Study on the Characteristics of Runoff Changes in the Source and Main Streams of Tarim River
Based on the measured runoff data of the source and main streams of Tarim River Basin from 1957 to 2022,this study uses methods such as Mann Kendall and person correlation analysis to explore the trend and mutation characteristics of runoff changes,as well as their related relationships.The results show that the overall runoff of Tarim River source is increasing,while the runoff of the main stream is decreasing.The continuous increase in land resource development in the source area of the Tarim River has intensified water resource consumption,leading to a decrease in the amount of water discharged from the main stream of Tarim River year by year.In the scenario where the frequency of runoff in the source stream of Tarim River is less than 75%,the increase in runoff in the main stream of Tarim River is smaller than that in the source stream.On the contrary,the decrease in runoff of the main stream of Tahe River is smaller than that of the source stream.
