英文摘要	With the wide application of drip irrigation under mulch in semi-arid agricultural region in China, it not only improves agricultural water efficiency, but also affects formation of groundwater and the mechanism of water infiltration to a certain extent. This paper takes the typical semi-arid agricultural region in China as the research object. The movement of soil water under the three types of underlying surface was simulated by the Hydrus-2D model for the quantitative analysis of groundwater recharge. The influence of drip irrigation under mulch on groundwater infiltration depth and cumulative infiltration amount under different level years was simulated. Taking normal flow year as an example, the simulated results showed that the maximum infiltration depth of drip irrigation under mulch reached 250 cm, which was greater than that of border irrigation (138 cm) and bare area (158 cm). The cumulative infiltration amount of drip irrigation under mulch at 80 cm, 120, 140 and 200 cm was respectively 1,484.8 m(3)/hm(2), 686.3 m(3)/hm(2), 554.1 m(3)/hm(2) and 238.1 m(3)/hm(2), which were greater than that of border irrigation and bare land at the same depth. The results proved that drip irrigation under mulch could increase the infiltration depth and cumulative infiltration amount, which was beneficial to groundwater recharge in semi-arid agricultural region of China.
