摘　　要：长期以来,由于我国墒情监测工作相对薄弱,有关土壤水分常数研究起步较晚,土壤水分常数的测定方法不统一、不规范,测定结果也有一定差别。从生产实际出发,通过多年工作经验和有关技术规范制定成果基础上,系统地阐述了土壤水分常数有关测定方法,为进一步规范土壤水分常数测定流程和技术要求提供借鉴和参考作用,为研究土壤物理特性、墒情实验和墒情监测与评价等提供技术支撑,为各级政府部门指挥抗旱减灾提供可靠决策依据。For a long time,due to the relatively weak monitoring of soil moisture and the late start of soil moisture constant study, there is no unified standard for constant soil moisture measurement methods, and there are some differences in the measurement results. This paper systemtically expounded the soil moisture constant determination method, providing the the reference for standardizing the determination process of soil moisture constants, providing the technical support for soil physical property studying, soil moisture monitoring and evaluation, and providing the reliable decision basis to the government departments for drought relief and disaster reducing.
