A statistical analysis of short-period comet complex (N = 250 objects, period P < 200 years) is carried out. Orbits distributions according to the major semiaxis value, eccentricity, perihelion and aphelion distances, heliocentric nodes distance, perihelion argument, inclination, mean motion n are given. A classification of comets according to mean motion n values is suggested. It is shown that Jupiter-family (N = 136 comets) is localized by depression with n = 598.2"(commensurability with Jupiter is 1/2) and n = 358.9" (commensurability with Jupiter is 5/6). Average statistical characteristics of the cometary orbits with n < 120.5" (commensurability with Saturn is 1/1) are close to the corresponding parameters of near-parabolic comets (P > 200 years).
