摘要
风水林是区域乡土植物的重要栖息地和种源地,也是一些珍稀濒危植物的生长地。以广州市增城钟岭村的风水林为对象,研究其群落结构和生境特征,并分析群落内珍稀濒危植物格木和土沉香的种群特征。在800 m^2样地内有维管束植物31种,隶属于21科28属,以热带分布科和属占优势。林内优势种有5种。群落可分为乔木层、灌木层和草本层3个层次,缺少层间植物。生活型以中、小高位芽为主。该风水林内有珍稀濒危植物格木(Erythrophleum fordii)和土沉香(Aquilaria sinensis),格木以大个体为主,缺乏幼苗,自然更新不良,而仅有1株土沉香幼苗。为了保护区域内的乡土种种源,建议将广州市内有珍稀濒危植物生长的风水林设为自然保护小区并进行严格管理。
Geomantic forest is one special type of vegetations and seed source of regional native plant.Some rare and endangered plants often grow in the geomantic forest.This paper studied the community structure and habitat characteristics of geomantic forest at Zhongling Village,Zengcheng City,Guangzhou,South China.The paper also reported the population characteristics of two rare and endangered plants(Erythrophleum fordii Oliv,Aquilaria sinensis(Lour.)Gilg)in the community.There are 31 species of vascular plants in the 800 m^2 plot,belonging to 21 families and 28 genera.The community is dominated by tropical families and genera.There are five species of dominant species in the forest.The community stratification can be divided into tree layer,shrub layer and grass layer.It is lack of vines and epiphyte.The plants with medium and small high buds dominate the community.The population structure of Erythrophleum fordii and Aquilaria sinensis is unreasonable.Our findings show that the geomantic forest does not effectively protect the rare and endangered plants in the community.We recommend that the geomantic forests with rare and endangered plants in Guangzhou should be set up as small natural reserves with strict management.
