Abstract:: Based on field investigation and statistical data,the paper reported 454 species of seed plant which belong to 71 families,240 genera in Liangshui nature reserve area.There were 1 family,3 genera,9 species of gymnosperas and 70 families,237 genera,445 species of angiosperm.According to the family distribution types,6 distribution types were divided.There were cosmopolitan type 34 families,175 genera and 328 species,tropical type including 16 families, 20 genera and 30 species，and temperate type including 21 families,45 genera and 96 species.According to the genera distribution types,10 distribution types were divided.The temperate elements held absolute predominance with 174 genera of temperate elements accounting for 72.50% of the tatal genus,and also were the main geographical elements of seed plant plora in Liangshui nature reserve area.
