Flow similarity analysis method and device

The invention relates to a flow similarity analysis method and device and provides a method for better analyzing hydrological process similarity. The method comprises steps as follows: the reversing times of a first flow hydrograph are determined; fractal dimensions of the first flow hydrograph are calculated; the similarity distance between the first flow hydrograph and a second flow hydrograph is determined according to the reversing times and the fractal dimensions, wherein the similarity distance is used for indicating similarity between the first flow hydrograph and the second flow hydrograph. 本发明是关于种流量相似性分析方法及装置，用于提供种较好的分析水文过程相似性的方式。该方法包括：确定第流量过程线的反转次数；计算所述第流量过程线的分形维数；根据所述反转次数与所述分形维数，确定所述第流量过程线与第二流量过程线之间的相似距离，其中，所述相似距离用于指示所述第流量过程线与所述第二流量过程线之间的相似性。
