| 摘 要： | 利用山西汾河灌区1993∽2002年各站点的土壤墒情实际观测资料,对该灌区主要作物生育期农田土壤墒情的时空变化规律进行分析;阐明了农田土壤墒情的季节变化大致可分为3个阶段,即：相对稳定阶段、严重失墒阶段和蓄墒阶段;农田土壤墒情的垂直变化明显表现出表层急变层、中间活跃层和底部相对稳定层3个层次。 |

| Abstract: | Based on the observed data of soil moisture and rainfall from 1993 to 2002 in Fenhe irrigation district of Shanxi province, this paper studies the spatial-temporal variety regularity of soil moisture in cropland during the growth period of main crops. The author pointed out that the seasonal variety of soil moisture can be divided into three phases as relative steady phase, moisture-loss seriously phase, and moisture-storing phase, also, the vertical variety of soil moisture clearly emerges as three layers, as sharp-changing surface layer, active middle layer, and relative steady bottom layer. |
