| Abstract: | Its various physical environments are made about the seed plants with complex floristic elements around Lian Yuangang Bai Tabu Airport.The observing results show that there are 261species of seed plants,belonging to 190 genera and 73families in Lian Yuangang Bai Tabu Airport.Among them,there are about 4 families,5 genera and 6 speices in Gymnospermeae;56 families,154 genera and 216 speices in Dicotyledoneae;13 familes,31 genera and 39 species in Monocotyledoneae.The families of seed plants are classified into 8 areal types and 4 subtypes,the cosmopolitan,pantropic and North temp areal types were the most abundant types.The 261 genera distributed in Lian Yuangang Bai Tapu Airport can be divided into 14 areal types and 9 subtypes covering 46% of the genera in temp area types.In the distribution of species,there are 71% in the cosmopolitan,13% in the pantropic and temp areas and only 1.2% in Trop.Asia Trop.Amer.disjuncted and Old World Tropics. |
