Abstract Shazaoyuan granite masses is a key pre-selection area for high-level radioactive waste disposal in China. Outcrop joints widely distributed in the granite body are the channels for groundwater seepage and nuclide migration. On basis of previous outcrops survey and measurements，taking a single outcrop as an object，the circular window method was used to calculate the average trace length L and the number of unit area of the outcrop；the topological theory was used to calculate the number of connection nodes per unit joint，and the box counting method was used to calculate the fractal dimension D of the outcrop. Secondly，the linear correlation of plane characteristic parameters was analyzed，in which is positively correlated with L and D，and the coefficients are 0.418 and 0.612，while is negatively correlated with L and D，and the coefficients are －0.538 and －0.387. and do not reflect the correlation，and the area density parameter of connected nodes of outcrop joints was proposed. Then，taking outcrops in the area as an object，based on location of outcrops，the Voronoi method was used to divide the rock mass. The regional plane characteristic parameter value = 13.54 m， = 0.095， = 2.93， = 1.19， = 0.25 obtained by the area weighting method. Finally，the regional distribution of parameters is presented by the quartile map，in which the regional distribution of is obvious，showing the characteristics that the southwest region is larger than the Northeast. The regional distribution of parameters ，L and D is similar，showing that the area is small in the middle and alternated around. The rock mass was screened by parameters ， and . The areas with“good”rock mass quality are located in the middle and east of the investigation area.
