摘　　要：研究抚育间伐对林下生长及林下植被多样性的影响,可为杉木人工林植被管理基础。以抚育间伐6年后的杉木人工林和未抚育的林分为对象,通过标准地法研究林木生长和林下灌木、草本、藤本植物的种类,计算了植物多样性。结果表明:与未抚育相比,杉木平均胸径和树高分别显著增加了68.93%、27.29%;抚育后杉木林下共有灌木、草本和藤本植物种类分别为13、14、11种,分别是未抚育林分的1.2、2.0和3.7倍。抚育后林下草本植物和藤本植物的多样性指数Shannon-Weiner和均匀度指数Pielou均显著升高(P<0.05)。The effects of tending thinning on understory growth and understory vegetation diversity can be studied as the basis for vegetation management of Chinese fir plantations.Plant diversity was calculated by studying the growth of trees and the types of understory shrubs,herbs and lianas after 6 years of thinning.The results showed that compared with untended trees,the average breast diameter and tree height of Chinese fir trees increased significantly by 68.93%and 27.29%,respectively.There were 13,14 and 11 species of shrubs,herbaceous plants and vines under the tending cedar understory,which were 1.2,2.0 and 3.7 times that of untended forest stands,respectively.After tending the diversity indices of understory herbs and vines,both Shannon-Weiner and Pielou were significantly higher(P<0.05).
