中文摘要：
为剖析河北平原种植条件下土壤水分运动时空变化特征,根据典型区2010年全年气象、大田灌溉和负压计监测结果,分析土壤水分运动方式及其形成机理。结果表明：1）研究区土壤水分运动基本类型以蒸发-入渗型为主,但不同季节土壤水分运动方式差异显著,尤以夏季最为复杂;2）降水蒸发、灌溉以及植物根系吸水分别在不同阶段对土壤水分运动起主导作用;3）种植条件下,垂向上剖面动态呈现显著分带性,且灌溉前后土壤水分运动类型呈周期性变化。
英文摘要：
To analyze the time-space distribution characters of soil moisture movement under planting condition in Hebei plain,this text used the data of meteorology,irrigation and tensiometer in 2010 in a typical area,and analyzed the evolution and formation mechanism of soil moisture movement.The results showed that：（1） The basic type of soil water movement in study area was evaporation-infiltration type,but there were significant differences among different seasons.Especially,it was the most complicated in summer;（2） Rainfall,evaporation,irrigation and root-water-uptake played the leading roles for the soil moisture movement in the different stages;（3） The soil water dynamic presented marked zoning in the vertical under planting conditions.The type of soil moisture movement presented cyclical variations before and after the irrigation.
