Abstract By using the first, second and third electronic burst and transcient source experiment catalogs, a joint analysis of spatial and temporal distributions and hardness ratios of gamma-ray bursts is performed. Turning point features at C_max/C_min ~ 6 are found. This probably indicates the existence of two components of burster population which have distinct spatial distributions.
