石羊河流域径流变化特征及其驱动因素
Characteristics and Driving Factors of Runoff Changes in the Shiyang River Basin
摘要
Abstract
In order to deeply explore the characteristics and driving factors of runoff changes in the Shiyang River basin,and provide a scien-tific basis for basin management planning and ecological environment building,this study utilized the runoff data from 1956 to 2019 and ap-plied mathematical statistics to analyze the runoff characteristics,in conjunction with meteorological data to assess the impact of climate change on runoff.The findings reveal that a)a decreasing trend in runoff volumes for the Gulang River,Huangyang River,Zamu River and Jinta River,while the runoff of Dajing River and Xiyang River remains relatively stable.b)The basin exhibits periodic changes over 2 to 10 years and 10 to 30 years.c)Apart from the Dongda River and Xida River,which lack significant abrupt change years,other rivers in the ba-sin have notable abrupt changes in runoff between 1970 and 1990.d)The precipitation variation trends in the Shiyang River Basin are not significant,while the temperature has significantly increased.e)Based on the division of change points,the runoff reduction between the baseline and the change period ranges from 13.78%to 37.43%,with human activities identified as the key factor causing runoff reduction and changes.关键词
