摘　　要： 黔南紫云猴场扁平村发育有石炭纪全球罕见的大规模典型的后生动物骨架礁,该礁体的主体部分由大型笙状群体四射珊瑚Fomitchevella建造而成,下部发育点礁层,形成了罕见的、独特的石炭纪礁体类型。对该礁体的造礁群落详细研究,尤其是对Fomitchevella造礁群落的研究后发现,造礁群落内生物结构、物理结构决定了群落的整体面貌而造礁群落的营养结构是维持这种面貌持续发展的主要因素,从而这3个方面共同作用来达到复杂的造礁生态体系的平衡。在礁体的整个发展过程中,后生动物造礁群落的存在与发展是至关重要的,它们维持了一个相对复杂的造礁生态体系的平衡发展。群落的整体面貌、生态体系都是由群落内的关键种所决定的,如果将群落内起到核心作用的物种从群落内移走,那么群落的性质,生物的组成和功能都将发生变化。 A rarely large-scale metazon framework is developed widely in Bianping Village, Houchang Town, Ziyun County, South Guizhou Pronince in the Carboniferous Period. The Bianping reef is constructed mostly by big phacelloid Fomithevella and its basement is composed of patch reefs, thus, forming a unique type of the Carboniferous Bianping reef. Detailed research on the reef-building communities, especially Fomithevella communities, shows that biologic and physical structures of the communities play decisive roles in constructing overall structure of reef-building communities, while tropic structure of the community is a main factor to maintain development of the communities. The combined effect of biologic structure, physical structure and tropic structure leads to ecosystem balance of the reef-building communities. The whole reef-building process is closely related to occurrence and development of the metazoan reef-building communities. The overall natures and ecosystem of the community are decided by the key species in the community. The character, composition and function of the communities would change correspondingly, if the key species were taken out.
