摘　　要：在没有流量控制站但有多年清水流量偶测数据的小面积河流,利用清水流量频率计算适线、降水与清水流量关系和区域降水径流关系,对清水流量评价方法进行对比研究,以探讨清水流量偶测数据应用途径。以山西省汾河上游的东碾河流域为例阐述上述研究过程,结合实际数据条件讨论上述方法的优缺点,结合水文地质条件讨论流量偶测数据的代表性及其在水资源评价中的意义。As for many small catchment streams, there are only some occasionally surveyed results of the low flow for there is no streamflow measurement station. In this paper, a contrastive study on the methods for low flow evaluation is made by taking the Dongnianhe river catchment as an example. The Dongnianhe river catchment is located in the upriver area of the Fenhe river in Shanxi Province. The curve fitting method for probability computation, the relationship between the low flow and catchment precipitation, and the relationship between the catchment runoff and precipitation are used to carry out the low flow evaluation, and the application way of the occasionally surveyed results of the low flow is discussed. The advantages and disadvantages of the above evaluation methods are discussed under the conditions of the actual data. In view of the actual hydrogeological conditions, the representation of occasionally surveyed results of the low flow and their significance in the evaluation of water resources are discussed.
