Abstract: The study aims to fully understand the spatial-temporal pattern of climate change around of Qinghai Lake, furthermore, to reduce the deficiency in understanding the dynamic process of climate change in the area of Qinghai Lake basin and its surrounding areas under the condition of warming in Qinghai-Tibet Plateau. Daily and monthly rainfall data from 1961 to 2013 at five weather stations in the south region of Qinghai Lake were used in this paper, annual and seasonal precipitation data, as well as the precipitation days in different levels were analyzed by linear regression and moving average method. We also tested the mutation of precipitation by Mann-Kendall method. The results showed that the annual rainfall had a weak increasing trend with a growth rate of 4.42 mm per decade in the studied area in 1961-2013, it was mainly contributed by the precipitation trend in summer, spring and autumn. The tendency of precipitation showed a clear increase in spring, summer and winter except autumn, and precipitation increase in summer was more obvious. The most wide rainfall amplitude appeared in summer, and then in autumn, spring and winter as a sequence. The amount and intensity of rainfall tended to increase in the summer half year, with a decrease trend of light rain days and an increase trend of both days and amount of moderate rain. However, in the winter half year, snow days of light snow declined but the intensity increased. Our analysis indicated that among the different levels of precipitation, there was an increased trend of days and amount of moderate rain, while there was a decreased trend of light rain days, amount and intensity. Precipitation mutation test indicated that two mutations occurred in 1976 and 2004 for average annual rainfall, it experienced an obvious change from rainy period into dry period in 1976 with a difference of average annual rainfall of 158.4 mm, in contrast, the precipitation showed a change from dry to rainy after 2004 mutation with a difference of 95.5 mm.
