大通水文站位于长江下游，在其流量、水位资料整编工作中，一直采用连时序法，因而工作强度较大、成本较高，且极易出现人为误差。为解决以上问题，提出采用落差指数法进行数据处理，同时在确定单值化后流量与水位之间的关系时，多项式函数和指数函数是常用的两种函数关系。为研究落差指数法用于大通水文站资料整编中的可行性以及采用不同函数关系对处理结果的影响，编写了相应的Matlab程序，并以大通水文站2011年和2012年实测的水位和流量数据为例，获得该段时期内的对应参数。结果表明：(1)落差指数法在大通水文站的资料整编中具有较好的适用性；(2)该水文站单值化后的流量与水位间更符合多项式函数。

The method adopted to study on the water level-discharge relationship at Datong station, which locates at downstream of Yangtze River, has some disadvantages, such as much costs, high working strength and more artificial error. The single valued processing is advised to solve such problems. Two functions, polynomial one and exponential one, are used to study on the relationship between singe valued discharge and water level. A self-compiling program based on Matlab is used to study on the water level-discharge relationship during 2011-2012. And the result from different functions show that (1) fall index method is advised to be widely used at Datong station;(2) polynomial function is better than exponential one to study on the water level-discharge relationship.
