摘要:

以5a(幼林)、12a(中龄林)、18a(近熟林)生杉木人工林为研究对象,分别设置抚育间伐与对照(不抚育)2种处理,分别于2013年底和2015年底对样地进行调查。结果表明:抚育间伐促进了胸径和单株材积的生长,年平均胸径生长量的增加值抚育比对照幼林多44.4%、中龄林多25.0%、近熟林多14.3%,年平均单株材积生长量的增加值抚育比对照幼林多59.3%、中龄林多31.0%、近熟林多19.9%,上述差异均达到显著水平(p<0.05);抚育间伐对树高生长有促进作用,但与对照比,其差异未达显著水平(p>0.05);抚育明显改善了杉木幼、中龄林的健康状况,健康等级抚育样地普遍比对照样地高一级;抚育提高了林下植被种类的丰度、高度和盖度,抚育样地植被的垂直结构明显;总体而言,抚育间伐对杉木生长、林下植物生长和林分健康的促进作用幼林好于中龄林,好于近熟林。试验结果为杉木人工林的科学抚育提供了参考依据。

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.
