Runoff variation is an important indicator reflecting the regional climate and underlying surface changes in the typical plateau region, Yarlung Zangbo River basin. Facing the global warming, there is still a lack of study on the influence of climate and underlying surface changes on the runoff of the Yarlung Zangbo River Basin because of its scarce observation data. Therefore, based on the daily meteorological data and the monthly hydrological data of Nuxia station during 1986—2010, as well as dynamic land use data, this study comprehensively investigated the influence of climate and underlying surface changes on runoff at different period from 1991 to 2010 in the Yarlung Zangbo River basin, with the final goal of clarifying the discharge variation mechanism of the high-altitude watershed by means of the improved distributed hydrological model in association with different simulation strategies. The results suggested that: (1) During 1991—2010, the contribution rate of climate change and underlying surface change to runoff variation varied greatly in different periods, and the contribution rate of climate change to runoff variation was higher than that of underlying surface change, which increased runoff during the period. (2) In spatial perspective, the contribution of climate change to runoff was larger in the upper and middle reaches, but smaller in the northeast of the lower reaches where the underlying surface changes contributed relatively large. (3) Runoff from snow and ice ablations tended to increase with climate warming, their average contribution to the annual total runoff of the basin was in the range of 21.1% to 48.6% approximately, and the average long-term contribution was about 33.6%. The snow-ice melting runoff started to increase from April of a year, reached to the maximum in August of the year, and approached to the end of ablation in October in general. The implementation and findings of this study is not only the need of basic research on hydrology and water resources in the Yarlung Zangbo River basin, but also has important theoretical significance. At the same time, it can also provide scientific theory and decision-making basis for the protection, planning and management of water resources in the basin, which has important practical significance.

Key words: climate change, underlying surface change, runoff, snow-ice runoff, Yarlung Zangbo River basin
