广花地区早石炭世石磴子期生态地层特征

The Ecostratigraphic Character of Early Carboniferous Shidengzi Age in Guangzhou-Huadu Area

基本查明了广花地区下石炭统石磴子组中的古生物化石及其组合面貌、生存期的生活方式、死亡后的埋藏特点以及化石与围岩的相互关系．分析了石磴子期古生物的属种及生态在空间上的变化、在时间上由老到新的连续性和演化更替以及古生物生存发展的机理．对于恢复这一地区石磴子期的古环境，合理划分地层以及掌握碳酸盐岩的形成规律。

The various fossils of early Carboniferous Shidengzi formation in Guangzhou Huadu area may reconstruct the assemblage character, the living manner of the paleobiocoense and the buried characters of the dead bodies. They may also infer the evolution and displacement of the paleobiologic genus and species in time and space and the mechanism of their living and developing within the geologic time. The ecostratigraphic characters are significant for recovering the paleoenvironment, subdivising the strata and realizing the law of formation and distribution of the carbonate rocks.
