摘要
基于汛期划分的模糊性,阐述了图论聚类在汛期划分中应用的合理性,介绍了图论聚类的思想和方法。以洪家渡水库多年平均实测洪水流量为基础,考虑汛期划分的时序性,将基本的图论聚类法进行改进,利用最大树法划分了初汛、主汛和后汛,其中洪家渡水库的主讯期被确定为6月中旬到9月下旬。
In view of the vagueness of flood season division, Clustering of Graph Theory and its rationality of the application of flood season division are introduced. Based on the multi year mean measured flood flow of Hongjiadu Reservoir, the whole flood season is divided into beginning season, main season and eventual season through finding the maximal tree. And the main season is from mid -June to late September.
