Abstract:
Comparison of dust-retention capabilities of 11 green plants grew on 7 main roads in Shijiazhuang was made.A correlation formula for the amount of total dust-retention per leaf of green plants corresponds with dust-retention time that was constructed.The factors that dust-retention time，the leaf surface micro morphology，leaf traits，the height between leaves and the ground，and the condition of roads were analyzed，to find out the difference of dust-retention capacities of the green plants.The results showed that Ligustrum vicaryi and Buxus megistophylla had the highest dust-retention capabilities with the record above 4.0 g/m2；Kerria japonica，Malus spectabilis Borkh，Jasminum nudiflorum Lindl and Prunus cerasifera were in the middle，with the record 2.0 g/m2 to 4.0 g/m2；Populus tomentosa, ligustrum lucidum Ait and Syringa oblata var.alba gave a lower result 1.0 g/m2 to 1.5 g/m2；Aesculus chinensis Bunge and Rosa chinensis showed the lowest dust-retention capabilities with the record 0.996 g/m2 and 0.730 g/m2.Two independent samples T-test gave the conclusion that the traffic situation of urban roads and the surrounding environment could significantly influence green plants’dust-retention capabilities.
