UMEZU, Yukio (Midorigaoka Middle School, Ooita) 1978. Mapping of air pollution intensity by epiphytic bryophyte and lichen communities in heavy industry region. Jap.J.Ecol., 28 : 143-154. From the phytosociological table of epiphytic bryophytes and lichens in a climax forest ((Symploco lucidae-Shiietum cuspidatae) it was concluded that Parmelio-Sematophylletum japonici, Heteroscyphetum plani and Isopterygletum pohliaecarpi are the associations found in the natural atmospheric condition and most susceptible to air pollution. Glyphomitrletum humillimi and Haplohymenietum pseudo-tristis are much more tolerant. In the area near the source of pollution thrive Ptycoleus nipponicus-Venturiella sinensis and Pohlia-Scopelophila cataractae-community. Index of air purity was calculated from the coverage of species by means of the method proposed by TUXEN & ELLENBERG (1937) in each community. As the result of it, five zones of pollution intensity were discriminated, and they were illustrated in a map.
