This paper studies settles systematically the physical process of the laser indirect-driven ignition target implosion. The theoretical methods and one-dimensional hydro-dynamics simulations are used to give key scaling laws in capsule implosion. Based on these scaling laws, the volcanic islands of capsule mass-radius parameter space are obtained under the given conditions of hohlraum radiation temperature, in-flight adiabat, shaping velocity and ablator material. The variations in performance parameters with radiation temperature, in-flight adiabat, etc. are investigated. When the hohlraum radiation temperature increaseds, the stability of the capsule implosion will be better. And the capsule radius needs to be decreased under the condition that the mass is constant. When the in-flight adiabat increases, the energy gain decreases slightly and the stability becomes better. However the reduction in the one-dimensional ignition threshold factor results in a narrowing of the area of the volcanic island. When the shaping speed increases, the area of the volcanic island becomes slightly larger, and the stability change is not significant. The capsule radius needs to be increased under the condition that the capsule mass is constant, which causes larger aspect ratio. When the shell ablator material is changed to improve the mass ablation rate and the ablation pressure, the energy gain is larger and the stability is better. The capsule radius needs to be decreased under the condition that the capsule mass is constant.
