• Abstract: The appearance of mantle plume hypothesis is a significant milestone in the history of geodynamics research, which has been an important supplement to the theory of plate tectonics. However, with the development of earth science, debates on whether the mantle plume theory is credible has been more intense. Based on the achievements of mantle plume research in geochemistry, geophysics and geodynamic fields, this study summarizes 4 alternative geological models to substitute the present mantle plume model. Meanwhile, the couplings between mantle plume and hydrothermal activities in mid-ocean ridges and large low shear wave velocity provinces provide a new way to research seafloor hydrothermal activity. 地幔柱学说的提出对板块构造理论做了重要补充，是地球动力学研究 历程中的重大里程碑。随着地球科学的不断发展，地幔柱学说正面临着诸多质 疑与挑战。本文在总结地幔柱学说目前在地球化学、地球物理、地球动力学等 研究进展的基础上，总结了 4 个可以替代地幔柱进行解释的地质模型。同时本 文对全球热液喷口与大型剪切波低速省的分布特征进行研究，结果指示洋中脊 的海底热液活动区与地幔柱作用区存在明显耦合关系，这也为海底热液活动的 研究提供了新思路。
