A basic ingredient analysis of flora and geographic elements of plant genera and families in Daqi Mountain Nature Reserve was conducted through the field survey and specimen collection, based on the system investigation of plant flora, and an R/T ratio comparison between the flora in Daqi Mountain and adjacent mountain floras was made. Plant taxonomy identification indicates that spermatophytes in the nature reserve comprises 1035 species of 534 genera, falling in 140families, of which 10 gymnosperm species of 8 genera fall in 5 families, while 1025 angiosperm species of 526 genera in 135 families. The analysis of flora demonstrates that the region harbors 15 flora distribution types, with high complexity, paleo-flora origin, distinct trait of temperate zone, abundant ingredient of tropical zone, and close connection with the flora of East China.
