Ganzi is situated in the transition zone between the Qinghai-Tibetan Plateau and the Sichuan Basin with a large areas of national nature reserves and marine glaciers. Analyzing the temporal and spatial trends of regional climate change is of special significance for planning tourism development,environmental protection and ecological civilization construction in the region. Based on the temperature and precipitation data from 11 sites in Ganzi during 1961 to 2015,methods of linear regression,anomaly analysis,moving average,Mann-Kendall mutation test,and spline interpolation were applied to analyze spatial and temporal characteristic of temperature and precipitation in Ganzi. The study showed that: Ganzi had a significant upward trend in the annual and seasonal temperatures,with a temperature change rate of 0.242 ℃/10 a for the whole year and 0.176 ℃/10 a、0.211 ℃/10 a、 0.211 ℃/10 a、0.368 ℃/10 a for the spring,summer,autumn and winter temperatures respectively. The increase in winter temperature contributed most to the increase in annual average temperature. Spatial distribution of annual and seasonal temperature variation varied greatly in the area. With the increase of altitude,the rate of warming increased. Although the precipitation in Ganzi Prefecture was generally increasing,the trend was not significant. The annual precipitation increased at a rate of 11.22 mm/10 a,and the seasonal precipitation increased at a rate of 5.23 mm/10 a,4.15 mm/10 a,1.68 mm/10 a,and 0.22 mm/10 a respectively. The increase of precipitation in spring and summer contributed the most to annual precipitation. Annual precipitation tended to decrease from east to west in space,and precipitation may even decrease in the southwestern margin. In general,there is a warming and wetting trend of the climate in Ganzi,and this trend is more pronounced in high altitude areas.
