黄河上游径流统计特征及演变规律分析
Analysis of Statistical Characteristics and Evolution Law of Runoff in the Upper Yellow River
摘要
Abstract
Based on the runoff process series of 1956-2011 of Tangnaihai Station in the Upper Yellow River, the annual distribution and inter⁃annual varying characteristics of the historical runoff process was analyzed and the trend and periodicity of the runoff process series were discussed by applying the linear trend estimation and maximum entropy spectral analysis method in this paper. The results show that a) the annual distribution of runoff process in the upper Yellow River varies obviously and the runoff in summer flood period ( from July to October) accounts for 60%;b) the amount of wet and special rainy year accounts for 48.21% among the research periods, the ratio for the maximum and the minimum annual runoff is 3. 08 and the runoff process presents a weak decreasing trend, which is useful for the comprehensively development of water resources in the upper Yellow River;c) the runoff process in the Upper Yellow River has an obvious cycle periods of 28 a, 8 a and 5 a.关键词
