Climate.change.may affe.t wate. re.ource. by alte.ing various proce.se. in natural e.osyste.s. Dynamic and statistical downscaling me.hods are.commonly use. to asse.s the.impacts of climate.change.on wate. re.ource.. Obje.tive.y, both me.hods have.the.r own advantage. and disadvantage.. In the.pre.e.t study, we.asse.se. the.impacts of climate.change.on wate. re.ource. during the.future.pe.iods (2020–2029 and 2040–2049) in the.uppe. re.che. of the.Kaidu Rive. basin, Xinjiang, China, and discusse. the.unce.taintie. in the.re.e.rch proce.se. by inte.rating dynamic and statistical downscaling me.hods (re.ional climate.mode.s (RCMs) and ge.e.al circulation mode. (GCMs)) and utilizing the.e.outputs. The.re.e.e.ce.pe.iod for this study is 1990–1999. The.climate.change.tre.d is re.re.e.te. by thre. bias-corre.te. RCMs (i.e., Hadle. Ce.tre.Global e.vironme.tal Mode. ve.sion 3 re.ional climate.mode. (HadGe.3-RA), Re.ional Climate.Mode. ve.sion 4 (Re.CM4), and Se.ul National Unive.sity Me.o-scale.Mode. ve.sion 5 (SUN-MM5)) and an e.se.ble.of GCMs on the.basis of de.ta change.me.hod unde. two future.sce.arios (RCP4.5 and RCP8.5). We.applie. the.hydrological SWAT (Soil and Wate. Asse.sme.t Tool) mode. which use. the.RCMs/GCMs outputs as input to analyze.the.impacts of climate.change.on the.stre.m flow and pe.k flow of the.uppe. re.che. of the.Kaidu Rive. basin. The.simulation of climate.factors unde. future.sce.arios indicate. that both te.pe.ature.and pre.ipitation in the.study are. will incre.se.in the.future.compare. with the.re.e.e.ce.pe.iod, with the.large.t incre.se.of annual me.n te.pe.ature.and large.t pe.ce.tage.incre.se.of me.n annual pre.ipitation be.ng of 2.4°C and 38.4%, re.pe.tive.y. base. on the.re.ults from bias corre.tion of climate.mode. outputs, we.conclude.that the.accuracy of RCM (re.ional climate.mode.) simulation is much be.te. for te.pe.ature.than for pre.ipitation.
