| 摘 要： | 腕足动物的分布主要受温度—纬度控制,凉水型分子的地理分布、迁移与古气候的变化关系十分密切,向赤道方向的进退则代表了古气候的冷暖变化。通过兴蒙造山带中二叠世哲斯几个凉水型腕足动物属的地理分布特征分析,Yakovlevia具两极分布的特征,为典型凉水分子。

| Abstract: | The distributions of brachiopod are controlled by temperature and latitude. The geography distribution and migration of the cold-water-type brachiopod are closely related with the change of paleoclimate, which go forward or backward to equator indicate the paleoclimate changing cold or warm. Studied on the genus geographical distribution of some cold-water-type brachiopod in the Zhesi Stage brachiopod fauna of Mongol-Hinggan Orogenic Belt, some cold-water-type members, such as Yakovlevia, appear bipolar distribution, which shows the feature of bipolar distribution. |
