摘      要：In the Lancang‒Mekong River basin(LMRB),agriculture,dominating the local economy,faces increasing challenges in water supply under climate *** projection of future precipitation in this basin is essential for understanding the *** this study,the Weather Research and Forecasting(WRF)model was applied to project the LMRB *** with the historical period(1986e2005),we analyzed the changes of both the projected precipitation amount and the frequency of rainless(100 mm d
1)for three periods,namely the near-term(2016e2035),mid-term(2046e2065),and long-term(2080e2099).The results indicate that the precipitation amount during the wet season(AprileOctober)is expected to increase in most areas of the basin for the three *** for the precipitation during the dry season(NovembereMarch),an increase is projected in most areas for the near-term,while an increase in the lower reach of the basin and a decrease in the upper and middle reach for the mid-term and *** precipitation reduction is expected to be greatest in Myanmar,Laos,Thailand,and Yunnan province of China for the *** frequency of precipitation in different intensities has prominent regional and temporal *** the wet season,the days of rainless and light rain are expected to decrease in the middle reach,whereas the days of rainstorm and heavy rainstorm *** feature is especially strong in southern Thailand,southern Laos and Cambodia in the near-term and in Laos and Thailand for the mid-term and *** the dry season,there are projected increasing rainless days and decreasing days of precipitation for the other intensities in the middle reach,and opposite in the rest area of the *** projected precipitation changes have potential various impact in different parts of the *** middle re
