There are 33 land- scape plants, including 13 trees and 20 shrubs. There are 26 newly-introduced landscape plants, including 10 trees and 16 shrubs. The main landscape plants in Bayi Town could absorb 245.6 t of CO2 and release 178.66 t of 02 per year, illus- trating significant ecological effect. According to the theory that 25 m2 of lawn or 10 m2 of tree could completely absorb the CO2 breathed out by one person daily, the current green space in Bayi town could satisfy the requirement of 43 400 people. We also found that the maximum amount of retained dust by the garden plants is 12.8 t per year, which is considerable and consistent with the results from other studies.展开更多
