Study on the Chimonanthus nitens Community in Daguping Forest Farm of Shuangpai County,Hunan Province

通过野外调查样地资料,分析了湖南双牌县打鼓坪林场野生亮叶腊梅(Chimonanthus nitens)群落的种类组成、外貌特征、群落结构等基本生态学特征。结果表明:该群落种类组成丰富;群落结构完整复杂,分为乔木层、灌木层、草本层、地被层和藤本植物层。该群落是在中亚热带温暖湿润季风气候、低山地区沟谷地带、疏松肥沃土壤环境下发育的一种单优林下灌木群落类型,耐荫湿。亮叶腊梅灌丛萌芽力强,生活力较强,群落稳定。该群落科研与开发应用价值高,应对其进行严格保护。

The field sample survey was carried out to analyze the species composition, appearance features, community structure of wild Chimonanthus nitens community in Daguping forest farm of Shuangpai county, Hunan province. Results indicate that, this community abounds in species composition, community structure is complete and complex which is subdivided into arbor layer, shrub layer, herbage layer, ground layer and liana layer. This is a single predominance shrub community type in forest, which is developed in special seasonal climate of warm and wet, valley landorm in low mountain area, loose and fertile soil.
