摘  要:
土壤水资源是土壤层内经常参与陆地水分交换的水量,特别是根系带中能被植物利用并可恢复的水量。它表现为土壤水分不断补给与消耗的动态水量。土壤水的存储、补给、更新和平衡,对农林牧业、生态环境及水资源平衡都有极其重要的意义。因此,根据土壤水量平衡原理,提出了土壤水储量的计算方法,并以华北平原沧州地区土壤水的季节变化为例,对土层储水能力进行了计算分析,以达到有效利用土壤水分之目的。

摘  要:
Based on the soil water balance theory, this paper put forward calculational methods for the water storage of soil. Taking the seasonal change of soil water in CangZhou District of North China Plain as an example, the author analyzed the water-storing ability of soil in order to utilize the soil-water more efficiently.
