 In this paper, the authors propose a practical method for quantitative assessment of regional water conservation based on regional water balance, actual evapotranspiration from land surfaces calculated by applying the principles of the surface energy balance system, and surface runoff by SCS (Soil Conservation Service) model.  The result shows that: 1) in the water conversation area of Qilian Mountains, water-holding capacities in central and southeastern region are higher than that of in western region; and 2) water-holding capacities in central and southeastern region have been decreasing obviously, and the deterioration area was constantly formed with the Menyuan Hui Autonomous County as the center.
