Variation of Runoff at Tieling Station of Liaohe River Basin and Its Influence Factors
摘要
Abstract
Based on the regression analysis, Mann-Kendall rank correlation test, wavelet analysis and Spearman correlation analysis, the time series of precipitation and runoff in the area between Fudedian and Tieling Station in Liaohe River basin from 1964 to 2004 were analyzed. Some conclusions were drawn as follows: ① the distribution of annual precipitation and annual runoff were uneven, and mainly concentrated from May to September; ② the time series of annual precipitation, annual runoff and annual runoff coefficient had downward trends, and the trends of annual runoff and annual runoff coefficient were significant; ③ the distribution of annual runoff changes greatly. According to statistics, the ratio of annual maximum to minimum even reached to 11. 9 times, and the average runoff in the first decade of 21 century was 24. 3% of that in 1960s; ④ the evolution of annual precipitation and annual runoff had obvious stages and cyclical change, and there was a cycle of about 7 years and 15 years; ⑤ the decrease of precipitation and the change of the underlying surface conditions were the key factors influencing the runoff.关键词
