Based on improvement of a distributed hydrology-soil-vegetation model (DHSVM for short) and its application to North China,a nested regional climatic-hydrologic model system is developed by connecting DHSVM with RegCM2/*** simulated climate scenarios,including control and 2×CO_2 outputs,are downscaled to 8 stations in Luanhe River and Sanggan River Basins to drive the hydrology *** to simulation results,under double CO_2 scenarios,annual mean temperature and evapotranspiration will increase 2.8C and 29 mm,respectively; precipitation also increase but with different value for each basin,6 mm for Luanhe River Basin while 46 mm for Sanggan River Basin;runoff change for the two basins is different too,27 mm decrease for Luanhe River Basin while 26 mm increase for Sanggan River *** a result,the runoff in future for Luanhe River Basin and Sanggan River Basin will be 74 mm and 71 mm, respectively,which is approximately a quarter of annual mean runoff(284 mm)of the whole *** streamflow for the two basins will decrease about 2.5×10~8m^*** these indicate that the warm and dry trend will continue in the two river basins under double CO_2 *** nested model system,with both climatic and hydrologic prediction ability,could also be applied to other basins in China by parameter adjustment.

作者： Marcin Rajner Tomasz Liwosz Warsaw University of Technology Department of Geodesy and Geodetic Astronomy

In this study we compared weekly GNSS position time series with modelled values of crustal deformations on the basis of Gravity Recovery and Climate Experiment(GRACE) *** Global Navigation Satellite Systems(GNSS) time series were taken from homogeneously reprocessed global network solutions within the International GNSS Service(IGS) Reprocessing 1 project and from regional solutions performed by Warsaw University of Technology(WUT) European Permanent Network(EPN) Local Analysis Center(LAC) within the EPN reprocessing *** GNSS sites from the territory of Poland with observation timespans between 2.5 and 13 years were selected for this *** Total Water Equivalent(TWE) estimation from GRACE data was used to compute deformations using the Green's function *** frequency components were removed from GRACE data to avoid aliasing *** GRACE observes mainly the mass transport in continental storage of water,we also compared GRACE deformations and the GNSS position time series,with the deformations computed on the basis of a hydrosphere *** used the output of Water GAP hydrology model(WGHM) to compute deformations in the same manner as for the GRACE *** WGHM gave slightly larger amplitudes than GNSS and *** atmospheric non-tidal loading effect was removed from GNSS position time series before comparing them with modelled *** results confirmed that the major part of observed seasonal variations for GNSS vertical components can be attributed to the hydrosphere *** results for these components agree very well both in the amplitude and *** decrease in standard deviation of the residual GNSS position time series for vertical components corrected for the hydrosphere loading reached maximally 36%and occurred for all but one stations for both global and regional *** horizontal components the amplitudes are about three times smaller than for vertical components therefore the comparison is muc
