Vertical liquid movement is an important factor to geotemperture field. The geot emperature field is controlled by conducting action without ground liquid moveme nt. If in this area fluid flow is vertical the effect of ground liquid movement must be noticed. In this paper the authors discuss two kinds of mathematical m odels in which the mechanisms of ground liquid movement are different and their infe ctio to geotemperature field is different. These mathematical models can be used to estimate the liquid flux of a fault and to calculate reservoir temperatu res
