In order to reveal the laws of forest vegetation artificial restoration in severe fire area in Daxing’anling Mountain, with the method of deducing time series from spatial series for vegetation succession, we analyzed the succession process of Larix gmelinii forest with artificial restoration in severe fire area in Daxing’anling Mountain. The results showed that, early after the fire, the number of shrubs and herbs species increased fast. As time goes on, the number of shrubs and herbs species started to reduce, and the herbs reduced stronger. As time goes on, the coverage of arbors and shrubs increased, but the herbs showed an opposite trend. We found in species similarity study that it was high to shrubs similarity in different years. And the herbs had a high similarity in the years closer, and a low similarity in the years further. And as time goes on, the similarity became lower. After the severe fire, artificial recovery accelerated the recovery of the forest. The results showed that after 25 years, the artificial restoration of Larix gmelinii forest had the same state with the Larix gmelinii natural forest which was not be burned.
