基于Mann-Kendall法的径流丰枯变化过程划分
Division of variation process of high and low runoff based on Mann-Kendall method
摘要
Abstract
The paper presented a method to divide the variation of high and low flow by using the Mann -Kendall method. Firstly, a runoff time series were divided into several time series, and then, the U values of the series were calculated to obtain. Finally, the variation process of high and low runoff was determined according to the U -1 curve. The runoff series of Zhuqi gauge station in the Minjiang River watershed and Baishan reservoir were analyzed as example. The results showed that the annual stream flow sequence with variation process of high and low runoff was 1946 to 1996 in the Mingjiang River. The variation of high and low runoff in the Baishan reservoir was 1946 to 1966 and 1967 to 1975 respectively, and the third variation one wasn't completed up to now. The result also showed that the Mann - Kendall method was applicable in dividing the variation of high and low runoff.关键词
