[目的

分析近150 a来长江入海流量变化的长期趋势、阶段性、突变性以及多尺度周期变化过程,为揭示长江入海流量的长期变化特征提供理论支撑。[方法
]
基于长江汉口站长时间实测水文数据,利用现代汉口站和大通站流量一元回归模型,恢复以长江大通站为代表的1865-2014年长江入海流量序列。综合利用多种方法开展多尺度分析。[结果

近150 a来长江入海流量总体上呈下降趋势;其中自1955年以来长江入海流量处于一个显著的下降期;长江流域降水量变化是影响长江入海径流变化的重要因素。
[Objective] The long-term trend
staged
abrupt
and multi-scale periodic variations of the discharge from the Yangtze River into the sea were analyzed in the past 150 years to provide theoretical support for revealing the long-term variation characteristics of the flow of the Yangtze River into the sea.[Methods] Based on the hydrological data of the Hankou station in the Yangtze River
this paper reconstructed the runoff series of the Datong Station
Yangtze River from 1865 to 2014
by using the regression model derived from Hankou station and Datong station
and made use of a variety of methods to carry out multi-scale analysis.[Results] The discharges from Yangtze River in nearly 150 years had an average flow of 29 432 m3/s
and had a coefficient of variation of 14.72%. The trend analysis showed that the discharges from Yangtze River in the past 150 years showed a decreasing trend with rate of -23.7 m3/(s·a)(p < 0.01) per year. Although
the periodic analysis showed that the change of the series had fluctuation characteristic. Two obvious different stages were recognized and it was separated at 1955. From 1865 to 1955
it was at a rising stage; from 1955 to 2014
it was at a descending stage. Abrupt analysis showed that the series had an abrupt point in 1940s
around which the water flow changed from wet period into dry term. The multi-scale periodic analysis showed that the series were obvious non-linear and nonstationary
with 150 years and 60 years of long-term trends
and with 34 years
22 years
3 to 7 years of high frequency oscillation cycles. Among of the cycles
the most obvious was 22-year one
which can be tested at 99% confidence level.[Conclusion] In the past 150 years
the flow of Yangtze River into the sea had been in a downward trend
especially since 1955
it declined significantly. The variation of precipitation in the Yangtze River basin was an important factor that affected the runoff in the Yangtze River.
