By means of using the spectrum tomography combining with the principle of numerical calculation,reconstruction of plasma flow temperature,density,pressure and velocity fields were proposed. Intensity of spectrum line was collected by CCD scanning system of fiber probe. Then,according to relative intensity method,the temperature field was obtained. Using plasma flow physical equations,other parameter fields were gotten. The spatial distribution characteristics of plasma flow temperature,density,pressure velocity field and intrinsic relation of them were completely analyzed.
