    Data-Driven-Based Attribution of Runoff Changes in Tuwei River Basin in the Northern Windy-Sandy Region of Shaanxi by YU Huanghao, LI Binquan

    Published 2022-01-01
    “…The key point in analyzing the attribution of runoff changes is whether the natural runoff process of the basin can be accurately simulated.However,the application accuracy of hydrological models in arid and semi-arid regions of the Loess Plateau is generally not high.Taking the Tuwei River basin in the northern windy-sandy region of Shaanxi in the middle reach of the Yellow River as an example,this paper proposed an improved natural runoff simulation method based on the data-driven approach,so as to quantitatively analyze the effects of climate changes and human activities on runoff changes in the Tuwei River basin.The results show that the annual runoff series in the basin decreased significantly from 1961 to 2015,and there were two abrupt changes in 1979 and 1996,respectively.The annual runoff of the two periods (1980—1996 and 1997—2015) is 25.8% and 47.1% lower than that of the natural period (1961—1979),respectively.The runoff simulation accuracy of the three data-driven methods after improvement rises significantly.Specifically,the improved method proposed by Zhao Wenlin has the highest accuracy,and the Nash-Sutcliffe efficiency coefficient of annual runoff simulation in the natural period is 0.77.Climate change is the main reason for the significant decrease in the runoff between 1980 and 1996 (with a contribution of up to 80.9%).However,from 1997 to 2015,the contribution of climate change and human activities to the decrease in the runoff changed,with the influence of human activities increasing to a proportion of 58.8%.…”

    Temporal-spatial Evolution of Drought Characteristics at Different Grades in Yulin by KONG Gang, ZHANG Shanliang, WANG Lu, HUANG Shengzhi, BAI Jueying

    Published 2021-01-01
    “…Under the background of climate warming and human activities,Yulin city suffers from frequent drought,which has adverse effect on the agriculture,ecological environment and social economy in this area.Although the adverse effects of drought on the Loess Plateau have attracted the attention of many scholars,there is still a lack of grid and refined spatial and temporal assessment of drought in Yulin City.Therefore,taking Yulin City as the study area,based on the monthly precipitation and soil moisture data with a spatial resolution of 0.25°×0.25°,this paper calculates the standardized precipitation index (SPI) and the standardized soil moisture index (SSMI) on three month scales,identifies the drought characteristic parameters by the run theory,and analyzes the spatial-temporal evolution of drought characteristics at different grades.The results show that:The drought is rigorous in Yulin city.In time,a wet trend appears in spring and winter,while a dry trend in summer.In space,there is a significant dry trend in the southern of Yulin city.There are more than 6 months of long-term precipitation deficit and 12 months of long-term soil moisture deficit in Yulin City,respectively,and the month with consecutive precipitation deficit come earlier than the soil moisture deficit.Areas with high drought frequency are located in the northern,southern and eastern edges of Yulin.The conclusion is of great significance to the drought prevention,social production and ecological environment in Yulin city.…”
