摘要
By using quadrat sampling method, the community structure and diversity of ground cover plants in the flight area in Tianjin Binhai International Airport were investigated from spring to autumn in 2015. The results showed that 58 plant species were recorded at the airport, belonging to 18 families and 48 genera. Dominant plant species showed seasonal characteristics. Specifically, lxeri chinensis （ Thunb. ） Nakai and Lagopsis supina （ Steph. ） Ik. -Gal. ex Knorr. were the dominant species in spring; Lagopsis supina, Cirsium setosum （Willd.） MB, Plantago asiatica L. , Cynanchum chinense R. Br. and Humulus scandens （I_our.） Merr. were the dominant species in summer; Chloris virgata Sw. and Eleusine indica （L.） Gaertn. were the dominant species in autumn. Quantitative characteris- tics of the dominant species, including the density, frequency, coverage and height, varied in different seasons. In different seasons, changes in the diversity of plant communities in three sampling points were analyzed. The results indicated that plant communities in summer exhibited the highest diversity and the most uni- form distribution. This study provided a theoretical basis for avoidance of bird strike in Tianjin Binhai International Airport.
