Abstract:
ObjectiveTo investigate the distribution of allergenic pollen plants in the central urban areas of Guangzhou， and to provide scientific basis for the prevention and treatment of seasonal allergic rhinitis （hay fever） and reasonable urban greening construction. MethodsThe "Xingse APP" was used to identify the plants in 13 survey sites in the central urban areas of Guangzhou， and the plants that could produce allergenic pollen in the survey areas were screened out. ResultsA total of 102 families， 265 genera， 311 species of plants were found； 38 genera of plants， among which 20 （52.6%） were native to Guangzhou and 18 （47.4%） were not native to Guangzhou， can produce allergenic pollen. The non-native allergenic pollen plant species accounted for nearly half of the total number of sensitized pollen plant species in Guangzhou urban areas， and the distribution density of non-native allergenic pollen plants in each genus was higher than that of native allergenic pollen plants. Poaceae was the most widely distributed， with a discovery rate of 100%. The most abundant sensitive pollen plants were 6 species （15.8%） belonging to Poaceae， which were Cynodon， Echinochloa， Setaria， Pennisetum， Phragmites and Digitaria. Mangifera and Bauhinia were found in 11 sites， and the discovery rate was 84.6%. ConclusionsUnreasonable urban greening has occurred in downtown Guangzhou， and many allergenic pollen plants have been planted. Thirty-eight genera （14.3%） of plants belong to plants that can produce allergic pollen， of which native （52.6%） and non-local （47.4%） allergenic pollen plants account for nearly half. Increasing the types and quantities of gas-sensitized pollen from the source may lead to an increase in the risk of hay fever. When planning urban greening， the cultivation of allergic pollen plants should be reduced.
