基于目估适线法，选用皮尔逊Ⅲ型频率曲线作为水文频率分布线型，在Matlab平台上编写三个M文件，分别实现海森频率格纸的绘制、频率曲线参数x軃、Cv的求解以及水文频率曲线的绘制。通过多次的适配，找到与实测水文资料配合较好的理想曲线的参数作为设计值并估算指定的水文特征值。并以某一水文测站24年的年径流实测资料为基础，检验了方法的正确性。为水文学中相关计算以及水文频率曲线的绘制提供了一种新的实现方法。

The P-III frequency curve is selected as the hydrological frequency distribution of linear,based on visual adaptability line. Three M-files was written in Matlab platform to draw the Hazen frequency grid paper,to solve the frequency curve parameters such as x、C v ,to draw the hydrological frequency curve,respectively. With the multiple adaptation,the ideal curve that fits well with the measured hydrological data is found. So we can estimate the value of the specified hydrological characteristics by the using of the ideal curve. Annual runoff measured data of a hydrological station,24 years is used to test the correctness of the method. It provides a new implementation for hydrological calculations and the drawing of the hydrological hydrology frequency curve.
