In this paper,the fractal theory,multivariate regression analysis and grey relational analysis are applied to analyzing the spatial fractal character and its scale character of land use as a case study of Cixi City and Guizhou Province with scale of 1:100 000 and 1:1 000 000 respectively. The perimeter-area relationships of patches of different land types of Cixi City and Guizhou Province under different scales are established;the fractal dimensions of spatial structure of different scale regions of China are calculated.The fractal characters of land use structure in Cixi City and Guizhou Province are analysed,the relationships between fractal dimension of land spatial structure and patch number,average patch area and average patch shape index are established by multivariate regression analysis.It is indicated that patch number,average patch area and average patch shape index mainly influence the fractal dimension of spatial structure of land use,and the spatial fractal character of land use exists over scale.Based on the grey relational analysis,it is further found that patch number is the most important factor that influences the land fractal structure of Guizhou Province,and average patch shape index for Cixi City.Although the land spatial fractal structures of Cixi City and Guizhou Province are mainly influenced by the geometric characteristic of spatial pattern of land use.
