Taking the flora of Wula Mountain as study object,we analyzed geography distribution,life styles,water ecotypes of seed plants here from taxonomic grade of families,genera and species.The results compared with the flora of Inner Mongolia.The conclusions are as follows:(1)There are 426 species of seed plants in Wula Mountain,which belong to 227 genera and 67 families.Among them there are 3 families,5 genera,7species in Gymnosperm;58 families,187 genera,345 species in Dicotyledon and 6 families,35 genera,74 species in Monocotyledon.(2)Temperate components are dorminant.Herbage is dominant in life style.In water ecotype,the mesophyte is most primary,the xerophile is primary either.That means the water condition is worse and here is semidrought area.Compared with the flora of Lang Mountain,Jiufeng Mountain and Daqing Mountain,the kindred relationship between them were analyzed:the flora of Wula Mountain has near kindred relationship with Daqing Mountain in families and genera,with Jiufeng Mountain in species,but not with the flora of Lang Mountain.
