An important theme of this paper is to search for more genelalities of diversity and distribution pattern on the trampled plant communities in Daegu area. A total of 50 phytosociological releves were analyzed by the Zurich-Montpellier School's method and generalized habitat characteristics by using Euclidean coefficient and PCoA (Principal Coordinates Analysis). Five plant communities were classified and matched into largely two physiognomic types: grass-types such as Eragrostis ferruginea community, Eleusine indica community, Setaria viridis community, Digitaria ciliaris community, and forb-type of Plantage asiatica community only. These plant communities correspond to quite distinctive four habitat types, with both soil stability and moisture in microhabitat conditions: stable-moderate, unstable-moderate, stable-dry, and unstable-dry. Top-ten species showing the highest relative net contribution degree(r-NCD) were Digitaria ciliaris, Eleusine indica, Eragrostis ferruginea, Plantago asiatica, Echinochloa crus-galli, Trifolium repens, Polygonum aviculare, Setaria viridis, Setaria glauca and Artemisia princeps. The front three species showing more than 50% in percent r-NCD possess florescence after monsoon season. It is critically pointed out that the regional ecological differentiations i.e. the Daegu bioclimatic division, the $C_4$-plant dominant season(post-monsoon) of Korean peninsula, and species composition different from Japan's Plantaginetalia asiaticae, are the basis for deriving characteristics of the roadbed trampled plant communities of Daegu.
