摘要
在阐述土壤水资源的概念及特点的基础上,讨论了土壤水资源的价值、资源结构和补给特征;分析了土壤水资源量的计算方法;探讨了土壤水资源数量和质量的评价标准;提出了土壤水资源高效利用的措施。开展土壤水资源理论和开发利用方法上的研究,掌握不同地区土壤水分变化规律,是建立节水型农业的基础,也是有效缓解我国水资源严重不足、实现粮食安全的有力保障。
Research on soil resources is an important part in analyzing agricultural water resources. Soil water resources influence the formation of surface water and groundwater directly, and also determine the quality of natural ecological environment in the region. Based on the discussion on the concept and characteristics of soil water resources, the values, components, replenishment and calculation methods of soil water resources were analyzed, and the evaluation criterions about the quality and quantity of soil water resources were discussed. Measures for the efficient utilization of soil water resources were put forward. The research on theories, utilization methods of soil water resources, and variation in different areas provides a basis for the establishment of water-saving agriculture and also a strong guarantee to resolve water resources scarcity problem and to realize foodstuff safety.
