英文摘要: In this proposal,dynamical downscaling with the high-resolution regional climate models(RIEMS-Heihe,WRF and CCLM) driven by ERA-INTERIM reanalysis dataset will be used in Heihe River Basin. Long-term simulation of multi-regional climate models will be conducted to understand the impact of major factors of uncertainty on simulated results in the River Basin. And we will develop the Bayesian uncertainty assessment theory and method based on the multi-model ensemble prediction results , to contribute in reducing the uncertainty of regional climate modeling and improving models’simulation and prediction ability in the Heihe River Basin. And the dynamical downscaling methodology for key project of Heihe River Basin integrated eco-hydrological process study over this region, where there are spare observation dataset and a lack of high spatial-temperal resolution and high quality dateset,will be developped and improved. Finally, high quality and high-resolution-temperal-spatial regionl climate datesets will be provided to the key project of Heihe River Basin integrated eco-hydrological process study over Heihe Basin, to drive the integrated model which coupled ecological, hydrological and socio-economic processes. It is science foundation for the integrated model of watershed eco-hydrology and the decision support sys
