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.展开更多

Sludge compost,waste crumb rubber and fly ash were added in soil at the Tianjin Binhai International Airport. By sampling method,insect community and diversity were surveyed in Tianjin Binhai International Airport. The results showed that a total of 1 288 insects were collected,belonging to 8 orders,17 families and 21 species,with Orthoptera,Coleoptera and Diptera as the dominant groups. The species and individual numbers of insects showed the same trend with the order of sludge control fly ash crumb rubber. Compared with the control area,the individual number and species of insects in the crumb rubber area decreased by 41. 3% and 38. 9%,respectively. Moreover,the species richness and diversity of insects in the crumb rubber area were the lowest,1. 39 and 0. 46 lower than that of the control area,respectively,indicating that crumb rubber can effectively reduce the number and the diversity of insects at the airport.展开更多
