单一水位流量关系测站的间测分析

Analysis of Error Interval Hydrometry at the Station of Single Stage-discharge Relatlon

采用水位流量关系计算机拟合模型，对全国范围内２３个水文站１３０多站年的水位流量关系进行分析综合，根据历年水位流量关系曲线之间的变化方式，提出了一种简单明了的分类方法，归纳出各种类型的水文站采用各种间测推流方案时可能产生的最大误差。

his paper adopts the fitting model of stage-discharge curve,and analyses more than 130 station-year stage-discharge curves of 23 stations all over China.According to the variable pattern between stage-discharge curves over the year,it puts forward a concise classification method, and sums up the maximum error that various hydrologic stations may produce when various kinds of interval hydrometry are adopted。
