Reducing number of discharge measmements is of great importamce for the combination of sitegauging and tour gauging for hydrological data collecting and Processing, based oon the analysis of thegauging station characteristics,taking Zhuzhou Hydrological Region of Hunan Province as an example,classifiesestablished with different analysing methods for various kinds of stations, On this basis,generalizedestablished with different analysisng methods for various kinds of stations.On this basis generalizedstag-discharge relation models are established with the observed data for the stations with unsteadystage-discharge relation. The estimated results of discharge are satisfaetory.These models proposed in this paperare suitable for other similar hydrological regions.
