A panel count method and a phospholipid fatty acid analysis technique were used to investigate the responses of Di-(2-Ethylhexyl) Phthalate (DEHP) pollutants to the phyllosphere microbial communities of Chinese Cabbage. The results of plate count analysis showed that the number of culturable microorganisms could be lower than that of water spray after treated with a certain amount of DEHP pollutant. The results of phospholipid fatty acid analysis showed that DEHP pollution treatment had certain effects on the biomass and community structure of leaf microorganisms in leaves of Chinese Cabbage. After spraying 1d, the biomass of the total leaf microorganisms, fungi and bacteria in the leaves of vegetables decreased, which was significantly different from that in the control and the blank groups. There was little change in the ratio of the characteristic phospholipid fatty acids between gram positive bacteria and gram negative bacteria.
