Abstract: Tectonic stress is one of the fundamental forces, which cause crustal motion movement. Subsurface fluid and fluid force universally exist in crust, and there is important influence on the crustal movement. In this paper, subsurface fluid, fluid force, tectonic stress and their concept and action are discussed, the similarity and difference of the fluid force and tectonic stress is analyzed: the tectonic stress is a comprehensive one, which is produced through crustal deformation, and the fluid force is a resultant one, which is produced through fluid existence and activity. Their force sources are mainly originated from the interior of the earth, their different connotation and the size. However, they all cause tectonic movement.

Key words: Tectonic stress; Tectonic movement; Subsurface fluid; Fluid force; Mutual relation
