洞庭湖区南县站水位流量单值化分析

Uniformization Analysis of Stage-discharge Relationship of Nanxian Hydrological Station in Dongtinghu Region

为优化测验方法，减轻测验劳动强度，简化资料整编工作，对南县水文站水位～流量单值化进行分析研究。以其近十年的实测流量资料，应用落差指数法分析确定单值化方案。经检验，除受特殊水情影响的1999和2003年单一线精度稍差外，各年份单一线精度及验算精度均能满足规范要求。

To optimize the test methods, reduce the labor intensity of test and simplify the data collection work, uniformization analysis of stage-discharge relationship were made, whose scheme was determinated according to last decadels practical test material and fall index method. In conclusion, both the single-line accuracy and test accuracy of each year can meet the requirement of the standard, except that of 1999 and 2003, which were affected by the special water regimes.
