Based on the runoff data of Buha River Basin and Shaliu River Basin in Qinghai Lake Basin, the annual base-flow index was obtained by using the filter smoothing minimum method. The temporal and spatial variation of precipitation and the evolution law of base flow in this basin were analyzed by TFPW-MK method, and the influencing factors of base flow were analyzed. The results show that the base-flow index of Buha River Basin first increases, then decreases and increases, reaching the maximum in May and the minimum in August; The base flow index of Shaliu River Basin fluctuates and reaches the minimum in April. The annual average runoff in the Buha River Basin and the Shaliu River Basin showed a significant increasing trend, and both the annual average base flow and base flow index showed an insignificant increasing trend; The base flow inclination rate of the Buha River Basin is twice that of the Shaliu River Basin. The base flow sequence of the Buha River Basin and the Shaliu River Basin is greatly affected by precipitation, flow, drought index and evaporation, and the Shaliu River Basin is more significantly affected by evaporation.

为揭示青海湖流域的基流演变和时空变化规律,基于青海湖布哈河流域和沙柳河流域的径流资料,利用滤波平滑最小值法计算每年的基流指数,采用TFPW-MK法分析该流域基流时空变化和基流演变规律,并分析了基流的影响因素。结果表明,布哈河流域的基流指数呈增大—减小—增大的变化,5月达到了最大值,8月达到了最小值;沙柳河流域的基流指数呈减小—增大的变化,4月达到最小值。布哈河流域和沙柳河流域的年均径流量呈显著增加趋势,年均基流量和基流指数均呈不显著增加趋势;布哈河流域基流倾向率是沙柳河流域的2倍。布哈河流域和沙柳河流域的基流序列受到降水、流量、干旱指数和蒸发的影响较大,沙柳河流域受到蒸发的影响更为显著。

为揭示青海湖流域的基流演变和时空变化规律,基于青海湖布哈河流域和沙柳河流域的径流资料,利用滤波平滑最小值法计算每年的基流指数,采用TFPW-MK法分析该流域基流时空变化和基流演变规律,并分析了基流的影响因素。结果表明,布哈河流域的基流指数呈增大—减小—增大的变化,5月达到了最大值,8月达到了最小值;沙柳河流域的基流指数呈减小—增大的变化,4月达到最小值。布哈河流域和沙柳河流域的年均径流量呈显著增加趋势,年均基流量和基流指数均呈不显著增加趋势;布哈河流域基流倾向率是沙柳河流域的2倍。布哈河流域和沙柳河流域的基流序列受到降水、流量、干旱指数和蒸发的影响较大,沙柳河流域受到蒸发的影响更为显著。

Based on the runoff data of Buha River Basin and Shaliu River Basin in Qinghai Lake Basin, the annual base-flow index was obtained by using the filter smoothing minimum method. The temporal and spatial variation of precipitation and the evolution law of base flow in this basin were analyzed by TFPW-MK method, and the influencing factors of base flow were analyzed. The results show that the base-flow index of Buha River Basin first increases, then decreases and increases, reaching the maximum in May and the minimum in August; The base flow index of Shaliu River Basin fluctuates and reaches the minimum in April. The annual average runoff in the Buha River Basin and the Shaliu River Basin showed a significant increasing trend, and both the annual average base flow and base flow index showed an insignificant increasing trend; The base flow inclination rate of the Buha River Basin is twice that of the Shaliu River Basin. The base flow sequence of the Buha River Basin and the Shaliu River Basin is greatly affected by precipitation, flow, drought index and evaporation, and the Shaliu River Basin is more significantly affected by evaporation.
