摘　　要：无实测水文资料地区产沙量的确定关系到黄土高原淤地坝工程建设项目可行性研究和水土保持方案编制的科学性和准确性。目前,采用的产沙量确定方法对项目区水文泥沙特性研究不够,基础研究普遍薄弱,确定方法粗糙,致使计算结果往往与实际发生的产沙情况存在较大差距。以处于无水文实测资料地区的某开发建设项目为例,探讨无水文实测资料地区产沙量的确定方法,提出了利用相邻流域水土保持试验站径流小区观测资料和降雨产沙模型,并估算了产沙量。旨在提高无水文实测资料地区产沙量确定方法的研究,以供无水文实测资料地区小流域淤地坝工程和开发建设项目产沙量估算,以及《地区水文手册》的修编参考。The determination of sediment yield in non-measured hydrological data area is very important to the feasibility study of silt dams in Loess Plateau and the scientificity and accuracy of soil and water conservation planning. At present, the method used to determine sediment yield is not enough for hydrologic and sediment characteristics study and the performance of method is rough, so the calculation results often have a big gap with actual sediment yield. Taking a silt dam project in non-measured hydrological data area as example, the determinate method of sediment yield are discussed, and it is proposed that the observed data of soil and water conservation experimental station in adjacent basin and the model of rainfall and sediment yield can be used to estimate sediment yield. This study can estimate the sediment yield for the construction of silt dams and other development projects in small basin without measured hydrological data, and provide reference to the revision of ＂Regional Hydrological Manual＂.
