By collecting and analyzing the data from the 71 meteorological observation stations in Fujian Province, the mean annual air temperatures during 1961-1990 were put into order and built into an air temperature database. Based on Digital Line Graphic (in the manner of contour and by the scale of 1:100,000) and supported by ArcGIS, the 100 m * 100 m Digital Elevation Model (DEM) of Fujian Province was created, further to that, a macroscopic geographical factor database was set up including the information of longitude, latitude and elevation. The main result of the paper is that a mixed interpolation model with the integration of the Trend Surface Analysis and Universal Kriging Spatial Interpolation Method was applied, offering a useful approach to effectively imitate the natural spatial distribution of the mean annual air temperature in the study area. The approach would be of important significance to the formation and application of Fujian air temperature resource thematic map and to offer a new thought and methodology for similar research home and abroad.
