黔南紫云晚石炭世微生物岩与珊瑚格架礁的共生为我们研究晚石炭世微生物岩与珊瑚礁的协同演化机制以及与生物灭绝事件的耦合关系提供了重要的研究对象。开展微生物岩与珊瑚格架礁的研究能够更好的揭露晚石炭世黔南地区在特殊的地史环境背景下的成礁机制和演化线索，构建滇黔桂海盆石炭纪生物礁演化模型。通过本项目的实施，将全面系统的认识黔南紫云地区微生物岩与珊瑚格架礁的形态、规模、展布特征及相互关系，并准确描述微生物群落和造礁群落面貌，查明微生物岩与珊瑚格架礁的相互作用；通过开展古生态学的研究，查明在礁体发育建造过程中微生物与后生造礁生物之间的生态关系及生态功能，构建黔南紫云晚石炭世生物礁的生态系统的群落结构和能量流动，探索它们维持发展的动力来源；利用地球化学测试分析手段评估微生物岩发育的影响因素和控制因子，揭示生物碳酸盐岩与生物灭绝事件之间的耦合关系。

The symbiosis of microbialite and coral-framework reef in Ziyun country of Southern Guizhou Province provides an opportunity to study the co-evolution mechanism between microbialite and coral-framework reef. The research about the reefs could be to make know the coupling relationship between microbialite and biotic extinction event. And the research on microbialite and coral-framework will expose the reef-building mechanism and evolutionary clues in the special geologic environment of Southern Guizhou, then bulid the evolution model of the Carboniferous reef in Yunnan-Guizhou-Guangxi basin. This study can help us to know the shapes, sizes, distribution characteristics and relationships between microbialite and coral-framework reef, and to reconstruct microbial community and reef community accurately, finally to reveal the interaction between microbialite and coral-framework reef. According to paleoecology, we can find out the ecological relationships and ecological functions between microbialite and coral-framework reef during reef development phase, then build the ecosystem of Late Carboniferous reef with community structure and energy flow in Ziyun in Southern Guizhou, so as to explore the power source that maintaining the development of reefs. By Geochemical analysis, the influence factors on the microbialite will be evaluated. Thus, the coupling relationship between microbialite and biotic extinction event will be established.
