%X Variation tendency of rivers runoff, drainage area precipitation and temperature of principle rivers in Qinghai have been analyzed by using nearly 38 years data. Dry climate impact on Qinghai surface water resource was mainly discussed. The results show that inland rivers are mainly supplied by mountains snowmelt and precipitation, and outflow rivers are mainly supplied by precipitation. Qinghai surface water resource is tending to decrease and the tendency is more obvious after 1990s. Temperature and precipitation are primary factors to affect Qinghai surface water resource. Temperature rise aggravated evaporation and drought, reduced surface runoff. Precipitation decrease after 1990s, especially during flood areas, reduced surface runoff directly.
