| 摘 要： | 对张家界国家森林公园内杉木过熟林林下草本植被的分布情况开展初步调查研究.结果表明,杉木过熟林林下草本植物种类繁多,数量庞大；随着杉木林老化程度的加重,林下的阴生草本植物在减少,逐步出现阳生草本植物并在数量上有增加的趋势；下坡位的环境更适于草木植物生长.对林下草本植物的重要值分析结果,半边旗表现出最高的重要值,处于优势地位.

| Abstract: | Distribution of understory herbaceous vegetation in over mature China fir afforestation in Zhangjiajie National Forest Park has been analyzed, The results show that the variety and the number of understoly herbaceous species are rich, with the severity of fir aging, understory herbaceous species in shade are reducing, but sunny side is in an increasing trend; the downhill environment is more suitable for vegetation and plant growth. Analysis results of forest herbaceous important value index show that Pteris semipinnata has the highest important value in a dominant position. |
