| 摘 要： | 通过晚石炭世早期腕足动物化石资料分析研究,发现该期腕足动物分布主要受温度控制,温度在控制该期全球腕足动物大区一级分布十分明显.控制腕足动物地理分区的次要因素是板块构造.另外,在腕足动物迁移过程中,洋流的携带作用,海侵与海退等因素对腕足动物的分布都有一定影响.某些腕足动物具有快速散布的特点.

| Abstract: | Study and analysis of brachipod fossils reveal that brachipod distribution was mainly controled by tempreture during the early period of late Carboniferous. The first class realm is clearly tempreture controled. Next to tempreture is plate tectonics. In addition is oceanic flow, transgression and regression which are the factors to influence the realm distribution. |
