| 摘 要： | 土壤水分在干旱、半干旱地区生态系统中起着重要的作用。在简要总结土壤水分与植物关系、土壤水分与土壤呼吸关系、生物土壤结皮对降水再分配过程的影响、土壤水分时空动态、土壤水分监测技术五个方面研究进展的基础上,认为未来干旱、半干旱地区土壤水分研究在土壤水分平衡、土壤水分与土壤呼吸作用、土壤水分监测技术的改进等几个领域还有待于深入。

| Abstract: | The soil moisture plays an important function in ecological system in arid and semi-arid regions.The paper considered that the fields of balance of soil moisture,soil moisture and soil respiration and improvement of monitoring technique of soil moisture need to be further studied in the future based on the brief summary of research progress of the following five aspects of the relation between soil moisture and plants,relation between soil moisture and soil respiration,influence of biological soil crust to redistribution process of precipitation,temporal and spatial dynamics of soil moisture and monitoring technique of soil moisture. |
