摘    要:根据福建省沙溪口流域雨量的时空分布,以降雨量作为聚类指标,根据前期降雨影响因子按照时间序列取16个指标,在空间上根据流域测点距离水库入口的远近分成远、中、近3个层次.利用MATLAB统计工具将近年来的23场洪水过程分成了4类,继而对待预报的样本用对应的类所率定的参数进行预报.实践证明,将"系统聚类分析"方法引入该流域的洪水预报,提高了预报精度.

关 键 词:沙溪口流域  系统聚类  洪水预报

Abstract:According to the spatial and temporal distribution of rainfall in Shaxikou catchment,rainfall is used as the cluster index and 16 of them are chosen based on the influence factor of the prophase rainfall by time series.Hierarchical clustering method in MATLAB statistic tool was used to divide the data into several types which include their potential characters,then forecasting was made with the corresponding parameter.At last,hierarchical clustering method is applied in flood forecasting to increase precisi...
