摘要
以白蕉站年最低潮位的统计分析为例,对极值Ⅰ型和对数Γ分布线型与经验频率点据拟合结果进行了比较。作为一种尝试,采用对数Γ分布线型拟合白蕉站年最低潮位资料系列进行频率特性分析,取得了较为合理的分析研究成果。验证了白蕉站年最低潮位频率分布线型服从对数Γ分布线型。
Taking the statistical analysis of yearly minimum tidal level in Baijiao Hydrological Station for example, this paper compared logarithm gamma distribution and Extreme- value Type Ⅰ distribution with the result based on optimum curvefitting for estimating the characteristics of the empirical frequency. In this paper, attempt was made, the distribution of logarithm gamma pattern is used to analyze the frequency characteristics of yearly minimum tidal level data series in Baijiao Hydrological Station, and the result turned out to be valuable. The distribution of logarithm gamma pattem of yearly minimum tidal level in Baijiao Hydrological Station has been proved.
