| 摘 要： | 土壤水是水资源的重要组成部分，是衔接四水转换和循环的核心。土壤水分异质性是土壤水研究的关键科学问题；绿水理念下水循环、水平衡更关注土壤水分的有效性。随着土壤水观测和识别技术的完善，可能获取多尺度土壤水时空变化信息；遥感、同位素、模拟与定位观测的结合在理解土壤水过程方面起着重要作用。认识土壤水文参数在测点尺度和生态水文单元尺度间的转换机理、研究土壤水及其驱动因子的异质性变化规律、形成土壤水异质性同化和尺度转换的方法与技术是近期热点。

| Abstract: | Soil water is a major component of water resources management. The importance of soil water re- search has been progressively highlighted because soil water is the key variable synthesizing the water balance in the action of climate, soil and vegetation. Soil water heterogeneity is one of the critical scientific issues in soil water pattern of soil water heterogeneity and its driving forces, soil water assimilation and scaling techniques will be the focus of soil water research in the near future, |
