The Analysis Effect of Thinning in Natural Shaw

The monumented sample was set in the Caohekou town Benxi city Liaoning province and looking into the growth in the different thinning intensity.After analysis,the shaw in the mid-thinning intensity grows well and its rate of stand volume was largest,then it was,and high-thinning.the plant diversity of herbage and wood in high-thinning was the largest,then it was contrast,mid-thinning and ebb-thinning.For improving effect of physicochemi-property,ebb-thinning was the best,and then it was contrast,mid-thinning and high-thinning.
