Assessment on Influences by Climate Change and Human Activity on Upstream Runoff Volume of Kaidu River
摘要
Abstract
The Kaidu River is an important one in the Yanqi basin.It plays an important role in maintaining the ecological balance of water and soil in the basin.In recent years, issues on the water resources in the Kaidu River catchment has caused quite serious ecological and en-vironmental issues.Based on the hydrological and meteorological data of the catchment in 1960-2011, the runoff volume, the climate change features and trends at the upstream of the Kaidu River are analyzed by application of wavelet analysis method, cumulative anomaly method and change ratio of cumulative slope.And influences on the runoff by the climate change and human activities are assessed quantitatively as well.The study and analysis show that the annual precipitation, evaporation/dissipation and runoff generally is increasing in trend.The in-crease range of the runoff is 193 million m 3 /(10 a) with the paracycle variation of 16 a and 28 a.Furthermore, it abruptly changed around 1995.The contribution rate of the climate change to the runoff increase at the upstream of the Kaidu River is 100%.The human activities rarely disturbs the runoff.关键词
