在地球不均匀吸积模型的基础上，根据比较行星学所获得的行星演化理论、大陆进化的历史、板块运动的特点以及高温高压实验研究结果，对地球演化历史中水的总体行为进行了分析和推论。从而对地球原始壳的特点、地球上液态水成因、地球表面缺失最初８亿年历史的原因、水的总体运移趋势等有了一些新的认识。

Based on the evolution history of Moon and other terrestrial planets, continental development process, plate movement tectonics, and solar nebular condensation petrology model that suggested by writers,a discussion about the action of water in Earth’s evolution history has been carried. We think the H₂O of primary Earth existed in phyllosilicate mineral in the upper sphere of primary Earth. During the initial melting, almost all H₂O come into the primary atmosphere, so the initial crust was anhydrous. The strong impact event drawed by affect of Moon and Earth each other led to the precipitation occured, and the initial crust was immersed in liquid water and damaged completely. In continental development process most of the water come into deep of Earth through the subductions of ancient slabs. A balance between the amount of water come into Earth’s deep by subductions of plate and that come out from Earth’s deep by various volcanic action had been reached about old Tertiary period.
