%X Impact craters are the main geomorphological type on lunar surface.They can provide a large amount of information,including the age of geological unit,the history and evolution of the moon impact.Due to the fact that the current automatic recognition methods for impact craters have deviations of extraction range and locations,simultaneously they can not extract the information of the buttom,thus the whole characters of the impact craters can not be researched deeply.The top and buttom edges of 1000 impact craters have been extracted by manual vectorization in the remote sensing images evenly in this study.The equivalent radius of the top and buttom edges,that is r1(top) and r2(buttom),are computed by the area of the range of the crater's lip and buttom.And h,the height(depth) of the impact craters,are derived from the digital elevation model of the whole moon.Then 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,indicating that the extraneous interference which decides the complexity of the impact craters on the moon surface is lower than that on the earth's,and the complexity of the top is higher than that of the buttom at the same time.(2) There is a good liner correlation between r1 and r2,and the clustering results will be divided into three categories,with the coefficients of determination being R12=0.685,R22=0.886,and R32=0.974,respectively.(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,and the formation of the lunar impact craters is found in the same dynamic environment,the same as the environment after the formation.
