摘 要：
为了更好地保护和利用楠木(Phoebe zhennan)种质资源,采用群落生态学方法对湖北利川楠木群落进行了调查,记录了目的物种的分布状况、资源数量、生境条件等,分析了其群落特征以及不同因子对该楠木群落的影响,揭示了楠木群落与生存环境的相关规律。结果表明:2个调查样地中,沙溪乡的楠木数量多于毛坝镇,楠木种群结构更完整,发展潜力更好;总体来说,海拔、坡位对楠木种群个体数量影响较大,对胸径和高度影响较小,坡度对其影响较大,15°的坡度是楠木分布最为理想的坡度。样地群落是以楠木为优势树种的楠木林群落,也有少量润楠、宜昌润楠等。

摘 要：
In order to better protect and develop Phoebe zhennan germplasm resources,community of Phoebe zhennan was Lichuan Area of Hubei Province was investigated with the method of community ecology.Its distribution,number of resources growing environment were recorded.The impact of environmental factors on the community were analyzed.The relationship between Phoebe zhennan community and its living environment was revealed.The results showed that the number of Phoebe zhennan was Shaxi Village was more than that was Maoba Town,it had more complete population structure and better development potency.On the whole,as for Phoebe zhennan population the quantities of the species were greatly influenced by altitude and slope positions,but it had less impact on the breast diameter and height and it was highly affected by slope positions,slope of 15 degrees was the most ideal slope of Phoebe zhennan distribution.The community was an Phoebe zhennanforest,the dominant tree species was Phoebe zhennan,with a few Machilus pingii,Machilus ichangensis,etc.as its companion trees.
