This paper discusses particularly the method and process of pixelizing the statistical population data. Firstly, the regionalization of spatial population distribution is finished. Secondly, the models of spatial population distribution based on the data of land use and land cover deriving from Landsat TM is established to calculate the population coefficient dwelling on different types of land use. Thirdly, the 1-km gridded population data supported by GIS is calculated. Then the results were modified according to DEM and inhabitant place map. Of course the sub-area data sampling randomly from the first class regions tests the precision of the results.

Key words: population; data; pixelizing
