In order to evaluate the impact from climate change on the evolution of drought in Nujiang River Basin,a distributed geomorphology-based hydrological model(GBHM - NJ) is established herein and its parameters are calibrated and accuracy is verified with the observed data from the relevant hydrological stations,and then the hydrological process of a long time-series (19612010) of the river basin is simulated; for which the Standardized Precipitation Index(SPI) and the Standardized Streamflow Index(SSI) are respectively adopted for the analysis made on the temporal and spatial evolution characteristics of the meteorological and hydrological drought in the river basin. The result shows that(1) GBHM - NJ model can better simulate the runoff process and the spatial characteristics of the hydrological response; (2) during the period of 19612010,the frequency,coverage and intensity of the occurrence of the meteorological drought in the river basin exhibit the increasing trends,in which the meteorological drought during 19942009 is the most serious; (3) spatially,the frequency of the yearly meteorological drought is about 28% in the river basin,while frequency of the drought is higher within the mid-stream area of the river basin and is mainly distributed near Zuogong hydrological station and Basu hydrological station with the secondary in the upstream area and the lower in the downstream area relatively; (4) after coming into the 90s in the last century and the 21 century,the hydrological drought is significantly intensified,for which the drought on yearly scale is mainly the mild,while the extreme occurs in autumn and winter on the seasonal scale. Generally,the drought within Nujiang River Basin exhibits an intensifying trend under the environment of climate change.
