The mechanism of addition and hydrogen abstraction reactions between NH2(X^2B1) and C2H4 has been investigated using ab initio calculation at MP2/6- 311G^** level of theory. The transition states of the two reaction paths are obtained and verified by vilbration analysis and IRC calculations. The barriers and classic rate constants of the two reactions from 1500K to 2000K were calculated and compared with experimental data. The results show that addition reaction is dominant reaction channel. The information along the two reaction paths was gained.
