| 摘 要： | 为了论证暴雨选样间的频率转换的合理性和可行性,以及合理的频率转换模型,对福建省9个市49座城镇雨量观测站实测的资料进行分析计算,以离差绝对值和、离差平方和以及Nash-Sutcliffe作为误差评定标准,分别计算各自的暴雨设计值的离差绝对值和、离差平方和和NSE值。最后分别计算49个站点不同历时离差绝对值和平均值、离差平方和平均值以及NSE值平均值。计算结果表明:P-Ⅲ型分布是短历时暴雨最佳拟合线型,配合模型2,可以作为福建省城市暴雨频率转换关系式。

| Abstract: | To study rationality and possibilities of the conversion frequency in storm sampling and reasonable frequency conversion model,take 49 towns of 9 cities,which are located in Fujian province,as a study project.According to sum of absolute value of deviations and sum of squares of deviations and NSE of the Nash-Sutcliffe,the error standard of criteria was used to calculate in different short duration.Then,we can get some mean value,such as sum of absolute value of deviations and sum of squares of deviations and NSE for 49 towns of Fujian' 9 cities mentioned above.Results showed that: P-Ⅲ is the best fitting line-type,and model 2,which fits p-Ⅲ,can be the frequency conversion model of short duration storm in the province of Fujian and can be applied to engineering design. |
