摘要
本文通过大青杨在太平林场的密度间伐实验,得出了大青杨树高和单位面积材积的定期生长量与间伐强度的关系,初步确定了培养杨树短周期工业用材林较为理想的间伐密度,为我省东部山区营建短轮伐期工业用材林提供了一定的理论依据和实践指导.
The relationship between height increment and volume-growth per hectorAnd thinning intensity was determined by means of thinning study in Populus ussuriensis plantation with different stock densities in TaipingForest Farm.And the ideal thinning intensity was primary determined forthe industrisl timber-harvest Plantation in short cycle to the Plantations. The result would provide the siviculture of the industrialtimber-harvest plantarion with theory foundation and Practical guide of Jilin province.
