谈杨树人工林间伐实验

本文通过杨树在白杨木林场的密度间伐实验，得出了杨树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。

In this paper, the density of poplar in poplar forest farm thinning experiment, obtained poplar＇ s high and volume per unit area of the relationship between periodic increment and thinning intensity, preliminarily determines the cultivation of poplar short-cycle industrial timber forest ideal thinning density, for the eastern mountain area construction in our province short rotation period industrial timber forest provides certain theory basis and practice guidance.
