气候变化与人类活动对渭河源区径流量影响的定量分析
Quantitative analysis of impact of climate change and human activities on runoffin source region of Wei River
摘要
Abstract
Climate change and human activities have significantly influenced runoffin the source region of the Wei River.To identify the dominant influencing factors and quantify their impacts on runoff,this study employed methods such as the inverse distance weighting method,hierarchical clustering,and cumulative slope change rate analysis.The relationship between precipitation and runoff,runoffvariation,and the respective contributions of climate change and human activities to runoff changes were systematically examined.The results indicated that precipitation and runoffexhibited strong intra-annual correlation but weak interannual correlation.While precipitation showed a slight increasing trend,runoffpresents an insignificant decreasing trend from 1980 to 2022.A significant runoffvariation occurred in 1993,with a reduction of 201 million m3.Climate change accounted for 31.6%of the runoffreduction,whereas human activities contributed 69.4%,making human activities the dominant factor in runoffdecline in the Wei River source region.These findings provide essential references for regional water resource planning and ecological environment management.关键词
