Growth Simulation for Thinned Larix plantation

The data of thinned permanent plots in Mengjiagang Forest Farm of Heilongjiang Province was used in this paper.Based on the assumption that basal area of thinned stand converge on that of unthinned plantation of the same age,which has the same number of surviving trees on the same site,a basal area growth model for thinned plantation was proposed.The thinned stand development and dynamic thinned procedure were simulated according to the thinned technological measures.
