Abstract:

In this study,two types of thinning and control(non-tending)treatments were set up in 5 year-old(young),12 year-old(middle-aged),18 year-old(near-mature)Chinese Fir plantations respectively on tending before(2013)and after thinning(2015).The results showed that tending thinning promoted the growth of DBH and individual volume,and the average DBH increment was 44.4%,25.0% and 14.3% higher than that of CK,with tending the average individual volume increment was 59.3%,31.0% and 19.9% higher than that of the control,the difference was significant(P< 0.05);As for thinning on tree height growth,the promoting effect,compared with the difference,was not significant(P>0.05);tending significantly improved the Chinese Fir young and middle aged forest health status and health level of tending plot generally higher than the control one;tending improved the forest species abundance,vegetation height and coverage and the vertical structure of vegetation plots significantly;Overall,the effects of thinning on the growth of young Chinese Fir forest,plant growth and forest health were better than those of the middle aged forest and near mature forest.The results provided reference basis for the scientific tending of Chinese Fir plantation.
