湖南永顺杉木河林场三类楠木林群落的调查分析

Investigation and Analysis of Three Kinds of Phoebe Forest Communities in Shamuhe Forestry Centre of Yongshun in Hunan Province

湖南永顺杉木河有较成片的以利川润楠(Machilus lichuanensis)、宜昌润楠(Machilus ichangensis)、闽楠(Phoebe bournei)为优势种的3类群落。笔者通过对这3类群落的调查分析,认为这3类群落具有4大特点:群落的珍稀性,组成种类的丰富性,生态环境的脆弱性,演替的相对稳定性。建议在杉木河林场建立自然保护区,严格加以保护。

In Shamuhe forestry centre of Yongshun,there were three large communities included Machilus lichuanensis community,Machilus ichangensis community and Phoebe bournei community.Through the outdoor investigation and the indoor analysis,four important characteristics such as the rarity of the communities,the richness of the made-up species,the frangibility of the ecological environment and the relative stability of the succession were found from the three kinds of communities.The author suggested to set up natural reserve and protect the precious species in the Shamuhe forestry centre.
