Laser induced breakdown spectroscopy （LIBS） is one of the important means to monitor the key parameters of combustion process. A three-dimensional movable experimental measurement platform of LIBS was built, then the spatial structure of propane laminar premixed flame was studied by combining plasma energy and spectroscopy, and the temperature trends and equivalence ratio spatial distributions with different equivalence ratios and heights were obtained. The results showed that the thickness of premixed combustion zone of Bunsen flame increased with the increase of height, and the spectral line intensity of H, N and O was consistent with the change trend of plasma energy, indicating that the particle volume fraction is the main factor affecting plasma energy. Then the spatial distribution of local equivalent ratio was obtained by calibrating the relationship between H656/N746 and equivalence ratio.
