摘要
介绍非参数统计方法在洪水频率分析中的应用现状及其进展,指出把地区信息和历史洪水信息纳入密度函数估计中、把水文的模糊性和灰色性纳入非参数统计模型中以及解决洪水频率曲线的外延等等,是非参数统计在洪水频率分析领域的发展方向.
By analysis of the current situation of and some advances in the application of the nonparametric statistic approach to flood frequency analysis, it is pointed out that the introduction of the regional and historical flood data into the density function estimation and grey and fuzzy attributes of hydrological statistics into the nonparametric statistic model, and further extension of the flood frequency curve are the development trend of the nonparametric statistic approach in the field of flood frequency analysis.
