摘      要：The paper studied the air purification function of urban forest trees in Guangzhou City in absorbing C、P、K、 SO2、Pb、Cd , etc. The results indicated that: The highest reserve of organic C reaches 184 t/hm2 in the soil of studied urban forest, and the lowest is 24.6t/hm2; The highest TN reserve is 16.7t/hm2, and the lowest is 2.0t/hm2; The highest reserves of Pb, Cd are 837.4kg/hm2, 3.9kg/hm2 and the lowest are 577kg/hm2、 1.2kg/hm2 in the greenbelt ecosystem. The accumulative quantity of SO2 in tree leaves is highest in Ficus altissima, and lowest in sea mango; The maximum quantity of Pb fixed by Ficus concinna is 22.6g/ hm2, and the maximum quantity of Cd fixed by Eucalyptus urophylla and Michelia alba is 0.15 g/ hm2.
