Effect of Different Thinning Intensities on the Growth of Larch Forest in Eastern Liaoning Province

doi:10.13466/j.cnki.lyzygl.2016.01.012

Abstract

Abstract: Experiments were conducted in different thinning intensity conditions of larch plantation.The results showed that the thinning intensities were able to promote the growth of larch DBH 8 years ofter the thinning operations,and with increasing of thinning intensity,diameter growth and volume growth effect is more obvious,which had certain influence on the tree height,but there was not significant differences.With increasing of the thinning intensity,the growth rate of stand tree volume and single tree volume growth could be improved.Because of the decrease of the tree numbers,the initial of the larch per unit area volume was significantly lower than the control after thinning.The volume of the strong thinning treatment area(295.3m³/hm²) exceeded the control area(260.57m³/hm²)8 years after the thinning treatment,and other processing unit area in the region of accumulation amount was still lower than the control area.

Key words: larch, thinning intensity, diameter, height, volume
