Abstract:: The water resource infiltrated by rainfall is an important part of the underground water resource, which is affected by the coefficient of rainfall infiltration. The data of underground water resource in the arid aeolian sand region of Ningxia is limited; the coefficient of rainfall infiltration only can be decided through observing and verifying. The thesis estimates the coefficient of rainfall infiltration in the Middle Area of Ningxia with the precipitation data and dynamic observed records of groundwater of Maotouliang in Yanchi County, then test it with the observed records of Changshahe watershed in Tongxin County, and conclud that the coefficient of rainfall infiltration in the Middle Area of Ningxia is 0.119～0.257, which can offer reliable reference for the further study on the evaluation work of the water resources.
