强度、中度、弱度及对照进行比较，表明强度问伐较中、弱度及对照差异显著。
