采用半分布式水文模型HSPF,结合1978-1998年东江流域实测气象数据和5个气候模式在3种RCP气候情景(RCP8.5,RCP4.5,RCP2.6)下基准期(1960-2000年)和未来时期(2020-2070年)降水、蒸发情景模拟结果,在对东江流域径流模拟检验基础上,对2020-2070年东江流域水资源量做了深入分析。结果表明,HSPF模型能很好模拟东江流域年、月径流以及洪水期径流变化,博罗站的NASH系数均超过0.81,PBIAS低于10%,RSR低于0.45;所选取气候模式能很好的反映研究流域气象数据在年内分布情况。对未来气候和东江流域水资源量模拟结果表明:① 2020-2070年不同气候变化情景下东江流域降水及蒸发量在RCP26和RCP4.5情景下均呈上升趋势,而在RCP8.5情景下,东江流域蒸发量则呈现下降趋势;② 未来东江流域多年月均径流量呈增加趋势;③ 未来东江流域不同频率下的洪水和枯水流量均呈不同程度的增长。相对于基准期,未来时期的洪水天数呈增长趋势,洪水灾害有加剧态势。
The East River basin is the principle source of water supply for megacities in/in the vicinity of the Pearl River Delta. In this study
water resources during 2020-2070 are evaluated under different climate scenarios based on outputs of 5 GCMs. The climate scenarios are RCP8.5
RCP4.5 and RCP2.6. Besides
downscaling procedure was done based on observed data covering the period of 1960-2000. The period of 1960-2000 was taken as the base period. HSPF model was used in hydrological modeling. The results indicate that: ① The HSPF model performs well in the hydrological simulation practice with NASH coefficient of over 0.81,PBIAS and RSR less than 10% and 0.45. The scenarios can well mirror the annual distribution of meteorological variables. ② The precipitation and evaporation during 2020-2070 under the RCP2.6 and RCP4.5 scenarios increase and evaporation decrease under RCP8.5 scenario. ③ The period of 2020-2070 will witness increasing monthly streamflow and also high/low flow regimes. Besides
when compared to the base period
the period of 2020-2070 will witness increasing flooding days . Flood risk will be significantly enhancing.
