As for the 1km-resolution spatial interpolation of temperature in the area with complex topography,two methods for the interpolation of temperature are presented by the author based on Gaussian weighted method,each of which is appended with a topographic-factor and an error-modifying scheme correspondingly.The method,which can make the resultant temperature distribution match with the topography in the area better was selected.Using this method,and in the area including the mid-upper reaches of the Yangtze River in 2001,the daily temperature's mean absolute error(MAE) of the obtained 1km-resolution graphs of temperature distribution is improved by about 1.2℃ and reduced to 0.43℃ for the mean temperature,and it's root mean squared interpolation error(RMSIE) is improved by about 1.5℃,and reduced to 0.56℃.Apart from above,the daily mean temperature's mean absolute errors of the obtained 1km-resolution graphs of temperature distribution are within 0.77℃through the year.
