摘 要：
利用多年实测降水、土壤水、地下水资料,分析了地下水浅埋区3种水分之间的定量关系。结果表明,不同降水年型有效时段内地下水埋深与时段降水量之间呈极显著线性相关性;时段末的土壤质量含水量与时段初土壤质量含水量、时段内降水量之间呈极显著线性相关性,且这种相关性在不同降水年型、不同土层之间存在着差异;当地下水埋深在一定范围内时,土壤水分明显受地下水埋深影响,二者之间有显著的相关性。

摘 要：
Using precipitation, soil moisture and groundwater data measured in shallow groundwater farmland, the quantitative relationship of the three kinds of water was analyzed. The results showed that there were significant linear relationships between groundwater depth and the precipitation within the stage with effective rainfall (rainfall at least 30 mm per 10 days), and among soil moisture(dry soil weight percent) at the beginning and the end of the stage respectively, as well as precipitation within the stage. The differences of the linear relationships also existed in different precipitation year and different soil layers. Soil moisture was obviously affected by groundwater depth within a certain range of the groundwater depth, there was a significant relativity between them.
