Abstract: Because of special geographical location and genesis, there are unique ecological characteristics and huge scientific value in Wudalianchi. According to the theory and methods in floristic, floristic analysis on spermatophyte genera in wudalianchi was studied. The analysis showed that: (1) The Wudalianchi seed floristic composition is abundant, there are 869 kinds of seed plants belonging to 369 genera and 99 families. The ratio of single-species and few species is very high, reaching 89.16% of total area. (2) The composition of floristic is complex, it contains 14 distribution type and10 variants type. The temperate elements of genera dominate obviously. (3) The origin of the flora is ancient, China unique genera is not obvious.

Key words: Wudalianchi, spermatophyte, genera, floristic analysis
