| 摘 要： | 本文在滇黔桂三省21条剖面和82个地质点中采获了牙形刺的基础上，结合古地理和沉积学等方面的丰富资料以及其它古生物带来的大量信息，讨论了牙形刺的古生态。认为南盘江地区二迭纪牙形刺的属种组合和产出频度与沉积相的关系非常密切，并划分了三个牙形刺群落生境和一个无牙形刺的区域。为本区二迭纪沉积相的划分提供了一项新的标志。

| Abstract: | It is believed through the study of conodont samples obtained that the dependence of Permian conodonts on sediments facies is strikingly apparent in the Nanpanjiang River basin. In general，both the sediment facies and the different distributiun of conodont fauna control its occurrence frequency. The interpretation of the paleoecology of Permian conodonts in this area indicates that the conodoat animals had a benthic mode of life, at least during the reater part of their life cycle. |
