Abstract：In order to understand soil water and characteristics of its resources, some parameters including soil moisture, moisture storage capacities, evaporation, infiltration have been observed for fouryear in Hanwang Experimental Station of Hydrology and Water Resources located in Huaibei Plain under 0.5-3.5 m groundwater levels and three mulch conditions. And a water balance was also used. The results showed that in the same layer the soil moisture content was the highest with straw mulch, the lowest without mulch, was in between with plasticfilm mulch; the changes in soil moisture were relatively stable under mulch conditions; soil unsaturated zone, which is similar to a reservoir, plays an important role in regulation and storage of soil water. Thus, soil water can be considered as an important water resource. With increasing thickness of soil unsaturated zone soil evaporation was pronounced, but phreatic evaporation and infiltration were gradually reduced. The present result has significance in exploitation and utilization of soil water resource and agricultural production.
