The invention discloses a natural gas hydrate containing soil sample preparation equipment and a sampling method thereof. The natural gas hydrate containing soil sample preparation equipment comprisesa soil-powder mixture, a reaction kettle, a refrigerating room, a hydraulic pump, a buffering container, a cylinder, a piston, a piston rod, a vacuum pump, a gas bottle, a coil, a cold bath, a flange, a pressure-reducing valve, a spherical valve, a first stop valve, a second stop valve, a third stop valve, a fourth stop valve, a fifth stop valve, a T joint and a four-way joint. According to the program of performing press molding firstly and then generating a hydrate through a reaction by adopting an ice seed method, mixing, reaction, press molding and storage are integrated, so that the problem of difficulty in charging gas is solved, and low-temperature operation is avoided. The whole sample preparation process is carried out under a temperature and pressure controllable environment inorder to lower the unfavor
