摘要:径流演变特征研究可为在变化环境下制定流域水资源规划、建立流域水文响应机制提供科学依据。以沙颍河流域代表水文站阜阳站为例,运用M 2K 检验法和小波分析法分析了1956年-2011年径流变化特征,并从气候变化及人类活动的角度分析了径流变化的主要驱动因素。结果表明:沙颍河阜阳站径流总体呈下降趋势,但下降趋势不明显,总体未达到95%显著性水平;在1966年前后存在明显的突变点;径流存在13a 、26a 两类周期变化特性,周期演变过程受人类活动影响显著。就驱动因素而言,人类活动对径流变化的贡献率在65%以上,气候变化对径流变化的影响较弱,表现为从负向到正向的趋势。

Abstract:T he study on the character istics o f runo ff ev olut ion can prov ide a scient ific basis fo r the development o f water re 2sour ces plans and establishment o f hydrolog ical r esponse mechanisms.In t his study ,the runoff evo lution cha racteristics of F uy 2ang stat ion wer e analyzed using M 2K test and wav elet analy sis based on the discharg e data o f Fuyang hydro metric station from 1956to 2011,and the main facto rs influencing the r unoff chang es w ere analy zed from the per spectiv e o f climate chang e and hu 2man activ ities.T he r esults show ed that t he r unoff o f F uyang statio n of Shaying he R iver decreased but the decr easing trend w as no t significant,no t reaching the 95%sig nificance level.A n abrupt chang e occur red ar ound 1966.T here was a 132year perio dic variatio n and a 262y ear perio dic v ariation of t he r unoff,and the per io dic evo lutio n pr ocess w as affected by human activ ities sig 2nificantly.As fo r the driv ing fact ors,the contributio n rat e of human activit ies to runoff changes was mo re than 65%.T he impact of climate change o n r unoff changes was r elativ ely weak,and tended to turn fro m neg ative to po sitiv e.
