We study a classical 1-dimenslonal kicked billiard model and investigate its transport behavior. The roles played by the two system parameters a and K, goveing the direction and strength of the kick, respectively, are found to be quite crucial. For the perturbations which are not strong, i.e. K＜1, we find that as the phase parameter α changes within its range of interest from -π/2 to π/2, the phase space is in tu characterized by the structure of a prevalently connected stochastic web (-π/2 ≤α＜0), local stochastic webs surrounded by a stochastic sea(0＜α＜α/2 ) and the global stochastic sea (α＝π/2). Extensive numerical investigations also indicate that the systems transport behavior in the irregular regions of the phase space for K＜1 has a dependence on the system parameters and the transport coetticient D can be expressed as D≈D0(α)Kf(α).For strong kicks, i.e. K >1, the phase space is occupied by the stochastic sea, and the transport behavior of the system seems to be similar to that of the kicked rotor and independent of α.
