一、研究造林密度的意义用材林的造林密度,对单位面积的木材产量和质量有重要影响,还影响造林成本,造林后的间伐利用和人工林的生长发育,关系到整个营林工作的多快好省,还是少慢差费。可见造林密度是造林工作中一个重要的问题。如果造林密度过大,势必增加造林抚育费用,同时也不利于林木生长,减少林分的木材产量,降低经济收益。提前间伐,间 I. The Significance of Studying Afforestation Density The afforestation density of timber stands has a significant impact on the yield and quality of timber per unit area. It also affects the cost of afforestation, the use of thinning after afforestation and the growth and development of plantations, which affects the whole afforestation work much faster A good province, or less difference fee. Can be seen afforestation density afforestation an important issue. If the afforestation density is too large, afforestation and rearing costs will inevitably increase, but also not conducive to the growth of trees, reduce the wood yield of the stands, reduce economic benefits. Thinning in advance, between
