摘要
根据田间试验实测资料分析了田间土壤水分的空间变化特征和时间动态变化,探索了监测农田水分变化时如何确定其合理的取样数目,讨论了农田尺度的土壤水分应如何监测,为节水灌溉,提高田间用水管理水平提供科学依据。
Soil moisture monitoring at field scale is discussed in this paper. The characteristics of space and time-dynamic variance of soil moisture are analyzed on the base of in situ data, and accordingly, the rational sampling number of soil mois- ture monitoring can be determined. This study is aimed at improving the level of water-saving irrigation and field water use mamagement.
