The spermatophyte consists of 1 445 species which belong to 678 genus and 153 families in Nanhe Nature Reserve by scientific survey and historical data.Based on the analysis of the floristic elements from the level of genera and family rank,the results showed that the faunal composition is complicated and various in the reserve which have 12 types of family level in Chinese spermatophyte distribution area,and have subtropical and northern flora characteristics.Topical genera account for 34.54%of total 15 types,211 genera,and the total 374 genus of temperate genera represent 61.22%,which reveal the flora is temperate,have subtropical to temperate transition characteristics.There are 26 endemic genus of China indicate the flora is old.
