摘要
Abstract
The use of Moving Cut Data-Approximate Entropy made variation analysis for runoff series of Zhangjiashan Station on the Weihe River in the period of 1960—2001. The results show that the runoff series of Zhangjiashan Station have undergone abstract variation in the year of 1967,1971,1983 and 1996. Comparing with both Moving Approximate Entropy and Mann-Kendall methods,the result of Moving Cut Data-Approximate Entropy,which is depended less on moving window and which has higher detection accuracy,is stable,convenient and accuracy.关键词
