| 摘 要： | 为了充分认识土壤水及其水资源特性,在淮北平原汉王水文水资源实验站对0.5～3.5 m地下水位控制条件下和秸秆、地膜、无覆盖三种条件下的土壤水分、包气带储水量、潜水蒸发、土壤蒸发、降雨入渗等要素进行了连续4年的观测,并结合水量平衡方程,对土壤水资源的要素特征进行了实验研究.结果表明：同一深度的土壤含水量大小顺序为秸秆覆盖〉地膜覆盖〉无覆盖;覆盖条件下土壤含水量变化相对稳定;土壤包气带有类似于土壤水库的作用,可调节水量可观,土壤水可作为一种重要的水资源;随土壤包气带厚度加大,潜水蒸发和降水下渗逐步减少,土壤蒸发表现突出.研究认为,充分认识土壤水资源特征,对指导土壤水资源开发利用、农业生产等有重要意义. |

| 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 four-year 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 plastic-film 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. |
