Based the time and space resolved spectroscopy and the measurements of intensity of resonant double lines 396.15 nm and 394.40 nm from laser induced plasma, the time and space evolution characteristics of resonance double lines of aluminium in a plasma were obtained and mechanism was discussed. Air was used as surrounding atmospheres. The pressure was set up to 101 kPa.
