The basis of the precipitation cycle (hydrological cycle) division method is the climate change of seasons currently. As the global climate changes, it becomes questionable whether the basis of this division method is still sufficient. In this paper, the precipitation series of 25 meteorological stations in Guanzhong area of Shaanxi province from 1970 to 2008 has been taken as the basic data, Total Water Quantity Balance Method is used to divide the annual precipitation cycle, and then, contrast the result with the cycle comes from the wavelet analysis. The study show that: the Total Water Quantity Balance method and wavelet analysis were the consistent on the division of precipitation annual cycle, and the best annual cycle of precipitation in Guanzhong area is changed into 11 months rather than 12 months. From the perspective of the Total Water Quantity Balance method, the annual precipitation cycle in Guanzhong area has been shortened to a certain extent. It is valuable to explore the response change of hydrological law under climate change condition.
