The Kepler Mission which launched in 2009 March focuses on detecting potentially habitable terrestrial-sized planets. To date the Kepler mission has released more than 4000 planetary candidates. There are plenty of planet pairs trapped near the first order mean motion resonance (MMR). From the statistical results of numerical simulations based on the formation scenario we proposed for the planetary configurations near 3:2 and 2:1 MMRs, we find that the proportions of period ratios close to 1.5 and 2.0 can arrive at 14.5% and 26.0%, respectively. This scenario may explain the formation of Kepler candidates pairs in near 3:2 and 2:1 MMRs.
