摘要:

土壤水分调控着陆表-大气相互作用过程,是土壤-植物-大气连续体水分和能量交换的重要影响因子,也是影响生态系统水文、生物和生物化学过程的关键因素,是陆地生态系统中不可或缺的组成部分。本文简要回顾和评述了土壤水分点、面尺度的监测、分析方法,系统阐述了干旱半干旱区土壤水分的国内外研究进展,并结合目前的研究进展,提出了未来干旱半干旱区土壤水分研究展望,以期促进深入理解和准确预测干旱半干旱区土壤水分变化的生态与水文效应,为制定科学合理的干旱半干旱区水资源经营管理方案奠定理论基础。

Abstract:

Soil moisture regulates the landing-surface-atmosphere interaction process, which is an important factor affecting the exchange of water and energy in the soil-plant-atmosphere continuum. Soil moisture is also a key factor affecting the hydrological, biological and biochemical processes of ecosystems and is an indispensable component of terrestrial ecosystems. This paper briefly reviews the monitoring at point and surface scale and analysis methods about soil moisture, systematically described the research progress of soil moisture in arid and semi-arid region, and put forward the prospect of soil moisture research based on the present research progress in arid and semi-arid region. All this is in order to promote in-depth understanding and accurately predict the ecological and hydrological effects of soil moisture changes in arid and semi-arid areas, and lay a theoretical foundation for the formulation of scientific and reasonable water resources management scheme in arid and semi-arid areas.

Key words: soil moisture, scales, research progress, prospect, arid and semi-arid areas
