中文摘要: 寒武纪生物大爆发之后,随着后生动物与微生物及其与生活环境之间的相互影响,很多重要的古生态特征也随之改变。这些古生态变化包括后生动物掠食行为的增加、动物矿化作用的扩大,以及底内动物生活习性和生态系统的复杂化。在后生动物扰动构造多样化发展的同时,微生物成因构造仍在世界各地的寒武纪地层中大量发育,为显生宙最大的一次蓝细菌钙化作用事件。分析豫西寒武纪各类微生物成因构造与后生动物扰动构造的耦合关系,查明寒武纪微生物与后生动物及其与环境条件的相互关联,为研究寒武纪至早奥陶世这个承前启后的特殊时期微生物、后生动物与环境的协同演化提供依据, 为揭示不同生态系统、不同营养水平上的生物(微生物与后生动物)之间以及它们与地球在不同尺度上的相互作用以及推进古遗迹学和地球生物学的发展具有重要的科学意义和应用前景。

英文摘要: A host of significant palaeoecological changes took place after theCambrian Explosion as metazoans began interacting with microbes and their environments. The changes include the increase of metazoan predation, mineralization and the complexity of infauna behavior and ecosystem. As the diversified development of metazoan disturbed structures, the microbiogenic structures widely occur in world Cambrian strata and become the biggest cyanobacteria calcifed event in Phanerozoic Eon. Ananlysis of coupling relationship between microbiogenic structures and metazoan disturbed structures and their interactions with environments from Cambrian of western Henan can help to understand the coevolution of microbes, metazoans and their environments at the special transition period of Cambrian-Early Odovician. It also has the important scientific significance and application perspective for revealing the interactions between organisms on different ecosystems and different nutritional levels and the interactions between organisms and the earth on different scales and the development of palaeoichnology and geobiology.
