本项目拟系统研究石炭-二叠纪腕足动物古生物地理与构造古地理的协同演化关系，探讨构造古地理对古生物地理区系形成的作用- - 即古生物地理区系形成的构造古地理机制。在石炭-二叠纪各世腕足动物古生物地理区系特征、主要演化事件及总体演化趋势研究基础上，通过与构造古地理演化事件及趋势对比分析，揭示二者之间的协同演化关系。主要为：北方大区的形成演化与潘加泛大陆形成演化（一些大陆不断北移就位于北纬中、高纬度带）的关系；潘加泛大陆的"中轴大陆"的"陆障"作用与域的形成的关系；一些生物地理区系地理范围相对的稳定性与构造古地理演化的关系；有些生物地理区从暖水区到凉水区（或相反）的性质转换、地理范围的变化与构造古地理演化的关系等。此项研究不但可以确切证明石炭-二叠纪腕足动物古生物地理与构造古地理的协同演化关系；而且有助于正确理解腕足动物古生物地理形成的机制，合理而有效地解决一些实际工作中存在的问题。

This project will study the coevolution between brachiopod palaeobiogeography and tectonopalaeogeography during Carboniferous - Permian, and discuss the role of tectonopalaeogeography in the formation of palaeobiogeographic province (Realm, Region and Province), that is the tectonopalaeogeographic mechanism of forming palaeobiogeographic province (Realm, Region and Province).Based on the study of the character, the main evolutionary events and the general evolutionary trend of brachiopod palaeobiogeographic province (Realm, Region and Province) during each epoch of Carboniferous - Permian, and through mading comparative analysis with the evolutionary events and trend of tectonopalaegeography, this study will reveal the coevolution between brachiopod palaeobiogeography and tectonopalaeogeography. These are mainly composed of the relationships between the formation and evolution of Boreal Realm and that of Pangea (some continents continuously moved northward and located in middle and high northern latitudes); the "continent barrier" effect of Pangea "middle axis continent" and the formation of palaeobiogeographic regions; the relative stability of geographical range of some palaeobiogeographic province (Realm, Region and Province) and the tectonopalaeogeographic evolution; the transformation of the palaebiogeographic nature from cool-water to warm-water (or inverse), the change of geographical range and the tectonopalaeogeographic evolution; etc. This study will not only prove the coevolution between brachiopod palaeobiogeography and tectonopalaeogeography during Carboniferous - Permian, but also rightly understand the forming mechanism of brachiopod palaeobiogeography, which is helpful to solve the problems legitimately and effectively in practical work.
