摘要：对江西分宜县山下林场１４、１６地位指数级杉木林不同间伐强度固定样地林下植被作了研究。结果表明，植物种组成、重要值、结构、盖度及生物量均随间伐强度而不同。对照与弱度间伐的盖度与生物量均小于中度与强度间伐的，前者分别为３５％～６０％与１５００～３０００ｋｇ／ｈｍ２，后者分别为７０％～８０％与５０００～７０００ｋｇ／ｈｍ２。中度和强度间伐都可以促进林下植被良好发育。
The undergrowth vegetation positively plays a role on soil fertility mainte-nance in forest plantation.The improvement of soil fertility can be achieved through the de-velopment of the undergrowth vegetation.In this paper,the study was conducted to explorethe influence of undergrowth vegetation in Chinese fir plantation by thinning.The study siteswere located at the hilly areas with 14 and 16 site-index in Shanxia Forest Farm,Fenyi Coun-ty of Jiangxi Province. The study showed that thinning intensity could influence the develop-ment of undergrowth vegetation significantly,i,e,the species composition,important value,structure,coverage and biomass of the undergrowth vegetation varied greatly by differentthinning intensities.The undergrowth vegetation coverage and biomass in the stands withoutthinning(CK)or with thinning of low intensity were 35%～60%and 1500～3000 kg/hm2respectively,which were much less than those in the stand with middle and high intensitythinning,i,e,70%～80%and 5000～ 7000 kg/hm2 respectively.It was concluded that themiddle and high intensity thinning can promote the development of undergrowth vegetationin Chinese fir plantation.
