Abstract: In order to study the spatial and temporal distribution of precipitation characteristics of Shaanxi fruit district, the temporal and spatial distribution characteristics of precipitation in nearly 50 years of Shaanxi fruit district was analyzed by using EOF (empirical orthogonal function) distribution and trend method, based on precipitation data of nearly 50 years from 1961 to 2010 at 29 weather stations in Shaanxi fruit district. The results showed that: the precipitation of Shaanxi fruit district presented a fluctuation decreasing trend, and the climate tendency rate was -18.5 mm/10 a; the space field was divided into the overall consistency and the south-north inverting type, and the generally consistent type was the main form of it. The space-time coefficient fluctuates strongly, which indicated that the precipitation of Shaanxi fruit district showed a large interannual concussion.
