According to the temperature and precipitation data in 1961-2012 from 15 meteorological stations in Shanxi-Shaanxi gorge,we applied the trend analysis,Mann-kendall mutation test,and Z index methods to analyze the climatic change and drought-flood disasters in recent 52a. The results show: (1) in recent 52a, Shanxi-Shaanxi gorge had experienced an apparent trend to climate warming and drying,and the mean annual temperatures were also witnessed a fluctuated upward trend with growth rate of 0. 278℃ /10a. Spatial differences were significant in the field of temperature. (2) Precipitation was witnessed a fluctuated decreasing trend with the rate of 12. 54mm/10a. Besides,it had also appeared roughly zonal disciplinarian in precipitation spatial distribution. (3) After the temperature mutation,the scale of flood disaster decreased,while the scale of " normal" year and drought disaster increased at the same time.
