摘　　要：在调查基础上,对深圳马峦山地区的珍稀濒危植物及石笔木、白桂木和樟树3个群落特征进行了分析,并探讨了其保护对策。结果表明:(1)该区有36种珍稀濒危植物,分别属于9科20属,其中,蕨类植物2科2属2种,裸子植物1科1属1种,被子植物6科27属33种;(2)群落多样性指数,SW在4.19～4.98之间,E'在0.76～0.86之间;(3)白桂木和樟树群落频度级规律均符合A>B>C>D<E规律,而石笔木群落频度级为A>B>C>D>E,与标准频度定律不同;(4)年轮结构分析显示,三个群落总体上都处于相对稳定状态。Based on the research, the rare and endangered plants and the community characteristics of Tutcheria spectabilis, Artocarpus hypargyreus and Cinnamomum camphora are analyzed, its protection countermeasures are discussed. The results indicated that： （1） There are 36 species of rare and endangered plants form 20 genera belonging to 9 families, Among them, ferns contains 2 family 2 genus and 2 species, gymnosperms contains 1 familyl genus and 1 species, angiosperms contains 6 families 27 genera and 33 species.（2） In the 3 communities, SW index is between 4.19 and 4.98, E＇ index is between 0.76 and 0.86; （3） The frequencies index of Artocarpus hypargyreus and Cinnamomum camphora community are A〉B〉C〉D〈E, while Tutcheria spectabilis community is A〉B〉C〉D〉E, which is different from the frequency law of Raun Kiaer; （4）The Age-ratio showed that the 3 communities are in a relatively stable state in general.
