Abstract: Studies on plant regeneration have been one of the problems in the ecological field since 1970's. Lots of studies on factors influencing the regeneration of seed plants have been carried out, and mainly involved 3 stages, i.e., seed production, seed movement(mainly seed dispersal), and seed germination,seedling establishment and sapling maturity. Some detailed theoretical and experimental models were put forward, and promote field researches further. Many qualitative models and quantitative models have been proposed, and there was a tendency of carrying quantitative studies on regeneration of seed plants. The paper reviewed 3 qualitative models, i.e., Chambers et al . model of seed fates,Clark et al .'s models of recruitment limitation and Nathan & Muller Landan's spatio temporal model; and 2 quantitative models, i.e., Vander dispersal model of Purshia tridentata seeds and Bhning et al .'s dispersal model of Commiphora guiliamini seeds, which appeared in recent years.
