The top and bottom edges of 1 000 impact craters are extracted by manual vectorization in the remote sensing images evenly in this paper. All the parameters, r1, r2 and h, are researched by fractal analysis, statistical analysis and cluster analysis. The results show that: 1) the fractal dimension of the impact craters’ number with r1 and r2 is D1=1.88 and D2=1.51, respectively. They are both larger than the fractal dimension of the impact craters on the earth; 2) there is a good liner correlation between r1 and r2, and the clustering results will be divided into three categories; and 3) the coefficient of determination R2=0.968 is obtained by the liner fit of three parameters r1-r2-h, which shows that there is also a good liner correlation among r1-r2-h.
