| 摘 要： | 以都江堰灵岩山楠木人工林纯林为基底,在林内选设标准地(20m×20m),研究了不同种植密度灌木层和草本层植物多样性特征.结果显示:楠木人工林林下灌木层和草本层分层现象明显,草本层植物多样性大于灌木层,水麻和小竹叶菜分别为灌木层和草本层中的优势种群;灌木层和草本层的物种丰富度随楠木人工林种植密度的增大而下降;同时,不同楠木种植密度下草本层的各指数均高于灌木层,表明草本层的生物多样性高于灌木层. |

| Abstract: | Study was conducted on the undergrowth vegetation species diversities in 4 standard plots of Phoebe zhennan plantation located in Lingyan Mountain,Sichuan province.The results showed that shrub and herb had clear layer,Debregeasia orientalis and Commelina benghalensis was the dominant population of shrub and herb layer.Study on the relationship between plantation density and undergrowth species diversities showed that density had negative effect on the species diversities of shrub and herb layer.The result of indexes calculation showed that species diversities of herb layer was higher than that of shrub one. |
