水文分割法在各种有关文献中都有记载,并为广大水文地质工作者所熟悉及应用。究其原因是各省区的水文资料系列性较长,故数据可靠,且分割方法较易掌握。但在实际应用中,各师各法,即使在同一条河流上的分割方法,亦因人而异,导致计算结果差异甚大。注意到水文分割法在目前应用广泛,实有探讨的必要。 Hydrological segmentation is documented in a variety of related literatures and is well known and applied by the majority of hydrogeologists. The reason for this is that hydrological data in a series of provinces are long series, so the data is reliable and the segmentation method is easy to grasp. However, in practical applications, the division of methods among teachers and teachers even on the same river varies from person to person, resulting in very different results. It is noted that the hydrological segmentation method is widely used at present, so it is necessary to explore it.
