      abstract = {The low degree of development and utilization as well as  the contradiction between supply and demand of water  resources in Huangshui River basin are the main restricting  factors of the local agricultural development. The study on  the simulation of irrigation water loss based on the VSMB  model has very important significance to strengthening  regional water management and improving water resource  utilization efficiency. Five groundwater wells were set up  to carry out the farmland irrigation water infiltration and  the experimental study on groundwater dynamic effect. Two  soil moisture monitoring sites were set up in two typical  plots of Daxia and Guanting irrigation area at the same  time and TDR300 was used to monitor four kinds of deep soil  moisture (10 cm, 30 cm, 50 cm and 70 cm). On this basis,  the VSMB model was used to study the irrigation water loss  in the irrigation area of Yellow River valley of Qinghai  Province, including soil moisture content, the actual  evapotranspiration, infiltration, runoff, groundwater  buried depth and so on. The results showed that the water  consumption caused by soil evaporation and crop  transpiration accounted for 46.4% and 24.1% of the total  precipitation plus irrigation, respectively, and the  leakage accounted for 30.3% and 60.6% of the total  precipitation plus irrigation, respectively, from March 1,  2013 to April 30, and from August 1 to September 30. The  actual evaporation of the GT-TR1 and GT-TR2 sites in the  whole year of 2013 was 632.6 mm and 646.9 mm, respectively,  and the leakage accounted for 2.6% and 1.2% of the total  precipitation plus irrigation, respectively. RMSE of the  simulation results of the groundwater depth in Daxia  irrigation area during the two periods was 92.3 mm and 27.7  mm, respectively. And RMSE of the simulation results of the  water content of soil profile in the two monitoring sites  of Guanting irrigation area was 2.04% and 5.81%,  respectively, indicating that the simulation results were  reliable.},
