This paper analyses the area accuracy loss of all types of land use at different elevation levels in different spatial scales. With landscape pattern indices, it discusses the scale effect of data conversion under the influence of the elevation. The result shows that there are scale dependences between land use types and elevations. To a certain extent, the landscape indices calculated from the original vector data can indicate the change of the laws and the causes of the accuracy loss.
