摘要

利用Mann—Kendall秩次相关趋势检验和累计平均滤波器及Mann—Kendall突变点检验

对嘉陵江流域北碚、亭子口、武都和武胜4个水文站1960—2009年的年径流数据分析得出

4个水文站年径流量均存在显著的减少趋势

且均于1991年前后存在突变点。对流域4个水文站的基准期与措施期建立降雨—径流双累积曲线方程

分析计算得出20世纪90年代人类活动和降雨对径流减少的影响程度基本相当

只有武都站人类活动影响程度稍高。

Abstract

The Changes of annual runoff at Beibei

Tingzikou

Wudu and Wusheng hydrological stations inthe Jialing River basin from 1960to 2009are investigated using Mann-Kendall trends test

Mann-Kendallabrupt changing test and cumulative average filter method.Results indicate that runoff at all the stationshave a jumping point in 1991.Double cumulative curve analysis between precipitation and runoff suggeststhat precipitation and human activities exert almost the same influence to the runoff reduction during the1990s

except the Wudu Station where the influence by human activities takes a relative higher proportion.
