Abstract：In order to find out variation model of soil seed bank under different vegetation restoration methods in dry-hot valley,soil seed bank of vegetation restoration region in Yuanmou dry-hot valley mountainou was(investigated) by comparative methods,by which soil seed bank's composition and size between different soil management and pasture contrast were compared.The results showed that,density and species richness of soil seed bank in vegetation restoration region is superiority to contrast,density and species richness of soil seed bank of two years is higher than one year in restoration region,difference of soil seed bank density was notability among management measures,there was an absolutely high proportion of herbaceous species in the seed bank and the most frequent seeds were Bothriochloa pertusa(L.) A.Camus and Heteropogon contortus(L.) Beauv.
