Abstract:Trial result showed that different intensity of tending and thinning possesses remarkable influence to woody D.B.H. increment. The D.B.H among degree of strong, medium and weak was bigger than the contrast by 10.13%, 18.99% and 30.38% respectively. However, different intensity of tending and thinning hadn't remarkable influence to stands' height, plant volume and total harvest quantity, therefore, identify rational remained single plant number was good to improve overall quality of the stand.
