| Abstract: | The features of greening land surrounding 41 overpasses along expressway in Beijing were analyzed based on data from Quick Bird satellite. The results indicated that the similarity between on site survey and satellite identification was 88.3 %, and the accuracy for trees was the highest. The dominant greening lands were mainly woodlands and turfs,and their areas were 868 800 m^2 and 820 700 m^2 respectively,which accounted for 49.97% and 47.20% of total greening land area. The area of shrubland was the smallest（49 100 m^2）. The number of common plant species was 28 belonging to 14 families. |
